Browse FilesReduce image file size without leaving the browser
This tool redraws your image locally and exports a smaller copy in the format you choose. It is useful when you want to shrink web assets, email attachments, or upload-ready files without handing the image to a server.
Benefits: Pick JPG, WebP, AVIF, or PNG, tune the quality slider, batch multiple files, and keep processing on your device.
Best for: Website assets, email attachments, upload limits, and files that need to be smaller before publishing or sharing.
Limitations and tradeoffs
- PNG output is lossless, so size reduction can be limited compared with JPG, WebP, or AVIF.
- Animated image formats are flattened to a single exported frame through the browser canvas.
- Very large batches can take time because every file is processed on your device.

Which output format should I use?
Choose JPG for photos, WebP for smaller web-ready files, AVIF for aggressive modern compression, and PNG when transparency matters.
Will compression happen on a server?
No. The image is processed locally in your browser and the result stays on your device until you download it.
Can I compress multiple images at once?
Yes. Add a batch of images, pick a target format and quality, and download the results individually or as a ZIP.
