From Wikipedia, the free encyclopedia
This is a list of links to articles on software used to manage Portable Document Format (PDF) documents. The distinction between the various functions is not entirely clear-cut; for example, some viewers allow adding of annotations, signatures, etc. Some software allows redaction, removing content irreversibly for security. Extracting embedded text is a common feature, but other applications perform optical character recognition (OCR) to convert imaged text to machine-readable form, sometimes by using an external OCR module.
- Creators – to allow users to convert other file formats to PDF.
- Viewers – to allow users to open, read and print PDF files.
- Editors – to allow users to edit or otherwise modify PDF files.
- Converters – to allow users to convert PDF files to other formats.
