Frequently asked questions

How do I compress images for free?

Drop your JPG, PNG, or WebP files into the tool above, adjust the output format and quality slider, then click Compress Images. Download individually or as a ZIP.

Are my images uploaded to a server?

No. All compression happens in your browser using JavaScript. Your images never leave your device.

What image formats are supported?

JPG (JPEG), PNG, and WebP. You can compress any combination and choose your output format independently.

Can I compress multiple images at once?

Yes. Drop up to 30 images at a time (500MB total). Each file is compressed individually and you download them as a ZIP.

How does the quality slider work?

Lower quality means smaller file size but more visual compression. 70% is a good default. PNG output ignores the quality setting since PNG is lossless.
