常见问题
Can this compress any file type?
Yes. Any binary or text file, image, PDF, audio, or source code can be processed.
What is the difference between the 3 compression levels?
Minimal is ultra-fast with low CPU usage; Balanced offers the ideal size-to-speed ratio; Maximal performs deep dictionary search for the smallest byte size.
Are my files uploaded to a server?
No. All compression is executed in browser RAM using the native Web Streams API. No data leaves your machine.
