Free online PDF metadata editor that loads the Title, Author, Subject, Keywords, Creator, Producer, Language and both dates of a PDF into a form, then saves a copy with the values set or cleared. The visible page stays as it is.
Document format work by OnlinePCApps since 2013
The hidden properties of a PDF travel with it everywhere. A PDF metadata editor sets them right or clears them out.
A document built from a downloaded template often carries the original author name in its properties. A client who opens the file sees the wrong firm. One edit to the Author field fixes it before the file goes out.
A PDF with no Title shows the filename in a browser tab and gives a search engine nothing to read. Setting a proper Title makes the file look right and helps it surface in a search.
The properties can hold a name, a username, an organization and the software that made the file. Clearing every field before a public release keeps those fingerprints off the document.
Drop a document onto the panel above, or click to browse. The current properties load into the form under a Metadata loaded notice, and Reload Metadata brings them back from the file at any point.
Type into Title, Author, Subject, Creator, Producer, Language, Keywords (comma separated) and the two ISO dates. Reset All empties every field in one click when the properties should go.
Save Metadata to PDF writes the form into a copy named after the file with -updated on the end, and Download Updated PDF saves it. The original stays untouched and the visible page is unchanged.
To edit PDF metadata is to change the hidden properties that describe a file, not the page it shows. Here that means nine fields in a form and a Reset All.
Set or change the Title, Author, Subject, Keywords, Creator, Producer and Language, along with the creation and modification dates in ISO form. These are the fields every PDF reader and file system shows, loaded from the file the moment it lands on the panel.
A PDF keeps metadata in the Info dictionary and again in the XMP stream. Writing only one leaves the other stale, so a change here is put into both and the two never disagree.
Reset All empties every field at once, the author name, the software fingerprint and the timestamps included, and Save Metadata to PDF writes the blank form. It is the fast way to anonymize a legal, medical or financial file before it is shared.
The Title is what a browser tab shows and what a search engine looks at first. A clear Title with matching Keywords is a small piece of PDF SEO, helping a document look professional and surface in a search.
A PDF metadata editor, a PDF properties editor and a document information tool all name the same job. A fresh copy carries the new values and the original is left exactly as it arrived.
These are the properties the online PDF metadata editor loads and where they live inside the file.
| The field | Store | What it holds |
|---|---|---|
| Title | both | The document name shown in a browser tab and read by a search engine ahead of the filename. |
| Author | both | The person or organization credited with the document. Often left over from a template. |
| Subject | both | A short description of the content, used by some readers and accessibility tools. |
| Keywords | both | Terms that help a file surface in a search or a document management system, typed comma separated. |
| Creator | both | The application that made the source content, like a word processor. |
| Language | both | The document language as a code like en-US, which a screen reader and a search engine both use. |
| Producer | both | The application that wrote the PDF, which can reveal the software and its version. |
| Dates | both | The creation and modification timestamps, typed as an ISO value like 2026-04-11T12:00:00.000Z for an archive record. |
| Info dictionary | legacy | The original store from PDF 1.0, a handful of simple string fields most tools show. What a PDF keeps after an edit explains why an old value can linger. |
| XMP stream | modern | An XML store built on Dublin Core that mirrors the same fields and can hold custom and rights properties, required by PDF/A. |
Changes the Properties, Not the Page
Metadata is the hidden set of properties that describe a PDF, the Title, the Author, the Keywords and the dates, held in two places at once. Editing them fixes a wrong name, sets a Title that looks right in a search or clears every field before a document is shared. None of it alters the visible page or its layout. Because a PDF stores the same properties in the Info dictionary and again in the XMP, a change written to only one leaves the other stale, so both are updated together here. Metadata is for organization and privacy rather than security, since anyone with an editor can change it. The standards below define where it lives.
Both change the properties of a PDF. The two differ in price, in how many files go through per run and in what sits beyond the standard fields.
| Point of comparison | This tool This PDF metadata editor On the device | Hosted suites Metadata bundled with an editor and a plan |
|---|---|---|
| Where the document goes | Never leaves the device | Uploaded to a server |
| Writes both stores | Info dictionary and XMP | Often the Info dict only |
| Price | Free with no cap | Free tier often capped |
| An entire library at once | One PDF per run | Batch on their hardware |
| Custom XMP schemas | Nine standard fields | Rights and custom tags |
The last two rows go to the hosted suites, since a batch across a library and custom XMP schemas both suit a server with a plan behind it. The price row goes to this PDF metadata editor, free with no task cap against a hosted tier limited to a few tasks an hour. Browser-based file tools weighs the rest of the trade.
The metadata is read and rewritten inside the browser, so the document and every property in it stay on the machine that opened them. Nothing is sent away to be tagged.
With metadata the detail being changed is often the identifying part, an author name or an organization. A hosted editor uploads the file to a server to read those fields, which is the opposite of what stripping them is meant to do.
Every one of these can change a document property. They differ in reach, in cost and in the effort involved.
Acrobat needs a plan, ExifTool a terminal, a script a programmer and the file manager stops at the basic fields. The online PDF metadata editor above needs none of those and loads all nine fields into one form.
Three small checks before the online PDF metadata editor saves anything.
Editing metadata sets the hidden properties only. The words, images and layout on the page stay exactly the same, so a wrong Title is fixed without reflowing a single line of content.
A name removed from the Info dictionary can still sit in the XMP behind it. Stripping a field means clearing it in both places, so a Reset All is worth a check in the reader afterwards.
Anyone with an editor can change a property, so metadata records and organizes rather than protects. For real protection of the content itself, a password or true redaction is the right tool.
The online PDF metadata editor handles one document per run. A folder of reports that all need one Author, or a merged set with clashing titles, is work for the desktop edition, which works from disk and rewrites the metadata on every file in one pass.
Point it at a directory and one Author, Creator or Title is written across every PDF in a run, every file saved beside its source.
Beyond the standard fields, custom XMP schemas and rights tags can be set for a document management or publishing workflow.
Creation and modification dates can be set in bulk to match a publication timeline for a legal or compliance archive.
Free, with no sign-up and no watermark. Set the Title, Author and Keywords in the online PDF metadata editor, or clear them for privacy.
