Frequently Asked Questions

What is character encoding?
Character encoding is a system that maps characters (letters, numbers, symbols) to numbers that computers can process. Different encodings use different mappings, which is why text can appear garbled when opened with the wrong encoding.
Why convert to UTF-8?
UTF-8 is the universal standard for text encoding on the web. It supports all characters from all languages and is compatible with most modern software. Converting to UTF-8 ensures your data displays correctly everywhere.
Is my data secure?
Yes! All processing happens entirely in your browser. Your files are never uploaded to any server. The conversion is done locally on your device.
What if the detection is wrong?
If the automatic detection produces incorrect characters, you can manually select the source encoding from a dropdown menu. Try common encodings like Windows-1252 for Western European text or Shift-JIS for Japanese text.
