Edit PDF Metadata

Edit selected document-info properties stored in a PDF.

Processing

The PDF is read and updated in browser memory; this workflow does not send the document to a Stocknivo conversion endpoint. This is an application-level processing description, not a promise of fully offline use or a production security audit.

How it works

Choose one PDF, edit its title, author, subject, or comma-separated keywords, then save and download the result. Creator, producer, and date values are shown as read-only information.

Limits and unsupported metadata

The input may be up to 50 MiB and output is limited to 100 MiB; no artificial page-count ceiling is imposed. Title, author, and subject accept up to 1000 code points each; keywords accept up to 5000. This editor covers these document-info fields only; it is not a comprehensive XMP or advanced-metadata editor.
