Remove the background from an image, with no upload
To remove the background from an image, drop it into the box above: the tool takes the colour that appears most in the corners, treats it as the background and makes it transparent at once, working inwards from the edges. If the result is not right, click another part of the background with the picker, raise the tolerance step by step (10% by default, 20 to 30% for an unevenly lit background), brush away leftover shadows with the eraser, then download a transparent PNG or a JPG on pure white. A product photo taken on a sheet of white paper is done in under a minute, at up to 3,000 pixels on the long side. The image never leaves your device: your browser does all the work, which also means nothing is stored on a server. The main limit comes from the method: the tool works by colour and does not recognise the subject, so a portrait with loose hair in front of a busy room will not come out clean.
What it does well, and what it cannot do
Colour-based cut-out turns pixels close to the background colour transparent, within the tolerance you set. It is quick and precise whenever the background stands apart from the subject: an item photographed on white or on a plain colour for a Leboncoin or Vinted listing, a logo or icon you want to place on a website, a signature or company stamp scanned on white paper, a screenshot or a flat illustration, or a photo taken in front of a well-lit wall, sheet or green screen, with a few touch-ups.
The tool does not know what the subject is. It is not meant for a person with loose hair, a long-haired animal, a tree, or a street or living-room photo where the background mixes dozens of colours. Those cases need an AI cut-out: the models that can do it weigh tens of megabytes and usually run on a server, which means sending your photo there. Here, the image stays with you.
Four steps
1. Pick the background colour. On opening, the tool uses the most common corner colour, usually the background. If it guessed wrong, keep the picker selected and click the background itself.
2. Set the tolerance. Too low and patches of background remain, especially where the light changes; too high and the tool starts eating into the subject. Raise it a little at a time while watching the checkerboard preview, then check on black, where light halos show up best.
3. Touch up by hand. The eraser removes a cast shadow or reflection that colour alone cannot separate; the Restore brush paints back what was removed by mistake. On a phone your finger is the brush, and "Undo last stroke" fixes a slip.
4. Download. The PNG keeps the transparency; "JPG on white" gives a pure white background, which many marketplaces ask for. To make the file lighter afterwards, use resize an image.
Getting a good starting photo
The result depends mostly on the photo. Put the subject in front of a plain, matt background, about a metre away from it if you can, to avoid cast shadows. Light the background evenly, with daylight near a window or two lamps on either side. Choose a background colour that the subject does not contain: white behind a dark object, dark or coloured behind a white one.
For a signature, use a black or dark blue pen on white paper and photograph it flat, with no shadow from your hand or phone. The PNG can then go onto a French lease, quote or form with the sign PDF tool, or become the starting point of a logo.
Frequently asked questions
I sell on Leboncoin or Vinted, can I get product photos on a white background?
Yes, as long as the photo was taken on a fairly plain surface such as paper, a sheet or a light wall. One click on that colour makes it transparent, then the "JPG on white" button gives a pure white background that listings and marketplaces like. Shadows cast by the object sometimes remain: brush them away with the eraser. For a white object on white, lower the tolerance and keep the edge mode.
Why do hair and fur keep a halo of the old background?
The tool decides pixel by pixel from colour alone. Fine strands mixed with the background have an in-between colour, neither quite background nor quite subject, and the tool does not recognise a person or an animal the way AI cut-out services do. The edge softening setting reduces the halo, but a portrait with loose hair in front of a busy room will never come out clean here.
How do I turn a scanned signature into a transparent PNG for French paperwork?
Sign on plain white paper with a dark pen, photograph it flat in good light and open the image. Choose "Whole colour" so the inside of the loops turns transparent too, and raise the tolerance until the paper grain disappears. Tick "Crop to content" and download the PNG. You can then place it on a lease, a quote or a sworn statement with the sign PDF tool.
The PNG shows a black background when I open it, did the transparency get lost?
No. The image viewer paints something behind transparent areas, often black, white or a checkerboard. Drop the PNG onto a coloured slide or web page to check. Transparency is only lost when you download the JPG, a format with no alpha channel, or when a messaging app converts the file to JPEG while sending it. Send the PNG as a file or by email instead.
My photo is 4,000 pixels wide, why is the downloaded PNG smaller?
The tool works on the image at 3,000 pixels on its long side at most, so the eraser and restore brush stay smooth even on a phone. The original size and the working size both appear under the preview. 3,000 pixels is plenty for a product listing, a website or an A5 print. For a poster, cut out the image in desktop photo-editing software instead.
