Does zipping files reduce their total size?
Compression varies by file type — text and documents shrink significantly, while already-compressed formats like JPG, MP3, or video files barely shrink at all, since they're already compact.
Is there a limit on how many files I can zip at once?
No fixed limit — add as many files as you need; larger batches simply take a little longer to process.
Are my files uploaded to a server during zipping or extraction?
No — the ZIP archive is created or extracted entirely in your browser, so your files never leave your device.
