Upload files of any size to your encrypted personal vault. Files are encrypted in your browser before upload — PQCServer stores only ciphertext it cannot read. Share with a shortlink or directly by username. Free. No limits.
The vault uses the same ML-KEM encryption as messaging — your files are encrypted before they ever leave your browser.
Files are split into 3MB chunks before upload. Each chunk is uploaded separately, bypassing any per-request size limits from CDN or proxy layers. The server reassembles the chunks server-side.
View all your vault files in a grid with icons, filename, size, upload date and access stats. Search by name, filter by tag, sort by date or size.
Every vault file gets a shortlink automatically. Generate new shortlinks anytime. Share directly with a registered username — they can download and decrypt with their own key.
Organize files with up to 10 tags and an optional note per file. Filter the dashboard by tag to quickly find what you need.
Vault files have no TTL — they remain until you explicitly delete them. Unlike messages (which expire), vault files are your permanent encrypted archive.
Deleting a vault file removes the GridFS chunks, all associated shortlinks, and the vault entry — completely and immediately. No lingering data.
Dashboard shows total files, total storage used, and per-file access count. Know exactly what's in your vault and how much space it uses.
Register, generate your keys, and upload your first file in under 2 minutes. Free forever.
