View and edit your PDF's metadata
Every PDF carries hidden document information — title, author, subject, keywords, the creator/producer software and the creation and modification dates. This tool reads those fields, lets you change or clear them, and saves a new PDF. It all runs in your browser; your file is never uploaded.
Why metadata matters
- Searchability & organisation — a proper title and keywords help find the file later.
- Professional polish — the title often shows in the browser tab and search results.
- Privacy — exported PDFs can leak your name or software in the author/creator fields, and the dates reveal when you actually worked on the file. Clearing them before sharing is good practice.
How it works
The fields are read from the document's Info dictionary and written back with an open-source library (pdf-lib). Empty a field and save to remove that value; the same applies to the creation and modification dates. The page content is never touched — only the document information changes.
Removing everything at once
The Remove all metadata button clears, in one step, every entry of the Info dictionary — including vendor-specific extras such as company, department or source file name — both dates, and every XMP stream.
XMP is a second metadata layer inside the same document, and many viewers prefer it over the Info dictionary. Clear only the visible fields and leave XMP in place, and you hand out a file that looks empty in one layer while the viewer still shows the old title and author in plain text. That is why XMP is removed here as well.
What still stays in the file
Two things cannot be removed without rebuilding the pages:
- Embedded attachments, together with their own metadata.
- EXIF data inside embedded JPEG images, such as camera model or capture location.
If your file contains either, the tool names it explicitly instead of letting you believe the file is clean. When a scanned image is the cause, the redact or compress tool helps: both rebuild the affected pages as a fresh image and leave the original JPEG, EXIF included, behind.
Private by default
Reading and writing happens locally on your device — nothing is sent to a server, so even sensitive documents stay private. It works offline.
