What is the Image Compressor?
The Image Compressor is a free, client-side tool that reduces image file sizes without a noticeable loss in visual quality. Using smart lossy compression (JPEG) or next-gen WebP conversion, you can shrink images by 50-80% while keeping them sharp. All processing is done locally in your browser — no uploads, no accounts needed.
Why Compress Images?
Faster Page Load Times
Images account for 50-60% of average page weight. Smaller images directly improve load time and Core Web Vitals scores.
Smaller Email Attachments
Stay under email attachment limits by compressing photos before sending. Ideal for newsletters and client communication.
Save Storage Space
Compress large photo libraries to save disk space on your device or cloud storage.
Faster Uploads
Compressed images upload faster to CMS platforms, social media, and e-commerce sites.

Frequently Asked Questions
1. What quality setting should I use?
For most web use cases, 70–80% quality provides an excellent balance between file size and visual fidelity. For print or archival, use 90%+. For thumbnails or previews, 60% is often sufficient.
2. Does JPEG or WebP compress better?
WebP typically compresses 25-35% better than JPEG at equivalent visual quality. However, JPEG has near-universal compatibility while WebP has strong modern browser support.
3. Will transparent PNG backgrounds be preserved?
No. Both JPEG and WebP (in lossy mode) will fill transparency with a white background. To preserve transparency, use a lossless format like PNG.
