Overview

Control the hidden details inside your PDF

Edit PDF Metadata lets you view, change, or remove a PDF's hidden properties — Title, Author, Subject, and Keywords — in your browser. Edit one file or a whole batch, scrub the fields for privacy, and download. Nothing is uploaded, so your documents stay on your device.

Drop in a PDF and a card appears with a thumbnail preview and a form holding the current values. Type a proper Title so the document reads as "Q3 Financial Report" rather than "Microsoft Word - Document1.docx", add an Author, write a Subject, and list comma-separated Keywords to make the file easier to find in desktop search or a document system. To scrub metadata for anonymity — useful before publishing or sending sensitive files — just clear the fields.

Working with many files? Load them all, fill in the first one, and click Apply First File's Data to All to copy the Title, Author, Subject, and Keywords across the whole queue — a real timesaver for archiving or tagging a project's documents. Save each file individually, or grab everything as a ZIP.

Everything runs locally, which matters more here than almost anywhere: metadata is privacy, and your files are never uploaded to a server. Editing the properties doesn't touch the page content — text, images, and layout are untouched, there's no quality loss, no watermark, and no signup.

A quick honest note: this edits the standard Document Information fields (Title, Author, Subject, Keywords). If you need to verify nothing else lingers, Compare PDF can check versions before you distribute.

When editing metadata helps

Guide

How to edit PDF metadata

Step 1: Upload your PDF(s)

Drag in one or several files, or click Select PDF Files. Each gets a card with a preview and a metadata form.

Step 2: Edit the fields

Update the Title, Author, Subject, and Keywords — or clear them to scrub the metadata.

Step 3: Batch if needed

With multiple files, fill the first one and click Apply First File's Data to All to copy the values across the queue.

Step 4: Download

Save each file with Save & Download PDF, or click Download All (ZIP Archive) for the whole set.

Realistic example. You scanned 20 invoices for one client. Set the first file's Author to your company and Subject to "2026 Invoices", click Apply First File's Data to All, then Download All (ZIP) — every file is consistently tagged in seconds.

Advanced tip. For anonymity before publishing, use Clear All Fields to blank the Title, Author, Subject, and Keywords so the file carries no identifying properties.

Common mistake to avoid. A clean filename isn't the same as clean metadata — rename the file and set the Title field, since viewers often show the Title, not the filename.

Recommendation. Want to lock the file after tagging? Protect PDF. Need to remove visible content too? Remove Images.

Frequently Asked Questions

How do I edit a PDF's metadata?

Upload the PDF and a form shows its current Title, Author, Subject, and Keywords. Edit any field, then click Save & Download PDF. To remove the metadata instead, clear the fields. You can load several files and batch-apply the same values. Everything runs in your browser with no upload.

Which metadata fields can I change?

The standard document properties: Title, Author, Subject, and Keywords. The Title is what viewers show in the tab, the Author identifies the creator or organisation, the Subject describes the document, and Keywords (comma-separated) help search and document systems find it.

How do I remove or scrub metadata for privacy?

Clear the text from the fields and download — that strips the Title, Author, Subject, and Keywords so the file carries no identifying properties. This is useful before publishing anonymously or sending sensitive documents, since metadata can otherwise reveal who created a file and with what software.

What does the Title field actually affect?

The Title is what most PDF viewers and browsers display in the tab or window, often instead of the filename. It's also used when libraries and document systems index the file. Setting a clear Title (like "2026 Annual Report") makes the document look professional and easier to identify than a default like "Document1".

Can I edit metadata for several PDFs at once?

Yes. Load multiple files, fill in the metadata for the first one, then click Apply First File's Data to All to copy the Title, Author, Subject, and Keywords across the whole queue. Download them individually or as a single ZIP — ideal for tagging a project's documents consistently.

Does editing metadata change the page content or quality?

No. Metadata lives in a separate part of the file from the pages, so editing it leaves your text, images, and layout completely untouched. There's no quality loss — you're only changing the document's descriptive properties, not its visible content.

Are my files uploaded — is it safe?

No. The metadata is read and rewritten entirely in your browser, so the PDF never leaves your device or reaches a server. That's especially important here, because metadata is itself a privacy matter. Closing the tab clears the file from memory.

Can I edit PDF metadata on my phone's browser?

Yes. The tool works in any modern browser on iPhone or Android — no app needed. Upload, edit the fields, and download. Batch editing several files is easier on a larger screen, so a laptop is more comfortable for big jobs.

Is it free, with no watermark or signup?

Yes. Editing metadata is free, nothing is watermarked, and there's no account to create. Change or clear the fields and download — no paywall before the download.

Does it edit XMP or other hidden metadata too?

The tool edits the standard Document Information fields — Title, Author, Subject, and Keywords — which cover what most viewers and search systems read. For highly sensitive distribution, treat editing these as the main step and verify the result; deeply embedded XMP from specialised software may need a dedicated metadata utility.

Does it change my original PDF?

No. The tool creates a new file with the updated metadata for you to download; your original stays exactly as it was on your device. Keep the original if you might need the old properties back.

Why does PDF metadata matter?

Two reasons. For professionalism and findability, a clean Title and good Keywords make a document look polished and surface in search. For privacy, metadata can expose the author, organisation, and software — so scrubbing it before sharing protects you, which is exactly why doing it locally (never uploaded) matters.
