The source of corruption

PDFs usually break due to interrupted downloads, failing hard drives, or bad email encoding.

Attempting a repair

Sometimes, the file structure is just slightly malformed. You can often repair a PDF by forcing a new software engine to rebuild it. Try running the broken file through a tool like Compress PDF or PDF to Word. Our internal rendering engine will attempt to ignore the broken syntax and generate a fresh, clean file.
