Questions tagged [pdf-conversion]

Relating to converting between Portable Document Format and other file formats. Questions asking us to recommend or find a conversion tool or library are off-topic.

This tag is for questions relating to programmatically converting to and from the open standard file format . If a specific conversion is involved, the appropriate tag should also be used: etc.

Conversion solutions may range from complete rasterization (and graphic embedding) to intense . The middle ground generally converts at a high enough level to recognize and use text attributes where possible, falling back to graphic rendering only when necessary.

Questions asking us to recommend or find a tool, library, documentation or other off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam.
