About Negato

Fast, private, free image tools that run entirely in your browser.

Why we built this

Negato (from negate — to flip to the opposite) started with a simple annoyance: reversing the colors of a picture should take one second, yet the popular online tools bury the upload button under ads, slap watermarks on the download, or make you wait for a heavy JavaScript app to boot.

So we built the opposite. Every tool on this site loads as a lightweight static page, works the moment it appears, and does all the pixel work locally with HTML5 Canvas. Your image never touches a server — there is nothing to leak, nothing to store, and nothing to pay for.

What you get

Invert Image — full negatives, per-channel RGB inversion and inverted grayscale.
Flip Image — horizontal and vertical mirrors plus 90° / 180° rotation.
Edit PNG Colors — replace, remove, fill and invert with transparency preserved.

Everything is free, unlimited and watermark-free. More tools are on the way.
