Frequently Asked Questions
Can I change the "Title" that appears in the browser tab?
Yes. When you open a PDF in Chrome or Edge, it often displays the internal Title metadata instead of the actual filename. Editing the Title field with this tool fixes that issue instantly.
How do I change the Author of a PDF?
Simply load your file above, look for the "Author" input field, delete the existing name (e.g., "Microsoft Word"), type your name, and click Save.
Can I edit a Digitally Signed PDF?
Technically, editing breaks the signature. Digital signatures are mathematical proofs that the file has not been modified.
When you save changes with Lyonite, we automatically remove the invalidated signature so the file doesn't show a scary "Tampered" warning. You get a clean, edited copy, but the original "Signed" status is removed.
Are files uploaded to your server?
No. We use WebAssembly to process files on your device. Your files do not "travel" to us; instead, we send our code to your browser. You can even turn off your internet after loading the page, and the tool will still work.
