Frequently asked questions
How does Utilix hit an exact 20KB or 50KB limit?
Instead of guessing a single quality percentage, Utilix runs an 8-step binary search across JPEG quantization levels in browser RAM until the output Blob is strictly below your target KB.
Are my passport or visa photos uploaded to any server?
Never. Identity photos and signatures are processed strictly inside your local browser memory.
Does compressing strip heavy EXIF camera thumbnails?
Yes, Canvas re-encoding automatically drops bloated embedded camera previews and ICC profiles so more bytes go toward visible sharpness.
Can I compress PNG and WebP files too?
Yes, any PNG, WebP, or JPEG input is accepted and optimized.
How many photos can I compress at once?
You can drop 10, 20, or 50+ photos simultaneously and download them all as a single ZIP.
