Frequently asked questions

How much can the file size shrink?+

The reduction depends on the file's content; files with large images shrink more than purely text-based files.

Does compression affect text quality?+

No, text stays sharp and clear; compression mainly targets images and redundant data inside the file.

Is my file uploaded to any server while compressing?+

No, processing happens entirely in your browser through a compression engine that runs locally on your device.
