What is PDF metadata and why should I change or remove it?

PDF metadata contains hidden document properties such as the author's real name, company name, creation dates, software software version, and computer filepath tags. Changing or removing metadata prevents accidental privacy leaks before publishing files.

Can I remove my name and company details completely from a PDF?

Yes! Click our 'Wipe All Metadata (Anonymous Privacy Mode)' button to strip away all author names, producer tags, subject lines, and creation timestamps in a single tap.

Does changing metadata alter the visual text or pages of my PDF?

No. Editing metadata only modifies hidden document header properties. Your PDF's visual layout, page images, vector text, fonts, and formatting remain 100% untouched.

How do PDF keywords and titles improve SEO ranking in search engines?

Search engines like Google index PDF document titles and keywords tags. Setting descriptive titles and target keyphrases helps public eBooks, research papers, and whitepapers rank higher in search results.

Can recipient software see previously wiped metadata?

No. Once wiped and exported with SlowPDF, the hidden dictionary tags are permanently overwritten in the exported file structure.

How do I change the PDF title that displays in browser tab titles?

Upload your file to SlowPDF, enter your preferred document title into the 'Document Title' field, and click 'Save & Update Metadata'. Browsers will display this updated title in tab headers.

Are my files uploaded to your servers during metadata editing?

Never. All document parsing and metadata modifications happen 100% inside your local device's browser RAM using WebAssembly and pdf-lib. Zero data leaves your physical device.

Can I edit the creation and modification date of a PDF?

Yes! You can pick any custom creation date using our date selectors or click 'Set to Today' to sync timestamps instantly.

Does this tool work on mobile devices and tablets?

Yes! SlowPDF's metadata editor is fully responsive and optimized for mobile screens with a sticky action dock.

Is SlowPDF 100% free with no watermarks?

Yes! SlowPDF is 100% free with zero watermarks, zero limits, and zero registration requirements.

Published by SlowPDF Technical Security Team • 100% Privacy Guaranteed

Understanding Hidden PDF Metadata & Security Risks

Every PDF document created by desktop software like Microsoft Word, Adobe Acrobat, Google Docs, or Apple Pages contains hidden metadata stored inside its header dictionary. This hidden metadata automatically records sensitive personal details including the author's real name, company organization, exact creation date, software software version, computer file path tags, and machine ID codes.

When sharing sensitive legal contracts, corporate financial statements, investigative journalist reports, or academic research papers publicly, failing to inspect and clean hidden metadata poses significant data breach risks. Unwittingly leaking author identities or internal folder paths can compromise client confidentiality and organizational privacy.

How to Edit PDF Metadata in 3 Simple Steps

Upload Your PDF Document: Drag and drop your file into SlowPDF's Metadata Studio. Our auto-extraction engine instantly parses existing document properties.
Modify or Wipe Properties: Edit fields such as Document Title, Author, Subject, and Keywords—or click "Wipe All (Anonymous)" to strip hidden personal tags instantly.
Save & Download: Click "Save & Update Metadata". SlowPDF embeds updated properties directly into browser RAM and exports a pristine PDF file.

Why SlowPDF is the Best Private Metadata Editor

Traditional PDF metadata editors require uploading confidential PDF documents to third-party cloud servers. Those remote servers store copies of your files on cloud disks, exposing your confidential papers to server leaks and unauthorized web tracking.

SlowPDF guarantees 100% private in-browser RAM execution. Operating via client-side JavaScript WebAssembly and pdf-lib, all dictionary parsing and property setting happen exclusively inside your physical device's local memory. Zero bytes touch a remote server, ensuring total confidentiality for legal, financial, and personal records.
