Questions & answers
Good to know
Common questions about size, privacy, and cost.
Is my zip uploaded anywhere?
No. Everything runs in your browser, your files and password never leave your device, and nothing is sent to a server. (Only the zip engine code is downloaded.)
How strong is the encryption?
AES-256, real, strong encryption. To open a protected zip, the recipient needs a tool that supports AES zips: 7-Zip, Keka, The Unarchiver, or Windows 11. The built-in macOS Archive Utility cannot open AES zips.
Can you remove a password I forgot?
No. Removing a password requires the password you already know, this is real encryption, not a cracker. If you have lost the password, it cannot be recovered.
Does it cost anything?
No, it is completely free, no signup.
