Take control of how your document appears in libraries, search results, and email previews by rewriting its document information fields — processed locally in your browser with pdf-lib, so your file never leaves your device.
All standard document info fields: Title, Author, Subject, Keywords, Creator, and Producer. Fields you leave blank keep their existing values.
Many viewers prefer the embedded Title field once it exists — setting it here fixes what shows in tabs, readers, and search results.
No. Metadata editing is 100% offline — the PDF is processed in your browser memory and never sent anywhere. Encrypted files are skipped with a warning.
You can overwrite each field; set them to a single space to effectively blank them out.
