Are my images uploaded to your servers for compression?

No. All image compression occurs 100% locally inside your web browser using HTML5 Canvas technology. Your photos and graphics never leave your device, ensuring complete privacy.

How much can I reduce my image file size without losing quality?

Typically, you can achieve 60% to 85% file size reduction with virtually zero noticeable loss in visual quality by setting the quality slider to 75%–85% and converting large PNGs to modern WebP format.

Which format produces the smallest file size: JPG, PNG, or WebP?

WebP consistently produces 25% to 35% smaller file sizes than comparable JPEG or PNG files while preserving full color fidelity and transparent backgrounds.
