Upload a .7z archive and download its contents in seconds. Encrypted archives supported, up to 2 GB.
The .7z format compresses better than ZIP, but almost nothing opens it natively — not Finder, not Explorer, not your phone. Instead of installing 7-Zip, upload the archive here: it's extracted server-side (encrypted 7Z included), you pick the files you want, and the upload self-destructs an hour later.
7-Zip's own format squeezes files smaller than ZIP, so it's the default choice for large software downloads, game mods, driver bundles and anything shared where bandwidth matters. That's also why it lands on machines that have no idea what to do with it: Windows can't open .7z without 7-Zip installed, and macOS can't open it at all.
On text, source code and uncompressed data, LZMA2 — the algorithm behind .7z — routinely lands 30–50% below the same content zipped, because it looks much further back for repetition than ZIP's Deflate does. On material that is already compressed (JPEG, MP4, MP3) the gain collapses to almost nothing: those bytes have no redundancy left to find, whatever format you wrap them in.
That trade is why .7z shows up around big software and rarely around holiday photos.
7Z encryption is AES-256, and it comes in two flavours. The common one encrypts file contents: you can see the file names, but not open anything without the password. The stricter one also encrypts the header, so the archive looks empty until the correct password is supplied. Both work here — enter the password when prompted.
As with any format, a password you don't have cannot be recovered, and tools claiming otherwise are best avoided.
