Converters

Free converters for the file types and data formats you deal with every day. Change JSON to YAML, encode or decode Base64, or fix text that came out with broken line breaks. Everything runs in your browser, so your data stays on your device and there is no upload wait. These tools are built for quick jobs: check a config file, clean up copied text, or prepare data for a form. Each one shows the result right away so you can copy it and move on. Some also let you download the output as a file. Pick a converter below. You do not need to sign up, and there is no cap on how much you convert.
