Frequently Asked Questions
What is the fastest way to edit PDF properties client-side?
Using our 100% free online PDF metadata editor is the fastest way to manipulate document properties. Because the tool uses advanced client-side processing (via WebAssembly and JS), your file never leaves your browser. This means zero upload wait times and immediate downloads when changing the title, author, or keywords.
How to change a PDF author name for free?
Simply drag and drop your PDF into the tool above. Our system will instantly extract the hidden properties. Locate the "Author" input field, type your new desired author name (or delete it to make it anonymous), and click the Update button. The modified PDF is generated locally on your device for free.
How to remove metadata from PDF files securely?
If you need to securely scrub a document before sending it to a client or public portal, upload it here and click the red "Clear All Data (Scrub)" button. This instantly wipes out the Title, Author, Subject, Keywords, Creator Tool, and Producer history. Once downloaded, the document's hidden tracking footprint is effectively sanitized.
How can I fix a wrong PDF title showing in the browser tab?
When a PDF opens in Chrome or Safari, it often displays a strange title in the tab instead of the file name. This happens because the hidden "Document Title" metadata field was auto-generated incorrectly (often by Microsoft Word or a scanner). Upload the file to our tool, correct the "Title" field to match your desired name, save it, and the browser tab issue will be permanently fixed.
