How to check a PDF’s info and metadata with OnyxPDF
- Drop your PDF into the tool.
- Read the report: pages, sizes, version, title, author, creator, producer and dates.
- Optionally jump to Edit Metadata to fix anything wrong.
Why do it in your browser instead of uploading?
- No upload — inspecting a sensitive file does not expose the file itself.
- Catches pre-share surprises: your name in the author field, a scanner’s producer string, the wrong page size.
- Instant — no processing queue, just a local read.
- Pairs with Edit Metadata: inspect here, fix there.
Good to know (honest limits)
- It reports the standard document-info fields and pdf.js metadata; deeply hidden custom XMP packets are summarised, not decoded field-by-field.
- Encrypted files must be unlocked before their internals can be read.
Frequently asked questions
What can this tell me about a PDF?
Page count and each page’s dimensions, PDF version, title, author, subject, keywords, creator and producer software, and creation/modification dates, where present.
Why check metadata before sharing?
PDFs quietly carry author names, software and timestamps. A ten-second check prevents leaking details you did not intend to publish.
Can I change what I see here?
Yes — the Edit Metadata tool rewrites title, author, subject and keywords.
Is the file uploaded for inspection?
No. The file is parsed in your browser; nothing leaves your device.
