PDF Metadata
View and edit a PDF's title, author and keywords โ or blank them.
About this editor
Load a PDF and its metadata fields appear for editing โ title, author, subject, keywords โ along with the read-only trail (creator app, producer, creation date). Save with new values, or hit Blank all fields before sharing something sensitive. All local, original untouched.
What metadata does, and what it leaks
The constructive side: the title is what browser tabs, search results and screen readers announce โ a file named final_v3(2).pdf can still present itself properly, which is accessibility and SEO in one field. The leaky side: author fields routinely carry real names harvested from OS accounts, and producer strings reveal the software chain โ famously awkward in legal and corporate documents. The honesty this tool insists on: blanking covers the standard info dictionary, but some producers also embed an XMP metadata stream that can retain copies โ so for genuinely sensitive redaction, dedicated tools and a hex-level check are the standard, and the hex viewer will show you exactly what survived. Images carry the same double edge in EXIF โ that story and its viewer are the photographic siblings.
Frequently asked questions
What shows a PDF's title instead of its filename?
Browser tabs, search-engine listings and screen readers all prefer the metadata title. Setting it turns 'final_v3(2).pdf' into a properly named document everywhere it appears.
What personal data can hide in a PDF?
Author fields often carry the OS account's real name; creator/producer strings name your software; creation dates timestamp your work. Blank all fields clears the standard set before sharing.
Does blanking metadata guarantee anonymity?
Not fully โ some tools embed a second copy in an XMP stream that basic editing can miss, and the tool says so honestly. High-stakes redaction needs dedicated software and verification.
Is the file uploaded to read its metadata?
No โ reading and rewriting happen in your browser; the file never leaves your device, and your original on disk is untouched.
