iText reads as a downstream re-saver — it surfaces disproportionately on documents whose original Creator was a different, often institutional, application.
Back to all statisticsForensic verdictBased on 1,717 appearances across the HTPBE? corpus.
Corpus profile
iText is a Java/.NET PDF library used both for legitimate server-side document generation (custom invoicing, archival workflows) and for programmatic post-processing such as merging, stamping, and field-flattening.
iText appears in HTPBE? across both legitimate first-generation output and flagged documents where it shows up post-original creation. Signal: when iText is the latest Producer on a document whose Creator was an institutional source like Adobe PDF Library or Microsoft Word, that producer/creator mismatch is one of the markers we surface.
Role in the workflow
Every PDF carries a Creator (the application that produced the original document) and a Producer (the engine that wrote the PDF). The same tool can appear in either slot, with very different modification profiles.
Name fingerprints
Different version strings and spellings observed for iText in the wild. All are merged into the same canonical profile.
Why variants matter
The same tool publishes itself under 57 different metadata strings — version bumps, locale tags, build IDs. We canonicalize them so the corpus reflects one identity, not noise.
Distributions
The PDF versions iText writes when acting as Producer, and the other tools that appear in the same documents.
Most output is PDF 1.4 (40% of files where iText is the Producer).
JasperReports sits upstream in 44% of cases — read this row as “what kinds of documents end up routed through iText.”
Related profiles
Other tools that frequently share metadata with iText in the same documents. Each card links to its own forensic profile.
Long tail
Smaller cuts of the iText corpus — useful context, but treat each row as a single data point rather than a strong signal.
