The specs every platform actually requires, and why one master file covers them all
Your wine could be extraordinary. But if the product image is the wrong size, wrong format, or wrong background color, the listing gets suppressed, the thumbnail looks cropped, and the sale never happens.
Every ecommerce platform, marketplace, and retailer portal has its own image requirements. Pixel dimensions, file formats, background colors, product fill ratios. Get any of them wrong and your listing either looks amateur or disappears entirely.
The short answer: produce one master file per SKU, a high-resolution PNG on a transparent background at 2,000 pixels or more on the longest side. Every spec below is an export from that file, not a new shoot.
Most image size guides copy their numbers from other image size guides. This one checks each figure against the channel's own documentation and labels it:
A beautifully shot bottle means nothing if the file is 400 pixels wide on a platform that requires 1,000 minimum.
Walmart will unpublish your item. Amazon can suppress your listing. Instacart will show a placeholder instead of your label. Your DTC site will stretch a low-resolution file until the label text blurs into noise.
The visual quality of your product imagery is only half the equation. The other half is technical compliance: the right dimensions, the right format, the right background, delivered in a file that every platform can actually use.
Most beverage brands learn this the hard way. A new retail partner requests images for their portal. The images exist, but they are the wrong aspect ratio, or shot on a gray background when the spec calls for pure white. Now the team scrambles to reshoot or reformat, and the listing launch slips by a week.

Before the platform-specific breakdown, here is what the vast majority of ecommerce channels share in common.
At least 1,000 x 1,000 pixels. This is the zoom threshold on Amazon and Instacart and a practical floor everywhere else. Below it, shoppers cannot zoom in on label details, and your listing looks less trustworthy next to competitors who meet the standard.
Square aspect ratio (1:1). The most universally accepted format. A square image fits cleanly into grid layouts on marketplaces, search results, and category pages. When in doubt, produce square. The exceptions: Uber Eats wants wider-than-tall images, and Commerce7 and LCBO are happy with tall bottle crops.
White or transparent background. Pure white (RGB 255, 255, 255) is the standard for marketplace main images. Kroger and LCBO also accept transparent. This is where a lot of existing wine photography fails: that tastefully moody cellar shot will not pass Amazon's or Walmart's check.
Product fills about 85% of the frame. Instacart specifies it, and it is the widely reported Amazon standard. The bottle should dominate the image, not float in a sea of whitespace. Tight but not cropped. Label readable. Closure visible.
JPEG or PNG. JPEG for white-background hero shots (smaller file size, faster loading). PNG when you need transparency or the crispest possible label detail. Every channel with a published spec accepts both.
sRGB color space. Not Adobe RGB, not CMYK. Web browsers and ecommerce platforms display sRGB. Export in any other color space and your label colors will shift.

Amazon checks every main image automatically, and the check is strict.
Amazon's check reads pixel values, not overall impression. A light gray studio sweep that looks white to the eye can still fail.
Secondary images allow more creative freedom: lifestyle shots, label close-ups, back labels, and group shots. But the main image must be clinical.
At least 500 pixels on the longest side, and 1,000 or more to turn on zoom. The main image must sit on a pure white background with no text or logos. We recommend exporting at 2,000 x 2,000 px.

Walmart publishes the highest recommended size of any marketplace in this guide, and it enforces the floor automatically.
Below 500 x 500 px, Walmart unpublishes the item automatically.
Walmart recommends 2,200 x 2,200 px, needs 1,500 x 1,500 px for zoom, and unpublishes items below 500 x 500 px. The main image must be on pure white.

Instacart's requirements mirror the grocery and CPG standards it inherited.
A non-compliant image is not displayed. Your product stays listed, but shoppers see a placeholder or another source's image instead of your label.
For wine brands entering grocery retail or on-demand delivery, a compliant front image is the difference between a listing that sells and one that looks abandoned.
A square image at 1,000 x 1,000 px (600 x 600 minimum, 4,000 x 4,000 maximum), PNG or JPG under 3 MB, on a pure white background with the product filling 85% of the frame. Only the front image is required.

