Before you use this tool
Questions and limits
Does my file leave this device?
No file content is sent by this tool. The active processing path runs in this browser and is covered by an automated egress test.
Does PigPDF change my source file?
No. The source stays unchanged and PigPDF creates a separate output file.
Which current limits apply?
One compatible encrypted PDF up to 100 MB. A correct password is required; the password is not uploaded or stored and the rewritten result requires review.
