Working with text has never been this fast and easy.

Getting tired of looking for online tools to do simple string conversions for you? Not sure what happens with your strings when uploading them to some random website?

Convert String easily converts any of your strings into the desired string. Currently the following features are included:

• Lower- or uppercasing, capitalizing, and reversing
• AP, APA, CMOS, and MLA style formatting
• Encoding and decoding Base64, Hex, HTML, and URL
• Encoding and decoding ROT-5, ROT-13, ROT-18, and ROT-47
• Hashing to MD5, SHA1, SHA224, SHA256, SHA384, and SHA512
• Replacing characters or words within strings
• Sorting (and reverse sorting) with selectable separators
• Viewing a history of all conversions
• Exporting to CSV, JSON, or XML

We respect your privacy. Nothing you enter into Convert String ever leaves your Mac. Convert String does not phone home.

We are sure you'll love Convert String as much as we do. It'll fit into your workflow effortlessly.

If you have any suggestions or if you have found a bug we should take care of, don’t hesitate to shoot us an email at
