Paint over the area you want to remove with an eraser brush. This is manual editing; it does not automatically detect a subject.
Choose a JPG, PNG or WebP. Large images are reduced so the longest side is at most 1400 pixels in the editing canvas.
Choose a brush size and paint over the background. Use Restore for areas erased by mistake or Undo for a previous stroke.
Inspect the edges and save the -cutout.png copy. Transparency is preserved; this tool does not add a replacement background.
Use a larger brush away from the subject and a smaller one near hair, lettering and corners. Check the edge against the transparency grid. A manual brush cannot infer detail hidden behind the background.
The result has the editing canvas dimensions, so a large original may produce a smaller PNG. Keep the original for high-resolution printing. If you need a white background later, converting the cutout to JPG fills transparency with white.
No. You paint away pixels manually.
No. The work happens inside this tab, on your own machine. Open your browser's network tab while you use the tool, there is no request carrying your file.
Practical limits depend on the tool, browser and available device memory. Large files can fail even when no explicit limit is shown. Keep an original and use a smaller job if this device cannot finish it.
No, and there is no daily limit either. There is nothing to sign up for.
You paint over the parts you want to remove and they become transparent. There is no automatic detection of the subject, which is deliberate: you decide exactly what stays. The Put it back option restores the original pixels where you rubbed out too much, and you can undo your last dozen or so strokes.
Work with a large brush for big areas and a small one near edges. A photo with a plain, contrasting background is far quicker to cut out than a busy one.
The working copy is limited to 1400 pixels on its longest side, so a larger photo is saved at that size. The result is a PNG with transparency, which can be placed over any colour or picture.
The brush has a hard edge, so it is not suited to fine hair or fur, where an automatic tool would do better. For a passport style photo, cut the background out here, then bring the PNG into Passport photo and choose a white or light blue background.
