Compress images
Reduce image file sizes with local browser processing. Adjust JPEG and WebP quality, review the output and download images separately or as a ZIP.
Choose images
JPG, static 8-bit PNG and WebP. Up to 20 images, 25 MB and 16 MP each; 100 MB combined.
Your results
Choose your files. Previews and downloads appear after processing.
How it works
- Choose static JPG, PNG or WebP images.
- Adjust quality and start processing. PNG uses lossless re-encoding.
- Compare the result sizes and download individual images or a selected ZIP.
A practical example
Prepare a set of photos for an email. Try a lower quality setting, then check both file sizes and the visible result.
Supported files and limits
Static JPG, 8-bit PNG and WebP. Up to 20 images, 25 MB and 16 megapixels each, 100 MB combined. Animated images and 16-bit PNG are rejected. Re-encoding does not retain metadata or colour profiles. Your original files are unchanged.
Frequently asked questions
Is a smaller file guaranteed?
No. Some files are already efficiently encoded. The result shows size savings or an increase.
Does the quality slider change PNG quality?
No. PNG is re-encoded losslessly. The slider affects JPEG and WebP.
