Who is listed as the author of your PDF, and does the title say "final2"? The PDF Metadata Editor lets you fix those labels. You change six fields and download a new copy.
It suits freelancers, students, and office staff who share files outside their team. The page content is not changed, only the document properties.

What the Editor Does
After you load a file, the tool shows its name, size, and page count. Six fields become editable.
- Title, Author, Subject, Keywords, Creator, Producer: text boxes filled with the current values.
- Clear All Six Fields: empties all six boxes. It does not save anything yet.
- Restore Original: puts the loaded values back in the boxes.
- Download Updated PDF: saves your edits in a new file.
- Export Current Fields JSON: saves the six values in the boxes as a small JSON file.
- Status line: it starts as "Ready". Errors appear in a red message box.
- Metadata Comparison: a table with Field, Original Value, and New Value.
How to Use It, Step by Step
- Click the box that reads "Drag a PDF file here" and pick a PDF. Dropping a file onto it also works.
- Check the File, Size, and Pages lines. The status reads "PDF loaded. Edit the fields, then download."
- Type new text into any of the six boxes. The table updates as you type.
- Press Download Updated PDF. The status reads "Done. Your download has started." and your browser saves updated-document.pdf.
- Optional: press Export Current Fields JSON to save metadata.json.
How It Works
The tool loads your PDF with the pdf-lib library and reads its document information. It fills the boxes from that data. When you press the download button, it writes your six values back and saves the file.
Original values come straight from the file. Keywords are shown and saved exactly as you type them, so commas stay. An empty box removes that field from the file.
Choose PDF→Edit Six Fields→Check Comparison→Download Updated PDF
The file is processed in your browser. The code reads it locally and builds the new PDF in memory. It makes no network request that sends the file, so the PDF is not uploaded. Only the pdf-lib code library is fetched from the web.
Example: A Client Proposal
Sofia is a freelance designer. She exported a proposal from her layout app. The file says the Title is "proposal_v3_final2" and the Author is her laptop account name.
She loads the file and sees the Pages count and size. She types "Brand Refresh Proposal" as the Title and her full name as the Author. She adds "branding, proposal" as Keywords.
The table shows her old and new values side by side. She presses Download Updated PDF and sends updated-document.pdf to the client.
How to Read the Comparison Table
Each row is one field. The Original Value column shows what the file had when loaded. The New Value column shows what is in the box right now.
An empty value appears as "(empty)". New values show in green, so you can scan for changes before you download.
What the Editor Does Not Change
The Clear All Six Fields button clears only those six boxes. It does not touch other hidden information, such as dates, custom fields, or extra metadata blocks used by some apps. The tool says so itself, and it is not a full metadata remover.
Creation and modification dates have no boxes here and are not changed. The Original Value column shows what the file really held, including Producer and Creator.
To only look at a file's properties, use the PDF metadata viewer. For wider removal of properties, try the PDF metadata remover. The PDF file information viewer shows more file facts.
If you plan to combine files, run Merge PDF first and edit the properties last. Browse related tools in the PDF tools hub.
Limitations to Know
- Only six fields can be edited. Dates and custom fields cannot.
- Clear All Six Fields empties the boxes only. You must still press Download Updated PDF.
- Password protected files do not load. You see "This PDF could not be opened. It may be password protected or damaged." Unlock the file first.
- A non-PDF file shows "That does not look like a PDF".
- Export Current Fields JSON saves the current box values, not the original ones.
- The output name is always updated-document.pdf. Rename it as needed.
- The tool keeps no copy. Reload and upload again to start over.
FAQs About the PDF Metadata Editor
Does the PDF Metadata Editor upload my file?
No. The code processes the PDF in your browser and sends it nowhere. Only the pdf-lib library is loaded from the web.
Which fields can I change?
Title, Author, Subject, Keywords, Creator, and Producer. These are the six boxes on the page.
Does Clear All Six Fields remove everything?
No. It empties the six boxes. Other hidden data, such as dates, is not removed.
Will the page content change?
No. The tool edits document properties only. Text, images, and layout stay the same.
What happens to a box I leave empty?
The saved file drops that field. It does not store a blank value in its place.
Can I undo my edits?
Yes, before you download. Press Restore Original to refill the boxes with the loaded values.
