What it does
Inverting is the quickest way to reuse a white-background diagram in dark mode. Adjust the intensity for a softer effect, and keep transparency intact for PNG graphics.
Turn light diagrams dark and dark graphics light with an adjustable inversion.
How to use it
Here is the short version of using Invert Image Colors.
- Open the image — Screenshots and diagrams usually invert best.
- Set the amount — 100% is a full negative; lower values give a muted, stylised result.
- Download the PNG — The output keeps the original dimensions and transparency.
Features that matter
What Invert Image Colors does well.
- Nothing leaves your device — The work happens in your browser tab. There is no upload endpoint in this app, so your files and text cannot be stored, logged or seen by us.
- No upload wait — You skip the round trip to a server entirely. Results are limited by your own CPU, not by network speed or queue size.
- Free, no account, no quotas — No sign-up wall, no watermark, no daily limit. Optional accounts only exist to save favourites and presets across devices.
Frequently asked questions
Is my image safe to use here?
Yes. This tool runs entirely in your browser using JavaScript. Nothing you paste or open is sent to a server, and the page keeps no copy after you close it.
Do I need to create an account?
No. Every tool is fully usable without signing in. An account only adds saved favourites and reusable presets.
Does it work on a phone?
Yes. The interface is mobile-first with large touch targets and a stacked layout, so it works on phones and tablets as well as desktops.
Why do photos look strange when inverted?
Inversion flips every colour channel, so skin tones become cyan and skies turn orange. It works best for black-and-white diagrams, icons and screenshots.
Does inversion affect transparency?
No. Only the RGB channels change; the alpha channel is preserved, so transparent PNG areas stay transparent.
