How to edit PDF metadata with OnyxPDF
- Drop your PDF into the tool — its current metadata is shown.
- Edit the title, author, subject and keywords fields.
- Click “Save Metadata”.
- Download the PDF with corrected metadata.
Why do it in your browser instead of uploading?
- Fix embarrassing defaults: “untitled” documents and scanner-software authors replaced with proper values.
- No upload — the metadata of an internal document is none of a server’s business.
- Free and instant; several big tools lock metadata editing in paid tiers.
- Page content is untouched — only the document info dictionary changes.
Good to know (honest limits)
- This edits the standard info fields (title, author, subject, keywords). Deep XMP metadata editing is not included.
- Metadata can reveal information — if you are scrubbing a file for release, check the viewer in PDF Info first to see what is stored.
Frequently asked questions
Why does metadata matter?
It is what people see: the title shows in browser tabs and reader windows, the author shows in document properties, and sloppy metadata looks unprofessional on reports and proposals.
Can I remove metadata entirely?
Clear the fields and save — the standard fields will be empty. For a full inspection of what a PDF carries, use the PDF Info viewer.
Does editing metadata change my pages?
No. Only the info fields change; every page is byte-identical in content.
Is the file uploaded?
No. Metadata is read and written locally in your browser.
