01How to compress an image
Choose a simple preset or fine-tune the result.

- 2Choose high quality, balanced, smallest size, custom quality or a target size.
- 3Run compression and compare dimensions, bytes saved and visual quality.
- 4Download the results you want to keep.
02How image compression works
The tool re-encodes supported images and can use repeated quality adjustments to approach a target size.
- JPG, PNG or WebP image
- JPG, PNG, WEBP
→- Optimized image in a supported format
- JPG, PNG, WEBP
- Exact target size cannot always be guaranteed without unacceptable quality loss.
- Already optimized images may show little or no reduction.
03Good reasons to compress
Smaller images upload faster and use less storage and bandwidth.
- Meeting a 500 KB, 1 MB or 2 MB upload limit.
- Speeding up web pages and email attachments.
- Reducing a batch of photos before sharing or archiving copies.
04Start balanced, then inspect
The best setting depends on image content and display size.
- Check faces, gradients, text and fine patterns at 100% zoom.
- If a target cannot be reached cleanly, resize the dimensions before compressing again.
Compression without server storage
Images are compressed in your browser and are not placed in an upload queue.
- Processing time and capacity depend on your device.
- No image name or content is included in optional usage measurements.
