Frequently Asked Questions
Are my images uploaded to a server?
No. The image compressor uses your browser's Canvas API to resize and re-encode images locally. Files never leave your device.
Which image formats are supported?
JPG/JPEG, PNG and WebP are supported as input. Output is JPEG by default for the best compression on photos.
Will the quality drop?
You control quality with the slider. Anywhere from 70–80% usually keeps images visually identical while drastically reducing file size.
Can I compress multiple images at once?
Yes — drop several files into the upload area and they will all be compressed and made available to download individually.
