Your files never leave your device

How to pdf metadata editor

  1. 1

    Choose your PDF file

    Click the upload area or drag files onto it. Nothing is uploaded — files are opened locally.

  2. 2

    Adjust the settings

    Pick title, author, subject, keywords, and other metadata, then press the convert button.

  3. 3

    Download the result

    Save each file individually or everything at once as a ZIP.

PDFs carry hidden properties — author name, software, creation dates — that can reveal more than you intend. Set a clean title for search engines and document managers, or wipe the metadata before publishing. Fields you leave blank stay as they are unless you choose to remove everything.

What is PDF?

PDF (Portable Document Format) preserves a document’s layout on every device and operating system, which makes it the standard for sharing, printing and archiving.

Is it private?

Yes. Unlike upload-based converters, ZapMorph processes files inside your browser tab, so the file stays on your device. It is never transmitted, stored or logged — close the tab and it’s gone.

Frequently asked questions

Is the pdf metadata editor converter free?

Yes. Convert 1 file a day without an account, or 5 files a day with a free account. Pro removes all daily limits.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser, so your files never leave your device. We only count how many files you convert — never their names or contents.

What is the maximum file size?

Up to 25 MB per file without an account, 50 MB with a free account, and 1 GB on Pro. Very large files also depend on your device’s memory.

Can I convert multiple PDF files at once?

PDF Metadata Editor works on one file at a time and can produce many output files, which you can download together as a ZIP.

Does it work on Mac, Windows, iPhone and Android?

Yes. It works in any modern browser — Chrome, Edge, Firefox and Safari — on desktop and mobile, with nothing to install.
