Quick Answer
How do I corrupt a PDF safely?
Use Hexwilt to mutate PDFs locally in three steps: load, choose a mode, download the corrupted copy with a report.
Load PDF locally
Pick Byte Flip or Header Tamper
Download file + report
Open Hexwilt in your browser and drop in the PDF. The file never uploads to a server, so regulated content stays private.
Choose a corruption mode. Byte Flip introduces visual glitches for UX testing, while Header Tamper triggers hard failures for compliance drills.
Download the corrupted PDF along with the corruption report. The report captures seed, mode, and checksum deltas so you can replay or document the run.
