How to zip files
Choose the files
Choose files, a whole folder, or drop them in the box. You can add more than once and remove what you don’t want.
Set the options
Compression level, the file name, and a password if you want to protect it.
Download the ZIP
Press “Zip and download”; you see its size before and after.
How much smaller will it get?
It depends on the type of file:
| File type | Usual saving |
|---|---|
| Text, CSV and code | Large: 60% to 90% |
| Older Word and Excel files (doc, xls) and BMP images | Good: 30% to 80% |
| Small to medium, depending on its content | |
| JPG and PNG images, video, docx and xlsx files | Very little or none: they are already compressed |
| ZIP and RAR files | None |
Passwords
AES-256 is the strongest. Opens with 7-Zip or WinRAR on Windows, apps like Keka or The Unarchiver on Mac, and most phone apps. Windows Explorer itself can’t open it.
ZipCrypto is for compatibility only. Opens in Windows and macOS without extra software, but its protection is weak and can be broken, so don’t rely on it for sensitive files.
We can’t recover your password. The password stays in your browser and is never sent anywhere. If you forget it, the files can’t be recovered.
FAQ
How do I zip a whole folder?
Press “Or choose a folder” and pick it, or drag it into the box from your computer. The folders inside keep their structure in the ZIP.
Will non-English file names show correctly when unzipped?
Yes. File names are written in UTF-8 with the flag that tells programs so, and show correctly on Windows, Mac and phones.
How do I make a password-protected ZIP?
Type the password before zipping and pick the protection: strong AES-256, or ZipCrypto if the person opening it only has Windows with no extra software.
Why didn’t my photos and videos get much smaller?
They are already compressed in their own format. To shrink photos use Image Compressor before zipping them.
Are my files uploaded to a server?
No. The ZIP is made inside your browser and your files never leave your device. The limit is your device’s memory, so zip huge sets (several GB) with a desktop program.
