Frequently asked questions
How much can an image be compressed?
Photos typically shrink 50–80% at quality 70 with barely visible difference. Screenshots with text compress less.
What output format do I get?
JPEG for photos (smallest), or WebP if your browser supports it. PNG input with transparency is converted to JPEG on a white background.
Can I compress images on my phone?
Yes, it works in any modern browser, mobile or desktop.
Are my images uploaded to a server?
No. Compression happens in your browser using the built-in canvas engine.
