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.
No. Crafex merges your PDFs with zero cloud storage. Files are processed without persistence — the combined document is delivered to you and every trace of the input is discarded immediately after processing.
Never. Crafex runs a zero-storage pipeline: uploaded data lives only transiently in memory during processing and is released the instant the merged file is generated. Nothing is written to disk and nothing is saved to a database.
No account is required to merge PDFs on Crafex. You can merge, split, compress and protect documents anonymously with the same zero-storage guarantee.
Most online PDF mergers upload and store your file on the vendor's cloud storage. Crafex is architected for zero cloud storage — in-memory, transient processing with immediate payload release, so there is nothing left on our servers to leak.
Combine multiple PDF files into one single document online for free. Fast, 100% private, client-side processing with zero file size limits.
