Get heavy PDFs under email attachment limits without cloud storage. Crafex compresses transiently — your file is never persisted, so it cannot be mined, indexed or leaked.
100% Safe & Private: Files are processed directly in your browser and never uploaded to any server.

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.
No. Compression is transient and zero-storage: the file exists in memory only for the duration of the job and is released immediately after the smaller PDF is produced.
High compression re-encodes embedded images and strips optional metadata, typically taking large documents comfortably under common email limits — without ever uploading your file to cloud storage.
Yes. Since Crafex stores nothing, sending confidential contracts by email after compressing them here never leaves a copy of the document on any third-party server.
