Multiple files allowed — same metadata applied to each
When to use this tool
Two common reasons. First, cleaning before sharing: PDFs generated by a CMS, report builder, or "Save as PDF" command often carry the original filename, the user account name, or the source application as metadata — sometimes information you don't want external readers to see. Second, setting useful titles: the embedded title is what shows up in browser tabs and document libraries when someone opens the file.
Step by step
- Drop the PDFs. The same metadata change is applied to every file in the batch — perfect for setting a consistent author across a folder.
- Fill in the fields you want to set. Leave fields blank to keep the existing value. Only fields you fill are written.
- Or tick "Strip all metadata" to clear title, author, subject, keywords, producer, and creator in one shot. With this on, the text fields above are ignored.
- Click "Apply & download". Confirm via Metadata inspector if you want to double-check.
Common use cases
- Clean before email. "Microsoft Word - confidential-draft-v3.docx" as the title is awkward; replace it with the public-facing name.
- Author hygiene. A scanned PDF carries the username of whoever ran the scanner; strip it before sharing externally.
- Batch consistency. Stamp every PDF in a folder with the same author / project name.
- Search-friendly metadata. Add keywords (comma-separated) so internal document search picks the file up properly.
- Pre-publishing strip. Strip everything before posting publicly to avoid leaking incidental info.
Common mistakes
- Forgetting metadata isn't the same as content. This tool only edits the Info dictionary. Personally-identifying text inside the body of the PDF (footer with your name, signature) is unaffected.
- Expecting strip to remove everything. The strip option clears the simpler Info-dictionary fields. PDFs may also carry XMP metadata (XML-based) that this tool doesn't currently touch. For full sanitisation use a desktop tool like
exiftool -all=. - Strip + fill at once. If you tick strip, the text fields are ignored. To set fresh metadata after stripping, run two passes (strip first, then set).
FAQ
Can I see what's currently in a PDF before editing?
Yes — drop the file in Metadata inspector first.
Does this remove form data or embedded files?
No — only the Info-dictionary string fields. Form fields, embedded files, and XMP metadata are untouched.
What's "producer" vs. "creator"?
"Creator" is typically the application the user used (e.g. Microsoft Word). "Producer" is the library that wrote the PDF (e.g. Adobe PDF Library, pdf-lib). Both are often automatically populated.
Are dates editable?
Not yet — only string fields are exposed. The CreationDate and ModDate are written by the underlying library on save and may be updated as a side-effect of any modification.
