- Encrypted 7zDeclined with a reason
- Large filesIn-memory; warned first
The .7z extension usually means a detour to download 7-Zip, except on machines where installing anything is forbidden or unwanted. This page is the alternative: the archive is read in memory, you choose a destination folder, and the contents unpack there with their hierarchy intact. Encrypted 7z archives are the stated exception, refused with a reason, since their encryption is beyond the bundled reader. For the everyday unprotected 7z, no software, no waiting, no upload.
Questions
Why does 7z need special software normally?
The format never entered operating systems' built-in extractors the way ZIP did; 7-Zip and friends fill that gap, and this page fills it without the install.
What happens on a browser without a folder picker?
Files download one by one instead of landing in a folder; the contents are the same.
Memory limits?
Contents unpack in memory; very large archives trigger a warning before starting.
