Background colour
Change your image background color
Swap whatever is behind your subject for a flat colour — pure white for a marketplace listing, a brand shade for a deck, a deep grey for a headshot. The cutout is automatic, the colour is a click or a hex code, and the file comes back at the resolution you started with.

Swatches and hex
Pick a colour, or type the hex you need
Ten swatches cover the fills people reach for most — the neutral ladder for product photography, and the accents for social and ads. Next to them is a colour picker that takes any hex value, so a brand colour goes in exactly as specified rather than approximately.
The fill is applied live to the image on screen at full size, not to a thumbnail, so what you are judging is what you will download.

Anything outside that ten goes in through the custom field as a six-digit hex. There is no palette limit and no premium colour tier — the fill is afillRect on a canvas in your own browser, which costs nobody anything.
Marketplace
The white that marketplaces actually require
“White” is not a judgement call on a product listing. Amazon wants pure white — RGB 255, 255, 255 — and a near-white from a lightbox will not pass. These presets set the fill, the canvas size and the padding together, so the file is to spec without you measuring anything.
| Preset | Canvas | Background | Padding |
|---|---|---|---|
| Amazon | 2000 × 2000 | #FFFFFF | 7% |
| eBay | 1600 × 1600 | #FFFFFF | 5% |
| Shopify | 2048 × 2048 | #FFFFFF | 6% |
| Etsy | 2000 × 2000 | #FFFFFF | 6% |
| Passport | 600 × 600 | #FFFFFF | 8% |
LinkedIn’s 1128 × 1128 preset is in the editor too. It sets the canvas but leaves the fill to you, because a profile photo on pure white reads as a passport document rather than a headshot.
Edges
Why a flat colour shows up every bad edge
A busy replacement background hides a rough cutout. A solid fill does the opposite: the moment the old background was, say, warm beige and the new one is pure white, every pixel that was half beige reads as a grubby outline around the subject. That halo is not a bug in the mask — it is the pixels where the old scene and the subject genuinely mixed.
Four controls deal with it, and none of them re-runs the model, so the picture updates as you drag.
Cutout sensitivity
0 – 100Moves the threshold between subject and background. Raise it when a dark jacket is being eaten; lower it when a pale wall is surviving around the shoulders.
Feather
0 – 12 pxSoftens the matte edge. Half a pixel is enough for a crisp product shot; two or three suits a portrait, where a razor edge is the thing that looks fake.
Shrink / grow
−50 – +50Pulls the matte inwards or pushes it out. Shrinking a few steps is the direct fix for a halo, because it discards the pixels that were half old background to begin with.
Refine brush
4 – 200 pxRestore or erase the matte by hand where the model was wrong — the only thing that reliably rescues wispy hair against a busy backdrop.
The default already leans on this: the matte ships shrunk by six steps, because a hairline of the old background is the single most common complaint about an automatic cutout on a white fill.
Alternatives
When a solid colour isn’t the right answer
A flat fill is right for a catalogue and wrong for a portrait, where it makes the subject look pasted on. Three other options sit next to it in the same panel.
- Gradient
- Two stops drawn corner to corner. Six presets, and the same six are the brand-accent pairs used across this site — useful for ad creative and social, where flat white looks like a mistake.
- Blur
- Keeps the original scene and defocuses it, 2 px to 60 px. This is the honest choice for a headshot: the light on the subject still matches the room behind them, because it is the same room.
- Your own image
- Any PNG, JPG, WebP or AVIF, drawn to cover the frame. It loads from your disk into the same tab, so a background plate stays as private as the photo.
- Nothing at all
- Export a PNG or WebP with a real alpha channel and place it over whatever you like later. JPG has no alpha, so a transparent export saved as JPG lands on white rather than silently going black.

One colour across a whole folder
Changing the background colour of one photo is a minute’s work anywhere. The reason people end up paying for it is the other ninety-nine. Here the queue takes as many files as you drop on it, the background you set applies to all of them, and the finished set downloads as a single ZIP — so a catalogue re-shoot costs the time it takes your laptop to run, and nothing else.
That is a direct consequence of where the work happens. A hosted tool has to charge per image because each one occupies a server; this one runs on hardware you already own, so the hundredth image is free for exactly the same reason the first one is.
The step-by-step guide to changing an image background walks through the whole sequence, and the comparison with remove.bg and Canva has the per-image numbers.
