Edit or clear the metadata inside a PDF
Every PDF carries a little passport: who made it, in which app, and often the internal title of the document. It travels with the file wherever you send it.
How PDF Metadata Editor works
The file is read with a FileReader, rewritten in memory and offered as a download. This is why large PDFs are limited by your device's RAM rather than by an upload size limit. A 200 MB scan never crosses the network, so the slowest part is your own disk.
That is the whole architecture: static files, one script, no upload endpoint to leak or log. Close the tab and the work is gone.
Good to know
- Works offline once loaded, including on flights and in locked-down networks.
- No file size limit beyond your device's own memory.
- Free to use, with no account and no usage counter.
- Results are produced locally, so they are not logged or shared with anyone.
Questions
What does it change?
Only the document information dictionary — title, author, subject, keywords, producer and creator. Pages, fonts and layouts are not re-rendered.
Does the producer really disappear?
The original value does. The PDF engine this tool uses stamps itself as Producer when it writes the file, so the field ends up with the library name rather than the application you used. That is still the win: the field no longer names your editor, its version or your internal toolchain. Title, author, subject and keywords are cleared outright.
Is the text still selectable?
Yes. Unlike compression, this does not rasterise anything.
Does it remove XMP metadata too?
No. Some files carry an additional XMP block that needs a different tool. Clearing the info dictionary removes what most readers display.
