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, WebP, or AVIF compress better?
AVIF offers the best compression (up to 50% smaller than JPEG), followed by WebP (25-35% smaller). While JPEG has universal compatibility, WebP and AVIF are supported by most modern browsers and are recommended for web performance.
3. Will transparent PNG backgrounds be preserved?
No. JPEG, WebP, and AVIF (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.
