Before/After Image Comparison
Slider between original and a light enhance, or two uploaded frames.
Before/After Image Comparison is its own job in the catalog (utilities): Slider between original and a light enhance, or two uploaded frames. It is not a copy of the resizer or converter with a new title — the operation is “before-after”.

Questions about this tool
Does Before/After Image Comparison 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 Before/After Image Comparison 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.
