What every platform actually demands
Checked against Allegro's seller rules, Amazon Seller Central guidance, eBay's picture policy and Etsy's help centre in July 2026. Every preset in the tool is built to hit these numbers exactly, so you tick a box instead of reading a rulebook. Platforms revise specs, so confirm before a very large upload.
| Preset | Background | Size and format | The rule behind it | Ours |
|---|---|---|---|---|
| Allegro 2560 white | Pure white 255,255,255 | 2560 x 2560, JPEG, sRGB | Thumbnails must be uniform white 255,255,255, no border, no text, no logo. Longer side 400 to 2560 px, up to 26 Mpx. Bigger files get downscaled by Allegro, which costs sharpness, so 2560 is the sharpest legal size. | exact |
| Allegro 1600 white | Pure white 255,255,255 | 1600 x 1600, JPEG, sRGB | Same rule, smaller file. Useful on slow connections or for bulk API uploads. | exact |
| Allegro fashion grey | Light grey #EBEBEB | 2560 x 2560, JPEG, sRGB | Allegro allows uniform light grey instead of white only in selected Fashion, Kids and Sport subcategories, and defines it in HSV with brightness V of at least 0.8. Our grey sits at V = 0.92, comfortably inside the rule. | exact |
| Amazon 2000 white | Pure white 255,255,255 | 2000 x 2000, JPEG, sRGB | The strictest of them all. The main image must be pure white AND the product must fill at least 85 percent of the frame, or Amazon suppresses the listing. Zoom needs 1000 px minimum, 1600 to 2000+ recommended, 10 MB cap. Our default padding fills 86 percent. | exact |
| eBay 1600 white | White, recommended not forced | 1600 x 1600, JPEG | eBay does not force white but recommends white or light grey and rewards it in search. 500 px is the minimum, 1600 px is the exact threshold where desktop zoom switches on, 12 MB cap. No borders, text or watermarks. | exact |
| Etsy 2000 white | White, recommended | 2000 x 2000, JPEG | Etsy recommends at least 2000 px and a square 1:1 crop, and the first photo must be at least 635 px or the listing ranks lower. Etsy is the one place where lifestyle shots often beat studio white, so use white for clarity and lifestyle in slots 2 and up. | exact |
| Instagram 1080 | White | 1080 x 1080, JPEG | The native square feed size. Anything larger gets recompressed by Instagram, which softens edges. | exact |
| Facebook 1200x630 | White | 1200 x 630, JPEG | The link and ad preview ratio, 1.91:1. Product centred so nothing important is cropped on mobile. | exact |
| YouTube 1280x720 | White | 1280 x 720, JPEG | The standard 16:9 thumbnail size. | exact |
| Transparent PNG | None, alpha channel | Original size, PNG | For designers, banners and A+ content. Not for an Allegro or Amazon main photo: both want white behind the product, not transparency. | exact |
| Custom | White | Your pixels, JPEG | Any size from 100 to 4000 px, for shops that ask for something odd. | exact |
The two numbers that get listings punished
255,255,255. A photo shot in a cheap light tent is never pure white; it is grey or faintly blue, and the automated check sees it even when your eye does not. Removing the background and painting true white is the only reliable way to hit the value exactly.
85 percent. Amazon requires the product to fill at least 85 percent of the frame. Most sellers leave far too much empty margin, which also makes the thumbnail look weak next to competitors. The padding slider here defaults to a fill of 86 percent, which clears Amazon and still looks composed on Allegro.
One more thing nobody warns you about: some privacy browsers add tiny random noise to images created inside the browser, which pushes a perfect white down to 254 with no visible change at all. If yours does that, RemovalForge detects it and tells you, because near-white is exactly what these rules reject.
