LibreOffice Writer

Q: How should I read the LibreOffice Writer statistics?

The figures describe the 46 files in the HTPBE corpus that list LibreOffice Writer as Creator or Producer. The modification rate is the share of those files that carry modification markers. It is a base rate for this particular set of files, not a property of LibreOffice Writer and not a prediction for any single document.

Q: How do I check a PDF that lists LibreOffice Writer?

Upload it to HTPBE for a modification check, or open it in the free PDF Metadata Viewer to see the Creator, Producer and dates stored in the file. The same check is available through the HTPBE API.

LibreOffice Writer appears on both unmodified and modified documents in our corpus. The name alone is never the verdict; each file is judged on its own structure.

How LibreOffice Writer shows up in HTPBE? corpus

LibreOffice Writer is the word-processing component of LibreOffice.

Writer appears on letters, reports and other word-processed documents. The name is a starting point; the verdict depends on what the rest of the file shows.

Reading guide

How to read this page

Every PDF stores two software labels: the Creator, which names the application that first produced the document, and the Producer, which names the software that last wrote the file out. This page counts the files HTPBE? has analysed where LibreOffice Writer fills one of those labels, and shows how often those files carry modification markers, which PDF versions they use and which other tools sit next to them.

A tool name tells you where a file passed through, not whether anyone changed its content. A Creator and Producer that agree usually point to a single pass; a Producer that differs from the Creator means the file was written out again by another program, which has many ordinary explanations such as compression, merging or a print-to-PDF step.

Caveats

The figures cover 46 files. Larger than a handful, but still a sample of what was submitted, not of all PDFs in the world.
The statistics describe files HTPBE? analysed. They are not a judgement of the quality or trustworthiness of LibreOffice Writer.
Submitted files lean towards documents that someone wanted checked, so rates here can sit higher than in everyday document flows.
Metadata can be rewritten by anyone, so a producer name on its own is never treated as proof either way.

How LibreOffice Writer shows up in metadata

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.

FAQ

LibreOffice Writer in PDF metadata: common questions

What is LibreOffice Writer?

LibreOffice Writer is the word-processing component of LibreOffice.

Why does LibreOffice Writer appear in the metadata of a PDF?

A PDF can record the software that created it (Creator) and the software that last wrote the file out (Producer). When LibreOffice Writer generated the file, or re-saved it, it can leave its name in one of those fields. The field is filled in by software, not checked by anyone, so it is a hint about the file’s history rather than a guarantee.

Does LibreOffice Writer in the metadata mean the PDF was edited?

No. A producer name alone proves nothing about whether a document was changed. Many LibreOffice Writer files are original output, and a file that was edited can name any tool at all. What matters is the whole picture: how the file is built, how its dates and structure line up, and whether the Creator and Producer fit together.

How should I read the LibreOffice Writer statistics?

The figures describe the 46 files in the HTPBE? corpus that list LibreOffice Writer as Creator or Producer. The modification rate is the share of those files that carry modification markers. It is a base rate for this particular set of files, not a property of LibreOffice Writer and not a prediction for any single document.

Can I compare LibreOffice Writer with other tools using these numbers?

Only loosely. The corpus consists of PDFs people chose to submit for checking, which skews towards documents someone had a reason to doubt. A tool popular for legitimate bulk output can still show a high rate here, and a rarely seen tool can show an extreme rate from a handful of files. These pages are not a quality ranking of the tools themselves.

How do I check a PDF that lists LibreOffice Writer?

Upload it to HTPBE? for a modification check, or open it in the free PDF Metadata Viewer to see the Creator, Producer and dates stored in the file. The same check is available through the HTPBE? API.
