Optional browser encryption
When encryption is enabled, your browser encrypts the text or file before upload. FilePaste stores ciphertext and does not receive the decryption key.
Secure temporary file sharing
Secure file sharing with optional browser encryption
FilePaste helps you share text or one file with a short-lived link. Turn on encrypted file sharing when you want the browser to encrypt content before upload and keep the decryption key in the link fragment.
Protection model
What FilePaste can protect
Time-limited links
Choose 1 hour, 1 day, 7 days, or 30 days. After that window, the link stops working and stored data is removed on the next expired access.
No accounts
There are no dashboards, folders, or user accounts. Create one link, send it to the right person, and keep the full URL private.
80 MB limit
Each share can contain one file or one text paste up to 80 MB. Larger transfers need a different tool.
Important limits
What FilePaste cannot protect
Encrypted sharing protects the stored content from being readable without the key, but it does not make a link private after you send it. Anyone who receives the full URL, including the part after #, can decrypt while the link is active.
The # fragment is not sent to FilePaste in normal HTTP requests, but it can still appear in places you control, such as clipboards, screenshots, browser extensions, chat previews, or forwarded messages. Treat the complete URL like the secret.
For sensitive handoffs, choose encryption, use the shortest useful access window, and send the full link through a channel you trust.
If the fragment is missing, FilePaste cannot reconstruct it. The server only has encrypted data, so there is no recovery path for encrypted shares without the full link.
Link handling
Share the full URL carefully
Copy everything
Encrypted links need both parts: the short FilePaste URL and the # fragment after it. The copy button includes both.
Choose the shortest useful window
Short access windows reduce how long a link can be used if it is forwarded or pasted into the wrong place.
Share with intended recipients
FilePaste does not add passwords or recipient checks. The link itself grants access until the chosen window ends.
FAQ
Secure sharing questions
Can FilePaste read encrypted files?
Not when browser encryption is enabled and the key stays in the link fragment. FilePaste stores encrypted data and serves it back to the browser for local decryption.
What happens if I lose the key or copy only part of the link?
The encrypted share cannot be decrypted. Copy and save the full link, including the part after #.
Who can open a share link?
Anyone with the active link can open it. For encrypted shares, they need the full link with the key fragment.
When does a link stop working?
You choose the access window before upload: 1 hour, 1 day, 7 days, or 30 days. After that, FilePaste returns an expired response.
What is the upload size limit?
Text and file shares are limited to 80 MB each, including encrypted uploads.
