Free file hosting
Free file hosting with links that expire on their own
Upload a file, get a link to share, and let it delete itself after the time you choose. No account, no cost, and an optional password for private shares.
What you get
Biohost is a free, temporary file host. It is built for the everyday case: share a file with someone now, and have it disappear automatically afterwards — without signing up or leaving the file online forever.
No account needed
Upload and share instantly — there is nothing to sign up for.
Automatic expiry
Pick 1, 3, or 5 days. The file is deleted when the timer ends.
Password protection
Lock private files so only people with the password can open them.
Unguessable links
Share URLs use long random IDs, so files cannot be discovered by guessing.
Frequently asked questions
- Is Biohost really free?
- Yes. Uploading a file and sharing a temporary link is free, with no account required.
- Do I need to create an account?
- No. There is no sign-up for uploading or downloading — you just upload and share the link.
- How long are files kept?
- You choose 1, 3, or 5 days at upload. When that time is up, the file is permanently deleted and the link stops working.
- Can I protect a file with a password?
- Yes. Enable password protection at upload time and the recipient must enter the password to view or download.
