Product Photo Studio

Product Photo Studio: White Background, Square Canvas and Marketplace Compliance Check

Product Studio turns a raw product photo into a marketplace-ready image in your browser: automatic background removal, a pure-white (or custom-colour, or transparent) square canvas at the exact pixels Amazon, eBay, Etsy, Shopify and Instagram expect, an optional soft drop shadow, and batch processing with a ZIP download. Every step runs locally on your device - the photo is read into a canvas, the cutout mask is computed on-device, and the result is generated without uploading a single byte to a server.

The 2026 upgrade adds a built-in main-image compliance check. After processing, pick Amazon, eBay, Etsy or Shopee from the dropdown and the tool measures the output canvas for you: aspect ratio, longest edge, white background (eight-point corner and edge sample), and product fill (from the cutout mask). It returns a pass/fail list per image, so you can re-process with a higher coverage slider before you upload. The rule library is a static JSON file shipped with the site; thresholds are re-checked against each platform's public seller guidance.

• Built-in main-image compliance check for Amazon, eBay, Etsy and Shopee
• Touch-up modal: paint to erase leftover background or restore removed product

How to use

1. Drag one or more product photos onto the drop zone, or click to choose files.
2. Pick the marketplace preset (Amazon, eBay, Etsy, Shopify, Instagram) and a background.
3. Adjust the product-in-frame coverage and decide whether you want a soft shadow.
4. Press Process all photos. After processing, run the compliance check for your target marketplace.
5. Download individual images, or press Download all as ZIP for the whole batch.

What the main-image compliance check actually measures

After the batch finishes, the checklist reports four measurements per image for the platform you selected. The first is aspect ratio: square platforms (Amazon, Shopee) require width and height within a 1% tolerance; eBay also accepts 16:9. The second is longest edge: it must meet the platform minimum (Amazon 1000, eBay 500, Etsy 635, Shopee 500) and you get a warning if you are below the recommended zoom threshold.

The third measurement is the background. The tool samples eight points - the four corners and the four edge midpoints - and counts how many are within tolerance of white. Amazon uses a tight tolerance of 2 (RGB 255,255,255); eBay, Etsy and Shopee use a relaxed tolerance of 25 and require at least six of eight points near white. The fourth measurement is product fill: it uses the on-device cutout mask, counts pixels with alpha above 128, divides by total pixels, and compares to the platform minimum (Amazon 85%, eBay 70%, Etsy 65%, Shopee 60%) and to Shopee's upper bound of 90%.

• Ratio: square platforms pass only on width and height within 1%.
• Longest edge: compared to platform minimum, with a zoom-threshold warning.
• White background: 8-point sample (four corners + four edge midpoints).
• Product fill: cutout-mask pixel ratio vs platform minimum (and Shopee 90% max).
• Watermark, text and border detection is a visual reminder, not a hard fail.

When to turn the soft shadow on or off

The soft drop shadow adds a faint, blurred shadow under the product so it sits on the white canvas rather than floating. It looks good on your own store, on social media, and on marketplaces that do not enforce a pure-white rule. But for a strict Amazon main image, leave the shadow off: Amazon's rule is pure white RGB(255,255,255) with tolerance 2, and a visible shadow along the bottom edge is the kind of thing that gets a listing suppressed.

The compliance check flags the background independently of the shadow, so you can run it either way - but if the checklist shows the background failing on Amazon, the first thing to try is processing again with the shadow off and the coverage at 85%.

Touching up the cutout

If the automatic cutout leaves a halo of background or bites into the product, press Touch up on any result. A modal opens with the cutout at full size; choose Erase background to paint away leftover pixels, or Restore product to paint back in pixels that the mask wrongly removed. The brush size slider controls the brush diameter. Press Apply and re-render to commit the edit and rebuild the marketplace canvas from the corrected mask.

For a deeper background removal on an arbitrary photo, the smart background remover uses the same on-device segmentation stack. For outputting every marketplace size from one photo at once, use the Product Listing Pack.

Privacy and how detection stays local

Nothing in this tool uploads a photo. The file is read into an Image object in memory, the cutout mask is computed by a local canvas routine, the marketplace canvas is drawn in an offscreen canvas, and the result is exported as a Blob that you download. The compliance check reads pixels from the already-rendered canvas. After the page loads you could disconnect from the network and the whole batch would still finish. The rule library is a static JSON file that ships with the site; thresholds are re-checked against each platform's public seller guidance.
