Create your ZIP in three steps
- Select the files you want to package together.
- Choose a compression level. Enter a password if you want an encrypted ZIP.
- Create the ZIP and download it. Your original files stay unchanged.
One archive, original file quality
ZIP packages multiple files with lossless compression. Extracting the ZIP restores the original file bytes. Text can compress well; photographs, videos and other compressed formats often become only slightly smaller.
Choosing a password
Use a strong password and send it to the recipient through a separate channel. ZIP encryption protects file contents, but filenames may remain readable. Keep the password: this tool cannot recover it for you.
Local processing, practical limits
Selected files and archive passwords stay on your device. Browser memory, archive size and compression method affect what can be processed. The tool shows its current limits and reports unsupported or unsafe archives. Use a desktop archiver for large backups, multipart sets or filesystem metadata that must be restored exactly.
