About the Adjust Image Saturation
Each pixel is pushed away from - or towards - its own luminance, which changes colour intensity without changing brightness.
At -100 the image is fully greyscale, which is another route to the same result as the greyscale tool.
Questions people ask
Is your image uploaded to a server?
No. This tool runs entirely in your browser using standard web APIs, so your image never leaves your device. You can confirm it by opening your browser's network panel while the tool runs, or by disconnecting from the internet after the page has loaded.
Is it free, and do I need an account?
Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
