Frequently Asked Questions
QHow do I remove extra spaces between words?
Enable "Collapse spaces" and every run of two or more spaces (or tabs) is reduced to a single space, while line breaks are preserved.
QCan it remove empty lines?
Yes. "Collapse blank lines" reduces multiple consecutive blank lines to one, and "Remove all blank lines" deletes every empty line.
QCan it join wrapped text into one paragraph?
Yes. Turn on "Join into one line" to replace all line breaks with single spaces — handy for un-wrapping copied PDF or email text.
