Save Storage Space
Compress large photo libraries to save disk space on your device or cloud storage.

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 high-quality prints or original archives, use 90%+. For small thumbnails or previews, 60% or lower is often sufficient.
2. Does JPEG or WebP compress better?
WebP typically compresses 25-35% better than JPEG at an equivalent visual quality level. While JPEG has universal compatibility, WebP is now supported by all major modern browsers and is recommended for web performance.
3. Will transparent PNG backgrounds be preserved?
No. Both JPEG and WebP (in lossy mode used here) will fill transparent areas with a solid white background. To keep transparency, you should use a lossless format or our dedicated PNG tools.
4. Is my data secure during compression?
Yes. All compression happens locally in your browser using the Canvas API. Your images never leave your computer and are never uploaded to our servers, ensuring total privacy.
