Edit PDF Metadata
Processing entirely on your device — large files may take a moment.
A PDF's metadata is what the reader tab, file manager and search index actually display — a titled, authored document looks credible in every one of them. Fill what you want; empty fields keep their current value.
Keywords accept a comma-separated list and become the indexed keyword set. The modification date updates automatically so the change is traceable.

About the PDF format
PDF (Adobe, 1993; ISO 32000 since 2008) exists for one promise: the document looks identical everywhere, forever. Fonts get embedded, layout is fixed to the point, and a contract printed from a 2003 file renders the same as one created this morning. That fixed-layout guarantee made it the standard for invoices, manuals, forms, e-books and anything with legal or financial weight.
The same design is what makes PDFs stubborn. They are meant to be presented, not edited — text lives in positioning operators rather than paragraphs, so extraction and re-flow are approximations. Scanned PDFs are worse: pure images with no text layer at all until OCR enters the picture. Still, no other format comes close for final-form document delivery.
+Strengths
- ✓Pixel-identical rendering on every device and printer
- ✓Fonts, images and color profiles travel inside the file
- ✓Mature ecosystem: forms, signatures, annotations, encryption
!Limitations
- −Hard to edit by design — even small changes need tooling
- −Text extraction is an approximation, not a conversion
- −Scanned PDFs are images without OCR
Frequently asked questions
Do I have to fill every field?
No — only the fields you fill in are written; everything you leave empty keeps its existing value.
Can I clear a field instead?
Yes — run the metadata remover first, then set exactly the fields you want with this tool.
Where does the title show up?
In the reader's tab and title bar, in file-manager listings, and it is the first thing search engines read when indexing the PDF.
