Benefits
Private by design
Your image stays on your device while Image Saturation works. Image Saturation never sends it to a server, so confidential work stays confidential.

There is no upload step, so Image Saturation starts the moment you add your image.
No signup, no limits
Use Image Saturation as many times as you want. Image Saturation asks for no account, adds no watermark and keeps no paid tier gating the output.
Works offline
Once the page has loaded, Image Saturation keeps working without a connection, which helps on flights and locked-down networks.
Who it is for

How it works
Image Saturation loads your image into memory, applies the change you requested to the underlying data rather than to a screenshot of it, and writes a fresh copy for download. Your original stays untouched on disk, and every step of Image Saturation happens inside your browser sandbox.
Frequently asked questions
Is Image Saturation free to use?
Yes. Image Saturation is completely free with no account, no trial and no usage cap. Every feature on this page is available on the first visit.
Does Image Saturation upload your image to a server?
No. Image Saturation processes your image inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.
Is there a file size limit?
The practical ceiling is your device's available memory rather than a server quota. Files up to roughly 100 MB work comfortably on a typical laptop in Image Saturation.
Do I need to install anything to use Image Saturation?
No installation is needed. Image Saturation runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Image Saturation on a phone or tablet?
Yes. The Image Saturation interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
What happens to your image when I close the tab?
It is discarded. Image Saturation keeps everything in temporary browser memory, so closing the tab removes every trace of the session.
