Frequently Asked Questions

Are my images uploaded to your servers?

No! Conversion takes place 100% locally inside your web browser using HTML5 Canvas API. Your images never leave your computer.

WebP provides superior lossless and lossy compression, resulting in 25-35% smaller file sizes compared to PNG and JPEG while preserving identical visual quality.
