Before you start

GIMP is a free photo editor for Windows, Mac and Linux. At the time of writing the newest stable version is GIMP 3.2; the menu names below follow the official GIMP 3 manual. You need one thing first: an alpha channel, which is what lets a layer be see-through.

Method 1: Fuzzy Select (plain or one-colour background)

1. Open your photo with File → Open.
2. Choose Layer → Transparency → Add Alpha Channel. (If it is greyed out, the layer already has one.)
3. Pick Tools → Selection Tools → Fuzzy Select and click the background. Hold Shift and click to add more areas.
4. Raise or lower Threshold in the tool options if the selection spills into the product or misses parts of the background.
5. Press Delete. The background turns into a grey-and-white checkerboard — that means it is transparent.
6. Choose File → Export As, name the file with .png at the end and export.

Method 2: Foreground Select (busy backgrounds, people, pets)

1. Add the alpha channel as above.
2. Choose Tools → Selection Tools → Foreground Select and draw a rough line around the subject, then press Enter.
3. Paint over the subject with the foreground brush. Paint hair, gaps or the background with the background brush to correct it.
4. Press Enter to turn it into a selection, then Select → Invert so the background is selected.
5. Press Delete and export as PNG.

The quick way when you only need the cut-out

GIMP gives you full control, but a careful Foreground Select can take a few minutes per photo. If you just need a clean product photo, a logo or a profile picture, drop the image into rmvbg: the background is removed automatically on your own device, and you can download a transparent PNG, put it on white for a marketplace or change the background colour. Many people do the rough cut in rmvbg and only open GIMP for fine retouching.
