Free PDF Metadata Editor Online

Document Info stores descriptive properties separately from visible pages: title, author, subject, keywords, creator, producer, and creation and modification dates. This PDF metadata editor reads those eight fields into a form and writes your changes into a new copy. Blank fields stay blank; the tool does not infer an author or title from page content.

Title, author, subject, and keywords help identify a document. Creator usually names the originating application; producer names the software that generated the PDF. Applications may rewrite dates during export. These descriptive values do not prove authorship, ownership, publication time, legal status, or who last changed the file.

The PDF metadata editor does not change visible text, images, page order, OCR, permissions, or annotations. It creates a separate output after checking the requested Document Info changes; your source file is not edited or renamed in place.

A PDF may contain Document Info, XML-based XMP, both, or neither. Their values can conflict, and a reader or publishing system may prefer one source. Updating Document Info therefore does not update every metadata value in the file.

This PDF metadata editor preserves existing XMP and reports detectable document or page XMP separately. It does not expose individual XMP properties for editing. An old author or title can remain in XMP even after you correct the corresponding Document Info field.

Use the remover to clear the complete Info dictionary and detectable document/page XMP references, or the viewer for a read-only report. Detailed XMP editing, archival profiles, embedded assets, and custom objects require specialist software and verification against your workflow requirements.

Open a copy of the exact PDF you intend to publish. In the PDF metadata editor, keep useful fields, correct inaccuracies, and clear values only when your publishing policy requires it. A later export can replace your edits. Metadata presence alone does not indicate a privacy problem.

Write a descriptive title, use the intended author attribution, and avoid private project labels in keywords. Creator, producer, and dates may support troubleshooting or records management. Confirm legally or archivally significant values with the document owner before changing them.

After saving, the tool reparses the output and checks each requested Document Info value. Download it, inspect its pages and properties in your usual reader, and keep the original until your review passes. Recheck after later printing, merging, conversion, signing, or uploading, which can introduce new metadata.

The PDF metadata editor needs no account and processes files in browser memory without uploading them. This does not replace device security: downloaded copies may still be indexed, backed up, synchronized, or shared by your operating system, browser, cloud folder, or other software.

Encrypted or password-protected PDFs fail fast because the editor has no decryption feature. Use an authorized decryption workflow first and follow the document owner’s policy. When a signature field is detected, the tool allows supported read-only inspection and disables writing. Rewriting a signed PDF can invalidate the signature or change its verification status, even when the visible content appears unchanged.

The browser accepts one PDF up to 25 MB, with no folder batches or saved history. Successfully replacing the file or closing the tab clears the current work. Complex, regulated, or legally sensitive documents may require an approved desktop workflow and audit trail.

Choose the PDF metadata editor when supported Document Info values should remain useful but need correction. Typical tasks include replacing an inaccurate title, updating an author label, revising a subject, removing stale keywords, or normalizing creator, producer, and date fields. The editor keeps existing XMP and creates a verified output, making it suitable for precise changes within a known boundary.

Choose the viewer when you need a read-only report. It shows the supported Document Info fields, page count, Info entry count, detectable document and page XMP presence, and signature-field status without creating a rewritten file. Inspection is often the best first step because it helps you see whether any supported value actually needs attention and whether a signed-file boundary applies.

The remover clears complete Document Info and detectable document/page XMP, then verifies their absence. None of these tools guarantees forensic sanitization: attachments, annotations, visible content, OCR, custom objects, historical revision data, and external records need separate review.