Uber bought Drizly in 2021 and closed the Drizly app in 2024. Alcohol delivery now runs through Uber Eats, under its catalog photo guidelines.
Non-compliant photos are rejected at upload.
Note the aspect ratio: unlike nearly every other channel on this list, Uber Eats item photos are wider than they are tall. A square or tall bottle shot needs to be placed on a wider canvas before upload.
Item photos should use a 5:4 to 6:4 aspect ratio, between 550 x 440 and 10,000 x 10,000 pixels, in JPG, PNG, or GIF format under 10 MB. One product per image, centered, with no text overlays.
Not published. Vivino's public content guidelines cover photo authenticity, not size or format.
Vivino matches wines by label recognition, which means image quality directly affects how well your product is identified and shown to shoppers. A poor image is not blocked. It is just harder to find.
A blurry photo or an angled shot makes it harder for Vivino's scanner to match your product. Your image is quite literally how your wine gets found.
Vivino does not publish a size. A sharp, front-facing bottle shot with the whole label visible matches most reliably; we recommend 1,200 px or higher.
Retail partners are where the front image most often decides whether the product gets into the catalog at all.

Total Wine states that product images are required to sell a product online, and that images not meeting its guidelines "will not be available for sale on the site or in the app." That is the firmest enforcement language of any channel in this guide.

LCBO has the largest pixel requirement in this guide, and the most specific rules about how the shot should look.
At least 4,400 pixels tall at 300 DPI, as TIF, JPG, or PNG between 1 and 10 MB, on white or transparent. A standard 2,000 px master is too small for LCBO; export from a larger source, such as a Studio Super HD file at 6,000 px.
Not published. Wine.com's vendor requirements live in a gated supplier extranet, and no public size, format, or view requirement exists.
You will often read that Wine.com asks for front, back, and group views. We could not trace that to any Wine.com document. If you sell through Wine.com, ask your vendor contact for the current guide.
Secondary only. Target Plus is invite-only, and its content requirements sit inside the partner portal.
The figures that circulate (1,200 to 2,400 px square, JPG, RGB, white background, three or more images) come from onboarding agencies and integration partners, not from Target. Use them as a starting point and confirm against the portal once you are onboarded.
On your own store, nothing checks your images at upload. No validator, no rejection. A poor image goes live and quietly sells less.
Official. Source: Commerce7 documentation, optimal image size.
Commerce7 is the DTC platform of record for a large share of wineries, and it absorbed WineDirect's ecommerce business after acquiring its SaaS division in January 2025. Its image guidance is flexible, which puts the consistency burden on you.
Commerce7 is one of the few platforms that accepts tall, non-square bottle shots natively. Upload the highest resolution you have and let the platform generate the display sizes.
Commerce7 recommends 2,048 pixels on the longest side, and the image does not need to be square. A tall bottle shot works as-is, and Commerce7 automatically generates seven display sizes from your upload.
The built-in bottle shot option. Outshinery Lite has a native app in the Commerce7 app store, the only bottle shot generator with one. From any Product Details page, choose Actions, then Bottle Shot via Outshinery Lite: upload your label and a photorealistic 1,440 x 2,160 px PNG on a transparent background arrives by email within about an hour.
WineDirect's classic platform shuts down on December 31, 2026, and remaining stores are migrating to Commerce7. WineDirect's documented default image size was 250 x 450 px, a fraction of Commerce7's recommendation, so carried-over images will look soft on the new store.
Commerce7 handles the data migration, but a platform move is the natural moment to audit your image library instead of carrying an inconsistent one into a new store. If your products live as high-resolution masters on transparent backgrounds, the new catalog looks consistent on day one. If they are a patchwork from years of one-off shoots, fix the library before the move, not after.

Your own DTC site gives you the most control, and the most room for error. No automated validator will reject your upload. But your customer's eye will.
The critical discipline on DTC is consistency. Every product in your catalog should use the same angle, the same lighting, the same background treatment, the same framing.
When one Chardonnay was shot on a white sweep and the next was photographed on a kitchen counter, your product grid looks disjointed. Shoppers notice, even if they cannot articulate why.

