PDF · up to 100 MB per file

Change the fields in Document Properties. Two real uses: clearing before sending a file out — metadata often keeps the original author, company name, internal paths and notes like "draft, do not share"; and filling them in when archiving — a pile of scans with empty titles is hard to search or manage. Two deliberate rules: empty fields are never touched (quietly clearing what you did not fill in is the most damaging default such a tool can have: you wanted to add a title and the author and keywords someone else spent time on are gone), and clearing is its own switch rather than a side effect of leaving fields blank — the latter cannot express "clear the producing software, keep the title".

Features

  • Edit title, author, subject and keywords (keywords split on commas)
  • One switch clears everything, including creator and producer
  • Empty fields are left alone — only what you fill in is changed
  • The creation date is preserved (it is the document's history); only the modification date updates
  • The producing software is never replaced with this tool's name (many tools do that)
  • The result lists which fields were actually changed
  • Nothing is uploaded and no server is involved

How to use

  1. Drop a PDF in
  2. Fill in the fields to change (empty ones stay as they are)
  3. Tick Clear all metadata if that is the goal
  4. Download the result and check it with the PDF Info tool

FAQ

What happens when metadata is cleared?
Title, author, subject, keywords, creator and producer all become empty. The pages are untouched — count, sizes and text are all still there. The creation date is kept (that is the document's history, not a privacy leak) and the modification date updates to now, because the file really was modified. Running PDF Info afterwards shows the result, which is the most direct way to verify this kind of edit.
Why clear the producing software too?
Because it is a fingerprint: `Producer` and `Creator` record which software and version produced the file (a specific layout app build, the name of an internal system, sometimes the server or library that generated it). None of it helps a reader, and it tells them something about your toolchain. If you do need to keep it — an archive that records provenance, say — leave the switch off.
Can I undo a change?
Not within the tool — the output is a new file. Your original is never modified (the tool only reads it), so process it again. Note also that the changed file is a separate file, so do not overwrite the original if you might want to step back; keep the original and each result.
Is the file uploaded?
No. A few fields inside the PDF are changed in browser memory (with pdf-lib), with no network requests, and it works offline.
