Quick Actions
Three steps. Under 30 seconds. No signup, no upload.
A complete metadata editor built for speed, privacy, and ease of use.
Edit title, author, subject, keywords, creator, and producer. Each field has validation, character limits, and live counters.
Everything runs in your browser. No uploads, no servers, no data collection. Your files and metadata stay completely private.
Metadata is read and written in milliseconds using pdf-lib. No waiting for server round-trips. Even 100 MB PDFs process in seconds.
A real-time completeness ring shows which fields are filled. Aim for 100% to maximise document discoverability.
Export metadata as JSON for records, or import metadata from another PDF to apply the same properties across multiple documents.
Strip all metadata from a PDF with one click. Ideal for privacy, sharing sensitive documents, or preparing files for publication.
PDFcrest's metadata editor processes everything locally inside your browser using JavaScript and WebAssembly. No file data, metadata, or personal information ever reaches our servers.
Whether you're publishing documents, managing records, or protecting your privacy, editing PDF properties is a practical skill for many roles.
Set accurate title, author, and subject fields before distributing eBooks, reports, or papers. Proper PDF document properties improve discoverability in online libraries and search results.
Strip sensitive creator or software metadata from legal documents before sharing with clients or courts. Ensure confidential authoring information isn't inadvertently disclosed in PDF properties.
Add keyword-rich PDF metadata to whitepapers, case studies, and brochures to improve search engine indexing. Google and Bing index PDF titles and subjects — well-tagged PDFs rank higher.
Standardise metadata across large document collections. Use consistent subject and keyword tagging so enterprise document management systems and digital archives can accurately categorise and retrieve files.
PDFs created in Microsoft Word, Google Docs, or Adobe Acrobat often embed your real name, company, and computer username in the metadata. Remove all metadata before sharing sensitive files publicly.
Use the JSON export feature to extract metadata from multiple PDFs programmatically, or bulk-apply consistent properties. The JSON import lets you reuse one metadata template across an entire document library.
Understanding the six standard PDF document properties helps you fill them correctly and maximise document discoverability.
The document's official name. Search engines index this field prominently — a descriptive title like "2024 Annual Marketing Report" improves PDF search ranking more than a generic "document1" filename. Limit: 200 characters.
The person or organisation responsible for the content. Used by citation managers (Zotero, Mendeley), academic databases, and document management systems. For privacy, clear this field before sharing externally.
A brief summary or category description of the document. Think of it as a subtitle or abstract — "Q3 Financial Results" or "Product Safety Guidelines". Enterprise DMS tools use this to auto-categorise incoming files.
A comma-separated list of search terms relevant to the document. Google and Bing use these when indexing PDFs. Use long-tail keyword phrases — for example "change pdf metadata online, edit pdf properties, pdf document properties editor". Limit: 500 characters.
The application that originally authored the document — e.g. "Microsoft Word 365", "Adobe InDesign", or "Google Docs". Editing this field is common when anonymising documents or correcting inaccurate software strings left by older authoring tools.
The PDF conversion software — e.g. "Adobe PDF Library 23.1", "Ghostscript 10.0", or "PDFKit". Often reveals which internal tools your organisation uses. Remove this for competitive or privacy reasons before publishing documents externally.
Practical guidance to get the most out of your PDF document properties.
Search engines like Google give weight to a PDF's Title field. Instead of "Report_v3_final", use "2024 Q3 Revenue Report — PDFcrest Finance". Include the primary keyword once in the title and once in the subject for best SEO results.
PDFs generated by Word and Google Docs often include your real name, employer, and revision history in the metadata. Before emailing contracts, medical records, or legal documents to external parties, use Remove All Metadata and verify the properties panel shows empty fields.
If you need to apply the same metadata to multiple PDFs — for example, tagging 20 documents with the same company, year, and keyword set — export the metadata as JSON from one finished document, then use Import from PDF to copy those exact properties onto each subsequent file.
The real-time completeness ring tracks how many of the six editable fields are filled. Documents with complete metadata are more likely to be correctly indexed, cited, and retrieved in document search systems. Aim for 100% for any document intended for public distribution or long-term archiving.
Password-protected PDFs cannot have their metadata edited until decrypted. Use the Unlock PDF tool to remove the password, then edit and update the metadata. Re-apply password protection with the Protect PDF tool after.
PDF properties affect how your documents appear in search results, document management systems, and PDF viewers. Here is what you need to know.
Google indexes PDF files the same way it indexes web pages. The Title you set in the metadata editor becomes the clickable headline in search results. The Subject and Keywords fields add topical signals. A PDF with a blank or auto-generated title like "Untitled" is a missed ranking opportunity — edit PDF metadata to take control of how your document appears in Google and Bing.
Enterprise DMS platforms — SharePoint, Documentum, OpenText, and others — use PDF properties to auto-classify, tag, and route documents. If Title or Author fields are empty or inaccurate, files end up miscategorised or lost. Using this PDF properties editor before uploading to a DMS ensures every document is correctly indexed and retrievable without manual tagging.
PDFs created in Microsoft Word, Google Docs, and Adobe Acrobat automatically embed your name, organisation, computer username, and the exact software version used. Sending a document externally without reviewing these fields can inadvertently expose confidential authorship details. Use Remove All Metadata to strip creator and producer fields before sharing sensitive legal, financial, or HR documents.
Open this page in Chrome or Edge, upload your PDF, edit the properties, and click Update PDF. Alternatively, right-click any PDF → Properties → Details tab to view (but not edit) metadata. Adobe Acrobat Pro can edit properties via File → Properties, but requires a paid subscription.
Use this browser-based PDF metadata editor in Safari or Chrome — no installation needed. Preview (built-in) can display metadata via Tools → Show Inspector but cannot edit PDF document properties. Use this tool to change PDF title, author, subject, and keywords on any Mac without Acrobat.
Open this page in Safari (iPhone) or Chrome (Android) and upload your PDF from Files or Google Drive. The browser-based editor runs fully on mobile — tap fields to edit, then tap Update PDF to save. No app download required to edit PDF properties on iPhone or Android.
Open this page in Chrome, upload your PDF, and use the metadata editor directly. The tool runs entirely in the browser — no Linux apps, Android apps, or file system access needed. Ideal for Chromebooks in education or enterprise environments with restricted software installs.