Google is not a store, but its Merchant Center feed decides whether your products show in Google Shopping results and free listings. For more on feeds, see Make your bottle images Google-ready.
Google has been flagging undersized images in Merchant Center since April 14, 2026, and enforcement starts January 31, 2027. Google says it will automatically enlarge some smaller images to prevent disapproval, but the reliable fix is submitting a larger file.
If your store feeds Google small thumbnails, fix it before the deadline.
No. Not one channel with a public spec requires a back-label or side-panel image before a product can go live.
Extra angles still help. Kroger and Instacart both encourage them, and Walmart links more images to better ranking. They help a listing sell. They do not decide whether it goes live.
The open question is Total Wine & More, which blocks online sale for non-compliant images but does not publish what compliant means.
Marketplace main images leave no room for creativity. Everything else does.
Amazon's secondary image slots, your DTC hero sections, email headers, and social posts all accept colored or styled backgrounds. That is where a brand color behind the bottle earns attention that pure white never will.
Two rules keep it from going wrong. First, the channel decides: colored backgrounds belong where no validator is checking for pure white. Second, consistency beats novelty: pick one background treatment per context and apply it to every SKU. A mixed grid is one of the most common product image mistakes on ecommerce sites.
This is also the strongest argument for the transparent master file. Start from a transparent PNG and any background, pure white for Amazon, a brand color for your homepage, a styled scene for social, is one export away. No reshoot.
JPEG remains the standard for marketplace hero shots on white backgrounds. Smaller file sizes mean faster page loads, and every major platform accepts it.
PNG is the better choice when you need transparency (for compositing onto different backgrounds) or when label detail, fine text, and sharp edges matter. PNG files are larger, but the quality difference on a detailed wine label is visible.
WebP is the standard for web performance. It delivers smaller file sizes than JPEG at comparable quality, and Shopify serves it automatically. But most marketplace and retailer portals in this guide do not list WebP as an upload format. Produce your master files in PNG, and let your website platform handle WebP conversion.
AVIF is the newer web format. It usually compresses smaller than WebP at the same visual quality, and every current major browser supports it. Webflow, which runs this site, serves AVIF automatically. But none of the channels in this guide list AVIF as an upload format, Google Merchant Center included. Treat it the same way as WebP: a delivery format your website generates, never a file you upload to a marketplace or keep as a master.
The practical answer: produce your master product images as high-resolution PNGs with transparent backgrounds. From that single file, you can generate JPEGs on white for Amazon and Walmart, PNGs for your DTC site, and let your CMS convert to WebP or AVIF for performance. One master, every format covered. For the fundamentals behind these choices, see our guide to image formats and resolution.
If your product images were produced at high resolution with a clean, transparent background, you already have what you need for almost every platform on this list. Resize, flatten to white background, export as JPEG. Done. The two exceptions are LCBO, which needs a larger source file, and Corksy, which needs a smaller export.
If your images were shot at 1,200 pixels on a gray background with a slight shadow, you have a problem that multiplies across every channel. Too small for Walmart zoom. Wrong background for Instacart and Amazon. Inconsistent with whatever you already have on your DTC site.
This is the real cost of "good enough" product photography. It is not that any single image looks bad. It is that the image cannot travel. It works on one platform and fails on three others.


Outshinery delivers high-resolution renders on transparent backgrounds that export to the marketplaces, delivery apps, and DTC stores in this guide. Whether you work with Studio for complex packaging and custom scenes, or use Lite for fast, self-serve wine bottle shots, the technical specs are handled from the start, without a photoshoot. For LCBO and other large-format needs, Studio's Super HD option delivers 6,000 px files, well above LCBO's 4,400 px minimum. No reshooting. No scrambling when a new retail partner requests images in a format you do not have.
Some channels keep their image requirements behind supplier logins. Rather than guess, here is what remains unconfirmed as of September 2026:
If you have access to one of these portals and are willing to share the current requirements, we will add them.
Produce one master file per SKU at 2,000 pixels or more on the longest side, as a PNG on a transparent background. That file exports cleanly to Amazon, Instacart, Kroger, Commerce7, and Shopify. Walmart recommends 2,200 x 2,200 px, and LCBO needs 4,400 px tall, so keep the original at the highest resolution you have.
Marketplace main images do. Amazon, Walmart, and Instacart require pure white (RGB 255, 255, 255), and Walmart states that off-white and light gray do not qualify. Kroger and LCBO accept transparent. Secondary images, DTC hero sections, email, and social all accept colored or styled backgrounds.
No channel with a public spec requires one. Instacart, Amazon, and Walmart treat back labels as optional extra images, Kroger requests them without requiring them, and LCBO asks for a single front shot.
Keep the master as a transparent PNG, export JPEGs on white for marketplaces, and let your website convert to WebP or AVIF for performance. Most marketplace and retailer portals do not list WebP as an upload format, and none in this guide list AVIF, so neither should be your master format.
sRGB, not Adobe RGB or CMYK. Web browsers and ecommerce platforms display sRGB, so exporting in any other color space shifts your label colors on screen.
About 85 percent on marketplace listings. Instacart specifies it, and it is the widely reported Amazon standard. Google recommends 75 to 90 percent. Keep the label readable and the closure visible, tight but not cropped.
It depends on the channel. Walmart unpublishes items below 500 x 500 px. Amazon can suppress the listing. Instacart hides the image but keeps the product. Kroger will not accept a new item without a front image. Total Wine will not sell the product online. Your own store accepts almost anything.
Verify every product image against these specs before uploading to any channel:
If any product in your library fails one of these checks, that listing is underperforming. Not because the wine is wrong. Because the file is.
