Lock your PDF with a password and keep it out of cloud storage entirely. Crafex protects documents with zero-storage, transient processing — nothing is saved after download.
or
Single file supported
Files are processed transiently and never written to disk, stored, or indexed on our servers.
The moment your result is ready, the in-memory payload is released. Nothing survives the job.
No account, no tracking of your documents, and never a copy left behind for anyone to access.
Nowhere. Protection runs through a zero-storage pipeline: the document exists only transiently in memory during processing and every reference is released the moment your encrypted PDF is ready to download.
Yes. Crafex applies industry-standard AES-256 encryption to your document. Combined with zero cloud storage, an attacker would need both the password and access to a machine that never held a stored copy of your file.
Absolutely. The protect tool works anonymously with no sign-up, so you can secure NDAs, salary documents and legal files without creating an account or leaving a footprint.
No copy is kept. After you download the encrypted PDF, the in-memory payload is discarded immediately. Crafex retains no document bytes at any point in the pipeline.
Add password protection and encryption to your PDF documents for enhanced security.
