Yes, Xodo is a PDF editor, but it is not a word-processor (like Word or Google Docs).
Examples of currently supported editing operations:
- Create/edit/delete annotations.
- Insert/delete/rotate/move/crop pages.
- Insert/edit bookmarks.
- Merge PDFs.
- Convert image, text, office, and other formats to PDF.
- Fill-in and edit PDF forms .
- Add blank pages, place images, text/notes, and scribbles.
- Sign documents.
- Reduce file size and optimize existing PDF documents.
- Flatten forms, signatures, and annotations so that they are not 'editable'.
- Encrypt or remove PDF security on existing documents
- and much more
Due to the nature of the PDF file format (a fixed page document missing a universal semantic structure), there is no app that can reliably edit PDF documents in a manner similar to a word-processor. Some apps may claim (or appear) to work in very basic cases, however there is no reliable or a general purpose solution. Also we don't expect that this will change in the near future.
