Add a White Background to an Image
Put a product photo on pure white #FFFFFF — the frame Amazon, eBay, and Walmart require for the main listing image. Transparent PNGs land on white instead of black, with padding and an optional 1:1 square frame. No upload, no watermark, no signup.

Need a better photo first?
Compositing on white works on a shot you already have. If the original is cluttered or on the wrong backdrop, ShotKit generates a studio-quality scene from one upload — already on clean white.

Why a pure white background matters
Amazon, eBay, and Walmart all require the primary product image to sit on pure white — RGB 255, 255, 255 — with the product filling most of the frame and no borders, watermarks, or props. The reason is visual consistency: when millions of listings share the same white backdrop, the marketplace grid reads as one clean catalog instead of a patchwork of studio styles. A listing whose main image is off-white, gray, or has a shadow behind the product can be suppressed in search or rejected at upload, even if the product itself is perfectly photographed.
This tool produces that exact frame in one step. Set the background to Pure white, add a little padding so the product does not touch the edge, optionally toggle the 1:1 square canvas for the main-image aspect ratio, and download. The composite runs on an HTML canvas inside your browser, so the background is mathematically pure white — not whatever white your editor happens to export.
Transparent PNG to white, the safe way
A transparent PNG has no background — the areas around the product are empty alpha. If you flatten that PNG to a JPG the naive way, the empty pixels usually fill with black, because JPG has no alpha channel and most tools substitute zero for missing color data. That is how a clean cut-out becomes a product floating on a black rectangle overnight.
This tool paints the white layer first and composites your product on top, so transparency becomes white by construction — there is no code path that lets alpha turn into black. Pair it with the Background Remover to cut the product out of its original scene, then bring the cut-out here to place it on a clean white frame for the marketplace. Both run in your browser; nothing is uploaded.
Frequently asked questions
How do I add a white background to an image for free?▾
Load the photo here, leave the background set to Pure white, and click Composite on background. The tool draws your image onto an HTML canvas that has already been filled with white, then re-encodes it as a fresh JPG, PNG, or WEBP. Anything that was transparent in the source — the checkerboard areas around a cut-out — becomes pure white in the download, never black. Nothing is uploaded; the entire composite runs inside your browser.
Why does Amazon require a white background for the main product image?▾
Amazon's main image rule is that the product sits on a pure white background (RGB 255, 255, 255), with the product filling roughly 85% of the frame and no props, text, or logos. The white backdrop is what makes the marketplace grid look clean and consistent across millions of listings — when every main image is on white, the catalog reads as a single catalog instead of a patchwork. eBay and Walmart apply the same white-background convention to their primary images. This tool gives you that exact frame in one step.
How do I turn a transparent PNG into a white-background JPG?▾
A transparent PNG has no background at all — the areas around the product are empty alpha. If you save that PNG as a JPG directly, the empty areas usually go black, because JPG has no alpha channel and most editors fill missing pixels with zero. This tool avoids that by painting a white layer first, then compositing your product on top, then exporting as JPG. The result is a clean white background with the product exactly where you placed it.
What does the padding slider and square canvas option do?▾
Padding adds a margin of white around the product, as a percentage of the image's long side — useful because marketplaces reject images where the product touches the edge. The Square canvas toggle forces the output to a 1:1 frame, centering the product on white, which is the aspect ratio Amazon and eBay expect for the main listing image. Together they let you take a cut-out of any dimensions and deliver a marketplace-ready square on white.
Is this white-background tool free with no upload or watermark?▾
Yes. The compositing runs entirely in your browser on an HTML canvas — your photo never leaves your device, there is no account to create, no server upload, and no watermark is added to the output. It is free for unlimited use on Amazon, Etsy, Shopify, eBay, Walmart, Instagram, and Pinterest product images.
Need the whole scene shot on white?
Compositing works on a photo you already have. If the original is cluttered or on the wrong backdrop, ShotKit generates a studio-quality product scene from one upload — already on clean white, lit, and marketplace-ready.
