About inverting colours here

Every pixel flips to its opposite. Black turns white, blue turns orange, light turns dark. It's the same look as an old film negative.

Inverting is exact and loses nothing. Run it twice and you get your original image back. That also means it can turn a scanned negative into a normal photo.

Common questions

Is the invert 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 invert 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.

What is inverting an image used for?

Reading a scanned negative, turning white on black diagrams into black on white so they print without eating a cartridge, checking a design against a dark background, and the occasional visual effect. It's also a quick way to see detail hidden in a very dark or very bright area, since the eye reads the flipped version differently.

Does inverting twice give me the original back?

Yes. Every colour is swapped for its exact opposite, so doing it a second time lands on precisely the values you started with. Nothing is estimated or thrown away. Just download as PNG rather than JPG if you're going to invert repeatedly, so the compression doesn't build up.
