Frequently asked questions
How do I compress images for free?
Drop your images (JPG, PNG, or WebP) into the tool above, choose an output format, adjust the quality slider, and click Compress Images. Download your smaller files instantly — no account needed.
What image formats can I compress?
You can compress JPG (JPEG), PNG, and WebP images. You can also convert between formats during compression — for example, compress a PNG and save as WebP for even smaller sizes.
Are my images uploaded to a server?
No. All image compression happens entirely in your browser using JavaScript. Your images never leave your device.
Can I compress multiple images at once?
Yes. You can batch compress up to 30 images at a time (up to 500MB total). All compressed images download together as a ZIP file.
How does the quality slider work?
The quality slider (10%–100%) controls the compression level. Lower values produce smaller files with more quality loss. For most uses, 60–80% offers a good balance between file size and visual quality.
