File viewer / text encoding conversion utility for Mac OSX

Peep is a 'hexeditor'-style native OSX app with the emphasis on text encoding.

There are many different text encoding systems (ways of representing characters within a file) and a file doesn't necessarily know what encoding it's in. This can lead to frustrating problems when the file is opened.

Peep is useful when programming, when experiencing text encoding problems or when you need to extract information from a file that you can't open otherwise.

Allows you to view files in a 'hexeditor' style, it's not intended to be an editor but rather to inspect, access or sort out encoding problems.


If you have a problem or suggestion, please see Peep's help page for contact details.
