How privacy worksHow it works
Choose an image and a maximum size. Enable smaller dimensions if needed, then process. A successful result is verified to be at or below your limit.
Supported formats
Static JPEG, PNG, and WebP where supported. Animated images, SVG, GIF, HEIC, and AVIF are outside this release.
Good to know
Some targets cannot be met within safe quality, dimensions, and processing limits. Best-effort previews are clearly marked as unmet.
EXIF orientation is applied. Re-encoding may remove metadata and change color rendering. JPEG uses the selected solid background for transparency. Safety limits: 20 MB per image, 24 megapixels, and 8,192 px per side.
A useful answer
Does 50 KB mean exactly 50,000 bytes?
It means no more than 50,000 bytes. Justility uses decimal units: 1 KB is 1,000 bytes. No filler bytes are added.
Can I use this without an internet connection?
Yes, after you prepare the image tools below and the browser retains their assets. Installation is optional. All processing dependencies are bundled locally.
A little less internet. A lot more freedom.
Prepare once. Keep creating, even without a connection.
Only public application assets are cached. Your images stay out of the cache.
