How to use Remove Background

  1. Add your image

    Drop in a photo. Subjects with clear edges against a contrasting background give the best results.

  2. Set the background colour

    By default it samples the top-left corner. If that is not the background, click the eyedropper and click the background itself.

  3. Tune the threshold

    Raise it until the background is gone, lower it before it starts eating the subject. Feathering softens the boundary between the two.

  4. Download as PNG

    Save as PNG to keep the transparency. Saving as JPG fills the transparent area with white.

When to use Remove Background

  • Putting a product photo on a clean white background for a listing
  • Cutting out a person for a composite image or presentation
  • Making a logo transparent so it can sit on any colour
  • Preparing an image for a design where the background would clash

FAQ

By colour distance, on a canvas. One reference colour is sampled — the average of the top-left 5x5 pixels, or the pixel you click with the eyedropper — and every pixel within the threshold distance of it in RGB is made transparent. There is no subject detection, no edge detection and no machine learning involved.
Not really. It needs a background that is one fairly even colour, because that is the only thing it can identify. A busy scene, a gradient, or a subject the same colour as what is behind it will not separate cleanly at any threshold.
Because something along the way re-saved it as JPG, which has no transparency channel. The download from here is always a PNG and keeps the transparency; it is converting it afterwards that loses it.
Because it was close in colour to the background. The tool separates by colour alone, so a white collar against a white wall is indistinguishable from the wall. Lower the threshold, or reshoot against a colour the subject does not contain.
No. It needs a background that is essentially one colour. Photographs taken in real rooms, gradient backdrops and busy scenes are outside what a colour key can do, and no threshold setting rescues them.
Processing runs in your browser, so your images stay on your device — which matters for product photography and personal photos alike.

About Remove Background

This is a colour key, the same idea as a green screen. One reference colour is taken from the image, every pixel is measured against it in RGB space, and anything closer than the threshold becomes transparent. It knows nothing about what is in the picture — only about colour.

That makes it excellent at one job and poor at everything else. A product shot on a plain white sweep, a logo on a solid field, a passport-style photo against a painted wall — all of those key out cleanly. A photo taken in a room, a gradient backdrop, or a subject wearing the same colour as the wall behind them will not, at any threshold, because the tool has no way to tell the two apart.

The output is always a PNG, which is the right choice: transparency only exists in PNG and WebP. If you later convert the cut-out to JPG the transparent region becomes solid white, because JPEG has no concept of an alpha channel.

Tips and limits

  • The download is a PNG. Do not convert it to JPG afterwards — that fills the transparency with white.
  • Any colour the subject shares with the background disappears too — a white shirt against a white wall will be punched through.
  • Use the eyedropper whenever the top-left corner is not the background — the automatic sample assumes it is.
  • For product photos, shooting against a plain sheet beats any amount of post-processing.
  • Transparent PNGs are larger than JPGs. Compress before using them on a web page.
