Frequently asked questions
Does it support password-protected 7Z?
No: encrypted 7Z archives cannot be decrypted in the browser and you will see a clear notice. All other 7Z archives work normally.
Is there a size limit?
Up to 250 MB per archive: plenty for documents; for huge backups use a desktop tool.
Can I turn it into a ZIP?
Yes, with 7Z to ZIP in one step.
