How your files are handled

We built these tools so you never have to wonder where your documents go. Here is exactly what happens when you use them.

  • Your files are processed entirely in your browser using open-source libraries (pdf-lib, PDF.js, and others).
  • Nothing is uploaded to our servers. We have no backend that receives, stores, or scans your documents.
  • We cannot see, store, or access your files — not during processing, not after, not ever.
  • Processing uses your device's memory and CPU. Large files may take longer, especially on phones and tablets.
  • All tools are free with no paywall tricks, no hourly task limits, and no watermarks on your output files.

How it works

Three simple steps. Your files never leave your device, and the result downloads straight to your computer or phone.

How to edit Metadata

Edit Metadata changes a PDF's document properties, including the title, author, subject, keywords, and creator. It is useful for tidying up file details before sharing or archiving.

  1. Add your PDF; its existing metadata is read on your device with no upload.
  2. Edit the title, author, subject, keywords, or creator fields, which are pre-filled with the current values.
  3. Click Save metadata to write the new properties.
  4. Preview and download the updated PDF.

Everything happens in your browser — your file is never uploaded, and there is no sign-up, watermark, or limit.

Frequently asked questions

Are my files uploaded to a server?

No. Every tool runs entirely in your browser using open-source libraries, so your file is processed on your own device and is never uploaded. We have no backend that receives, stores, or scans your documents.

Is it really free, and will there be a watermark?

Yes. There is no account, no sign-up, and no hourly limit, and the tools never add a watermark to your output. UnboundPDF is free and is not affiliated with Adobe.

Does it work on a phone or tablet?

Yes. The tools run in any modern mobile browser as well as on desktop. Because the work uses your device's own memory and processor, very large files simply take longer on phones.

Can I see what metadata is already set?

Yes. The fields load pre-filled with the document's current title, author, subject, keywords, and creator so you can review and edit them.

Does this change the visible content of my pages?

No. Only the document's hidden properties change; the pages themselves stay exactly the same.
