Why compress locally?

Compressing images locally in your browser ensures maximum privacy and speed. Your photos never leave your device, eliminating the risk of data breaches. Because no data is uploaded to a remote server, the compression process is instant and bandwidth-efficient.

  • JPG/JPEG: Best for photographs and realistic images.
  • PNG: Ideal for screenshots and images with transparency.
  • WebP: Modern format providing superior compression for web use.

Frequently Asked Questions

Is there a file limit?▼

No. Unlike other tools (e.g., TinyPNG), YuliusBox runs locally on your device, so there are no arbitrary limits on file size or count.

Is it secure?▼

Yes, 100% secure. Your images are processed using browser technologies (Canvas/WASM) and never uploaded to any server.
