Frequently Asked Questions

Is this compressor really free?

Yes. No limits, accounts, or watermarks. Your CPU does the work in the browser.

Are my photos private?

Yes. Files never leave your device, so we cannot access them.

What does before / after mean?

Before is the original file size. After is the new JPEG size at your chosen quality β€” shown on each row.

Why JPG output for PNG uploads?

JPEG gives strong size control via the quality slider. PNG lossless compression in-browser rarely shrinks photos much.

Will I ruin print quality?

At high quality (90–100%) changes are usually invisible on screen. For print, keep quality high or keep originals.
