Help & Frequently asked questions
Each file is limited to 100 MB. Larger files should be split before uploading.
Files are kept for 30 days after their last download. A nightly cron job removes expired files to free storage. Files that have never been downloaded are removed 30 days after upload.
Files are encrypted server-side using AES. A fresh random key is generated for every upload and returned to the uploader as part of the view URL.
The server does not store decryption keys in the database. For convenience, the web uploader stores the key locally in your browser's localStorage (under keys) so you can easily view files you uploaded from this browser. This data never leaves your device — to remove saved keys, clear the site data or run localStorage.removeItem('keys') in your browser console. Keep keys safe; if you lose them and don't have a local copy, the file cannot be decrypted.
The upload response includes a delete URL that contains a delete token. Calling that URL (GET) removes the file and its database entry immediately.
Yes — use the ShareX configuration for direct automated uploads or integrate with your own scripts by POSTing to /upload.
Images, audio, video, and PDFs can be opened inline in the browser (Content-Disposition set to inline).
The server checks the SHA-256 checksum and rejects uploads when an identical file was uploaded recently (within ~30 minutes) to prevent duplicate storage.
