Images & photos The largest section, because "I have a picture and it is wrong somehow" covers a lot of separate problems. It is too big, the wrong format, the wrong shape, it has something in it you want to draw attention to, or it has data in it you did not know was there. 7 guides in this section.

The subtitle work is the substantial part: converting between the two formats that matter, diagnosing whether a file needs a constant shift or a frame-rate scale, merging two halves of a film and splitting one file in two. 2 guides in this section.
Data & spreadsheets CSV is a family of conventions rather than a format, which is why an export that one program writes happily is unreadable in another. The delimiter, the quoting style, the line ending and the character encoding are all places where two tools can disagree while both claiming CSV support. 2 guides in this section.
Everyday utilities Small jobs that are awkward everywhere else. Reformatting a block of text that arrived with hard line breaks. Counting it accurately when emoji are involved. Turning a link into something a phone camera can read. 3 guides in this section.
