JPG, PNG, WebP supported — reduced size, same quality
What is image compression?
Image compression reduces the file size of an image while keeping it visually similar to the original. This makes images faster to load on websites, easier to email, and cheaper to store.
How to use this tool
- Drag and drop your image, or click to browse.
- Adjust the quality slider (75% is a good starting point).
- Optionally set max width/height to resize.
- Choose output format (JPEG, WebP, or keep original).
- Click Compress Image and download the result.
Which format should I use?
- JPEG: Universal compatibility, good for photos.
- WebP: 25-35% smaller than JPEG at same quality, supported in all modern browsers.
- Keep original: If you need lossless PNG output or transparency preserved.
Tips for best results
- For web use, aim for under 200 KB per image.
- Combine compression with resizing if the image is larger than displayed size.
- Preview the result before deleting your original.
Privacy
Images are processed locally in your browser. Nothing is uploaded to any server. EXIF metadata is stripped during compression.
Frequently Asked Questions
Is this Image Compressor free?
Yes, completely free. No signup, no watermarks, no limits.
Are my images uploaded to a server?
No. Compression happens entirely in your browser using the Canvas API. Your images never leave your device.
How much can I reduce image size?
Results vary by image. Photos usually shrink 40-80% at quality 0.7-0.8 with no visible loss. WebP format can reduce size even further.
What quality should I use?
For web: 75-85%. For sharing: 70-80%. For maximum compression: 50-60%. Below 50% becomes visibly degraded.
Should I use WebP?
WebP gives 25-35% smaller files than JPEG at the same quality. Modern browsers all support it. Use it unless you need maximum compatibility.
Does compression remove metadata (EXIF)?
Yes. Canvas-based compression strips EXIF metadata (camera, GPS location, etc.). This is usually a privacy benefit.
