Remove Background cuts a subject out of a plain backdrop by colour, in your browser. It reads the background from the picture's edges or a colour you pick, feathers the edge 0 to 5 pixels, and saves a transparent PNG.
Reads the colours along the four edges of the picture, groups them into up to three background colours (or uses one you pick on the photo), and makes the matching area connected to the edges transparent, so a white shirt on a white wall stays whole. Switch off Only from the edges to remove every matching pixel. It is a colour-key cut-out, not a machine-learning one: it works well when the subject sits on a plain, evenly lit backdrop such as a product shot, a logo on white, a sticker on a green screen or a document photo, and it cannot separate a person from a busy street. The edge of the cut can be feathered, and the removed area can stay transparent, be filled with a flat colour, or show a blurred copy of the original scene.
Because it works by colour rather than by recognising objects, the result is predictable: the same settings give the same cut every time, which matters when you process a set of product photos and want them to match. The photo never leaves your device.
A 2000 × 2000 photo of a coffee mug on a white tabletop: with Sensitivity 35 and Colour range 50 the white goes away in one pass, and Edge softness 2 hides the halo around the handle. Saved as PNG the cut-out is about 1.1 MB; as WebP at quality 90 it is around 240 KB and still transparent. A black logo scanned from paper needs Sensitivity 20 and softness 0 so the thin strokes stay crisp. A subject photographed against a green sheet with folds needs Colour range 80 so the darker creases still count as background.
Those three cases are what the preset buttons hold:
| Preset | Sensitivity | Colour range | Edge softness | Good for |
|---|---|---|---|---|
| Logo on white | 20 | 30 | 0 px | Logos, signatures, line art, scans |
| Product photo | 35 | 50 | 2 px | Objects on a white or grey sweep |
| Green screen | 60 | 80 | 2 px | Unevenly lit green or blue backdrops |
The default, used when you first open the tool, is Sensitivity 30, Colour range 50 and Edge softness 2 px with Only from the edges switched on.
Use it for product photos, logos, stickers, screenshots of a chart on a flat colour, or anything on a green screen. Skip it for portraits against a room, landscapes and group photos; the background there is not one colour and the result will have holes. If the subject touches the edge of the frame, the tool may read the subject as background, so crop a little air around it first with Crop Image, or switch Colour to remove to Choose and pick the backdrop yourself.
After the cut, Round Corner or Clip Image can shape the transparent canvas, and Add Text can drop the result onto a caption. For an ID photo on white, finish in Passport Photo Maker. If you only want the background to stand back rather than disappear, Blur mode here, or Blur Image for the whole picture, may be all you need.
The Background section starts with three choices for what replaces it. Transparent cuts it out and switches the output to PNG. Colour fills the removed area, useful for putting a product on a brand colour. Blur keeps the scene but softens it, with a radius from 2 to 60 px (16 by default).
Colour to remove is Auto from edges, which reads up to three colours from the picture’s border, or Choose, where you set the colour by hand or press Pick the background and click it on the photo. Only from the edges, on by default, removes only matching pixels connected to the border; switch it off to also clear gaps inside the subject, such as the hole in a mug handle.
Sensitivity (10 to 100) is how far a pixel may be from a background colour and still be removed; raise it when specks of background remain, lower it when parts of the subject vanish. Colour range (20 to 100) controls how the edge samples are grouped into background colours; wider handles gradients and uneven light, narrower protects a subject that shares a tone with the backdrop. Edge softness feathers the cut in pixels: 0 for logos and pixel art, 1 to 2 for photos, up to 5 for hair-like edges.
Transparent output needs PNG, WebP or AVIF; JPEG fills transparency with the Background colour in the Output section.
Why did part of my subject disappear? It shares a colour with the backdrop. Lower Sensitivity first, then narrow the Colour range. If a white shirt sits on a white wall, no colour-based cut can tell them apart; photograph it on a contrasting sheet.
There is a thin outline left around the edge. How do I remove it? Raise Sensitivity by 5 to 10 and set Edge softness to 1 or 2. The outline is the anti-aliased mix of subject and background colour along the boundary.
Can it remove the background from a portrait? Only when the person is in front of a plain wall or a green screen. Real rooms and outdoor scenes contain too many colours for a colour-key cut.
Does the photo get uploaded? No. The cut-out is computed on your device. You can turn off the network after the page loads and it still works.
Why does my download have a white background instead of a transparent one? JPEG cannot store transparency, so the see-through area is filled with the Background colour in Output. Choose PNG, WebP or AVIF to keep it transparent. Picking Transparent switches the output to PNG for you.
How do I make the background white for a product listing or ID photo? In the Background section, choose Colour and leave the fill on white, or pick any brand colour. For a passport photo, cut the background here and then size the result in Passport Photo Maker.
Can I remove the background from many photos at once? Yes. Drop several files, or turn on Batch mode. Every photo gets the same settings and you download one ZIP, which works well for a set of product shots taken on the same backdrop.
