Frequently Asked Questions
Does this upload my images?
No. Everything runs in your browser using the Canvas API. Your images never leave your device.
How much will it reduce the file?
Typically 40-70% for JPGs at quality 75%. PNGs compress less because they're already lossless. WebP gives the best ratio.
Will quality be lost?
At quality 75-85% the difference is barely visible. Below 50% you'll see compression artifacts. PNGs can be converted to WebP for lossless compression with smaller file size.
Can I compress many at once?
Yes. Select multiple files and they'll all be compressed in batch and downloaded as separate files.
