Host a 7z file and share it as a link
Put a 7-Zip archive online at its own address — the format that compresses harder than ZIP when size really matters.

Any other file works too — up to 25.0 MB, or 100.0 MB for a whole site
Free to use. Your 7Z file is live at your-name.99helpers.site in about ten seconds.
What is a .7z file?
7z is the archive format of 7-Zip, using LZMA compression that typically produces files 20–40% smaller than the equivalent ZIP. It also supports AES-256 encryption of both contents and filenames, which ZIP's older encryption doesn't do well.
What people use 7Z files for
- Large software distributions and backups
- Archives where every megabyte counts
- Encrypted bundles where filenames should also be hidden
- Collections of many small files, which LZMA handles very efficiently
What opens a 7Z file
- 7-Zip on Windows, free and open source
- Keka and The Unarchiver on macOS
- p7zip on Linux
- Neither Windows nor macOS opens .7z without extra software
How to host a 7Z file
- 1
Drop your 7Z file in
Drag it onto the box at the top of this page, or click to choose it. Files up to 25 MB are supported, and nothing is uploaded until you publish.
- 2
Pick an address
Type a name and we'll tell you straight away whether it's free. That becomes the link: software-bundle.99helpers.site
- 3
Publish and share
Create a free account — that step exists so the file is yours to update, replace or delete — and the link is live within seconds.
The same three steps work for any file — see how file hosting works on 99helpers.com.
What happens when someone opens the link
The archive downloads. Unlike ZIP, neither Windows nor macOS unpacks 7z natively, so recipients need 7-Zip, Keka or similar — worth mentioning when you send the link.
Why host a 7Z file instead of emailing it?
7z is chosen when a file needs to be as small as possible, usually because it's large to begin with. A direct link downloads at full speed and doesn't expire, which matters more for big files than small ones.
Worth knowing before you publish
- Recipients need extra software, unlike ZIP — say so when you share, or use ZIP if convenience matters more than size.
- 7z's AES-256 encryption can hide filenames as well as contents, which ZIP can't do properly.
- Compression is slow at the highest settings; the difference between Normal and Ultra is often marginal.
7Z hosting questions
- Can Windows open a .7z file?
- Not on its own — Windows unpacks ZIP but not 7z. Recipients need 7-Zip, which is free, or another archiver. If they might not have one, ZIP is the safer choice.
- Is 7z better than ZIP?
- Smaller files, typically by 20–40%, and better encryption. ZIP wins on convenience, since every operating system opens it without extra software.
- Is a password-protected 7z secure?
- Its AES-256 encryption is sound, and it can encrypt filenames too. The link itself is public, so the password is what protects the contents — send it separately.
