Frequently Asked Questions

Does the image ever leave my device?
No. Compression is performed using the HTML5 Canvas API directly in your browser. Your image never leaves your device.
Which format gives the best compression?
WebP generally achieves the best file size reduction while maintaining quality, often 25-35% smaller than equivalent JPG files.
Why does PNG not have a quality slider?
PNG is a lossless format — it cannot be 'lossy-compressed' like JPG or WebP. Converting a PNG to WebP or JPG will reduce file size significantly.
