Image Colorizer
Applies a warm colour grade to grayscale. Not historical ML colourization.
Image Colorizer is its own job in the catalog (photo): Applies a warm colour grade to grayscale. Not historical ML colourization. It is not a copy of the resizer or converter with a new title — the operation is “colorize”.

Image Colorizer runs in this browser with Canvas. The file is not uploaded to imagecropx. Close the tab and the copy in memory is gone.
What this is not
Canvas filters are not a cloud “AI restore.” Faded scans can look a bit cleaner; missing corners are not invented.

Questions about this tool
Is this a neural model?
No. These tools use canvas filters. Quality is honest, not a cloud model.
Does Image Colorizer upload my file?
No. Processing is in this browser.
Can I use this on a phone?
Yes, with the same file-size cap (about 25 MB). A large photo is slower on a phone CPU than on a laptop.
Does Image Colorizer upload the file?
No. This tool runs in the tab. See Privacy for decoder notes (HEIC, PDF.js worker).
What is the file size cap?
About 25 MB per file. Very large pixel counts are rejected so the tab stays responsive.
