Why convert text in the browser
Pasted text can carry API responses, customer lists, or tokens. These tools work on the text inside this browser tab, so the input is not sent to a server, and the result is ready to copy or download as soon as it is made.
How the text and code tools work
- Pick the tool: JSON formatter, CSV JSON converter, QR code generator, or Base64 encoder decoder.
- Paste or type the text. Some tools can also open a file from your device.
- Choose the options, such as JSON spacing, the conversion direction, or the QR error correction level.
- Copy the result or download it as a file or PNG.
Frequently asked questions
- Is my text uploaded?
- No. The text and code tools process the input in your browser and do not send it to a server.
- Does Base64 encrypt my text?
- No. Base64 is an encoding, not encryption. Anyone can decode it, so do not use it to protect secrets.
- Can QR codes hold Korean text?
- Yes. The QR code generator encodes the text you enter, including Korean, and saves the code as a PNG file.
