How does Edit metadata work on MakeOverPDF?

Change the title, author, subject and keywords a document reports. MakeOverPDF runs qpdf --update-from-json on the server and returns: One PDF, downloaded immediately.

Is Edit metadata free and private to use?

Yes. MakeOverPDF requires no user account, watermarks nothing unless you use the watermark tool, and deletes your uploaded document from the private working directory as soon as the request finishes.

What are the file size and page limits for Edit metadata?

Four fields are written: title, author, subject and keywords. A field you fill in is set; a field you leave blank is removed from the document. Everything else it reports — the producing application, for instance — is left alone. A PDF carries its metadata twice: this information dictionary, and an XMP stream that some publishing and search tools read instead. XMP cannot be rewritten with the engines this server has, so an edit removes it rather than leaving the old story beside the new one. An edited document reports one version of itself; nothing that needs XMP will find it afterwards. The result is read back before it is offered: the four fields are re-read with an independent reader, the page count is compared with the input, and the absence of the XMP stream is confirmed on the produced file.

Edit metadata

Change the title, author, subject and keywords a document reports.

Run this tool

The file is processed on this server and deleted as soon as the response is sent. Nothing is stored, and the result is returned directly to you rather than parked behind a link.

The document

Choose a PDF to edit Up to 25 MB. The file's contents are checked, not just its name.

What the document should report

Title What the document is called.

Author The person credited with the document.

Subject A short description of what it covers.

Keywords Comma-separated search terms.

Only what you type is kept: any field you leave blank is removed from the document. Enter at least one.

The document's XMP metadata stream, if it has one, is removed rather than left stale, so every reader reports the same story.
