Edit PDF Metadata in Your Browser
No account. No upload. Just the tool.
PDFs carry small metadata fields that most people forget exist — a title, an author name, the program that created the file, a subject line, keywords. They’re set automatically when you export a PDF and rarely updated after. Signegy lets you edit those fields right in your browser. No upload, no signup.
What’s Editable
- Title — what shows in the browser tab when the PDF is opened, and in document properties dialogs.
- Author — typically the user account that created the source document. Set this if the original is wrong or you’d rather not share it.
- Subject — a one-line description of the document’s purpose.
- Keywords — comma-separated terms used by some search and indexing tools.
- Creator — the application that created the source document (e.g., “Microsoft Word”). Set or clear it.
- Producer — the library that produced the actual PDF bytes (e.g., “macOS PDF” or “Acrobat Distiller”).
Common Reasons to Edit Metadata
Send a polished file. A signed contract whose title is still “Document1.pdf” reads as careless. Set the title to something like “Sales Contract — ACME / 2026-04-30” before you send.
Strip identifying details. Word and other authoring tools often stamp the active user account into the Author field. If you don’t want the recipient to see that, clear it.
Make a file findable. Keywords are an underrated way to surface a document later in a search index — your own laptop’s Spotlight, your team’s document store, even Google Workspace search.
Cleanup after a re-export. Sometimes you regenerate a PDF and the metadata reverts to defaults. Quickly reset the title and author back to what they should be without re-exporting again.
What This Tool Won’t Do
- Doesn’t strip every trace of metadata. PDFs have internal trailer IDs, timestamps, and structural information that aren’t shown in document properties. If you need a forensic-level scrub, regenerate the PDF (open in a viewer, print to PDF).
- Doesn’t change content. Only the metadata fields are edited. Page contents are untouched.
- Doesn’t work on encrypted PDFs. You’d need to unlock the file first.
Pair With Other Tools
- After editing metadata, compress the PDF before email if it’s large.
- Sign the PDF — Signegy’s signing flow doesn’t overwrite the metadata you set.
- Merge PDFs inherits metadata from the first file in the order. Set yours first, then merge.

Frequently Asked Questions
What is PDF metadata?
Metadata is the small bundle of information attached to a PDF that isn't part of the visible content: title, author, subject, keywords, the program that created the file, and a few internal IDs. It shows up in document properties dialogs, in search results, and in any tool that catalogs PDFs.
Why would I want to change it?
Privacy (the original author or creator program may give away information you don't want shared), organization (a clear title and keywords make a PDF easier to find later), and professionalism (sending a contract whose title is still 'Untitled' or 'Document1.pdf' looks unfinished).
Does this remove all metadata?
Setting a field to an empty string clears it from the document properties dialog. PDF format also has internal trailer IDs and timestamps that aren't user-facing — those persist. For a stricter privacy pass, regenerate the PDF entirely (e.g., print to PDF from a viewer).
Can I edit metadata on encrypted PDFs?
Not from this tool. Password-protected PDFs need to be unlocked first.
Is anything uploaded?
No. The PDF is read, edited, and saved entirely in your browser using pdf-lib. Nothing leaves your device.
