Make a background transparent

Click the colour you want gone. The eraser spreads from that spot until it reaches a different colour, and the tolerance slider decides how strict that's.

How to make a background transparent

  1. Drop an image in the box above, then click the colour you want to remove.
  2. Adjust the tolerance slider. Higher tolerance erases a wider range of similar shades, and your last click updates live while you drag it.
  3. Undo any click if you go too far, then download as PNG or WebP to keep the transparency.

How the transparent background tool works

The eraser works like a magic wand. It starts at the pixel you clicked and spreads to neighbouring pixels of similar colour, stopping when it reaches something different. That makes it precise on logos, scans, screenshots and product photos with a plain background.

Export as PNG or WebP to keep the transparency. JPG can't store it, so it fills the cleared areas with the colour you pick in the download bar.

Common questions

Is the transparent tool free?

Yes, properly free. No paid tier, no trial, no watermark on the result and nothing to sign up for. Put as many files through it as you like, as often as you like.

Are my files uploaded to a server?

No. The transparent tool runs inside your browser, on your own machine, so your files never go anywhere. Big ones are fine too, up to whatever your browser can hold.

How do I remove a white background from an image?

Click anywhere on the white and the eraser spreads out from that point, taking every neighbouring pixel close enough in colour until it meets something different. Raise the tolerance if patches of off white survive, and lower it if the eraser eats into your subject. Then download as PNG or WebP, since those keep the transparency.

Why are there rough or coloured edges left around my subject?

The edge pixels are a blend of the subject and the old background, so they're neither one colour nor the other. A higher tolerance takes more of them but starts biting into the subject. This works best on flat, even backgrounds like a logo or a product shot on white. A photo of a person against a busy background is a job for a proper cut out.
