  • Checking email size handling
  • Checking in-browser PDF previews
  • Verifying text extraction and page counts

Testing notes for PDF

  • Page count and file size are unrelated: one scanned page can be larger than a 300-page text document.
  • A file cut off before its final "%%EOF" marker usually cannot be opened, which makes PDF a good format for detecting truncated transfers.
