Frequently Asked Questions
How do I use the invert image colors tool?
Drop your image onto the box above, adjust the controls, and the preview updates as you drag. When it looks right, choose PNG, JPG or WEBP and press Download. Nothing is uploaded at any point.
Are my files uploaded to a server?
No. The file is decoded and re-encoded directly in your browser using JavaScript and WebAssembly, and never leaves your device. That is what makes it safe for private photos, client work and anything confidential, and it is why the tool keeps working with your network disconnected once the page has loaded.
Can I recover the original by inverting twice?
Yes. Inversion is exactly reversible, so inverting the result again returns the original pixels — provided you export losslessly as PNG. Going through JPG each time will slowly degrade the image.
Is there a limit or a watermark?
No limits, no watermark, no signup and no cost. Because the work happens on your own device there is no server bill to cover, so there is nothing to meter — the only real constraint is your device’s memory on very large files.
Does this work on Windows, Mac, iPhone and Android?
Yes. It runs in any modern browser on Windows, Mac, Linux, iPhone and Android with nothing to install and no account needed. Chrome, Edge, Firefox and Safari are all supported.
