Add White Background to Photo — Free, Fast & Private
Putting a photo's subject on a plain white background used to be described on this page as a two-step job with a paywall in the middle. It no longer is. Cutting the subject out is free, and so is flattening it onto white: pick White from the palette under the tool above and it hands back a single flattened image, no separate export step. Free tier still means a 1080px ceiling and a small watermark in the corner — that part has not moved — and Pro is where the ceiling lifts, the watermark goes, and the rest of the colour palette opens up.
Transparent PNG and flattened white are different files
They can look identical in a preview and behave completely differently downstream. A transparent PNG stores an alpha channel — the background is absent, and whatever sits under the image shows through. Drop it into a dark-mode app and your "white background photo" is suddenly floating on charcoal. A flattened white image has actual white pixels baked in: it looks the same everywhere, can be saved as a much smaller JPEG (alpha-carrying PNGs of photographs run large — a full-resolution cutout can reach tens of megabytes, where the flattened JPEG is one or two), and is what upload forms that reject PNGs or strip transparency expect. The rule of thumb: keep the transparent version as your working master, because you can put it on any background later; produce the flattened white version for the destination that demands one. Clicking White does the flatten-and-encode as a JPEG in one step, at no cost; skipping that click leaves the transparent PNG sitting there as your master file for whatever comes next.
White is free; the rest of the palette still isn't
Download the cutout, click White, and the flattened JPEG comes back at up to 1080px with a small watermark — no account, no Pro. Black, cream, and coral are still gated, and if you want one of those without upgrading, the old recipe still works exactly as before: take the free transparent cutout and paste it onto your colour of choice in any editor that understands layers. Preview on a Mac or Paint on Windows will do it — create an image filled with your colour and paste the cutout on top. Google Slides or PowerPoint works too: set a slide's background to the colour, place the PNG, export the slide as an image. Canva and Photopea offer the same trick with a coloured frame. Either free path — the White button or the manual paste — draws on the same shared allowance for the cutout itself: 2 AI runs split across the background remover, the upscaler, and the passport tool, after which a cooldown starts at 60 minutes and lengthens by 30 each time the pool empties again.
Where flattened white is actually mandatory
Marketplace listings are the big one — several platforms require or strongly favour a plain white backdrop on primary images, and the specifics matter enough that they get their own page: the white background product photo guide covers Amazon, eBay, and Etsy rules and the batch workflow. Identity photos are the other: passports and visas need a specific background colour and face positioning to a government spec, which is a different pipeline entirely — that lives at the passport photo background change tool. In between sit the everyday cases this page serves: a headshot for a company directory that wants uniform backgrounds, a profile picture where your kitchen was the backdrop, a document photo for an application form, an object you are listing on a local classifieds site that just needs to look clean.
Why the cutout stays on your machine by default
The segmentation model — RMBG-1.4, a 44 MB open model, with a 250 KB instant tier for people — downloads to your browser and runs there via WebGPU. The photo you are whitening is often a photo of you, or your family, or something you have not published yet; on this tool it is decoded, segmented, and re-encoded without a single byte of image data leaving your device — unless you are on Pro and deliberately switch on Cloud HD, in which case that one photo uploads for that one run and is deleted when it finishes. Upload-based background services process the same photo on their servers under whatever retention terms their privacy policy buried on page four. If you want to check the free-tier claim rather than trust it, open your browser's network inspector and watch: after the one-time model download, nothing goes out.
