Want to edit the metadata of your PDF files? There’s a new free open-source app to make the thing super easy!
Metadata is a small piece of data, such as author, creation date, type, that describes and gives information about the file that contain it.
For PDF files, it may be useful to edit the metadata for production use. And, here’s a simple application to do the job in Linux Desktop!

- Creation Date
- Modification Date
It’s so simple, that user just need to drag and drop PDF into app window, then start editing the data.
