FAQ
Frequently asked questions
How can I compress an image online?
Choose one or more JPG, PNG or WebP files, select a preset and process them. Download each result or one ZIP.
Does compression reduce image quality?
JPG and WebP can trade some visual detail for a smaller file. PNG optimization is lossless unless you resize it or convert it.
Are my images uploaded?
No. Decoding, resizing and encoding happen locally in your browser.
Can I compress several images?
Yes. You can process up to 20 images and 100 MB per batch.
