Compress images for web, email and storage
Large images can slow pages and make uploads difficult. Use the image compressor to choose a quality level, compare the result and download an optimized copy.
Use the image compressor
Open the free image compressor to process a local image. Your original file stays on your device while you work in the browser.
Tips for smaller image files
- Resize an image when its dimensions are larger than the space where it will be displayed.
- Use JPEG for many photographs and PNG when transparency is important.
- Check the exported image before replacing your original.
