# Jetdrop

> Jetdrop (https://jetdrop.net) is a free, zero-knowledge, end-to-end encrypted
> file-transfer web app by AnySoft. Send files up to 100 GB with no account:
> files are chunked, deduplicated, compressed, and AES-256-GCM encrypted in the
> browser before upload — the decryption key travels in the link's #fragment
> and never reaches the server, so Jetdrop cannot read users' files.

## Key facts

- Price: free forever, no accounts, no paid tiers (funded by AnySoft, whose
  business products are advertised on the page)
- Max transfer size: 100 GB (single or multiple files)
- Encryption: client-side AES-256-GCM; zero-knowledge (key in URL fragment)
- Optional PIN/passcode protection: the key is additionally wrapped with a
  PBKDF2-derived key on the sender's device; receivers must enter the code
- Link expiry: 1 hour, 12 hours, or 7 days — encrypted data is deleted after
- Live streaming transfers: a receiver who opens the link mid-upload streams
  blocks as they land and finishes moments after the sender does
- Engine: content-defined chunking with block-level deduplication and
  compression; uploads go browser-direct to object storage
- Pause/resume/cancel supported; cancelling deletes already-uploaded data

## Notes for crawlers

- The app is a JavaScript SPA; the homepage ships static descriptive HTML and
  schema.org JSON-LD (WebApplication, FAQPage) for non-JS clients
- Transfer links (paths like /s…) are private, ephemeral pages and are marked
  noindex — please do not surface them
