How to use the encoding converter?
Select source encoding (or use auto-detect) and target encoding, enter the text to convert, then click the convert button. You can also use quick convert buttons for one-click common encoding conversions.
How does auto-detect work?
When "Auto Detect" is selected, the tool tries multiple common encodings (UTF-8, GBK, Big5, Shift_JIS, EUC-KR) to decode the text and automatically identifies the most likely source encoding. If auto-detect is inaccurate, you can manually select the source encoding.
How to convert GBK to UTF-8?
Click the "GBK → UTF-8" quick button, or select GBK as source encoding and UTF-8 as target encoding, enter GBK-encoded text, then click convert. You can also use auto-detect, and the tool will automatically identify GBK encoding.
How to convert Big5 to UTF-8?
Click the "Big5 → UTF-8" quick button, or select Big5 as source encoding and UTF-8 as target encoding, enter Big5-encoded text, then click convert. You can also use auto-detect, and the tool will automatically identify Big5 encoding.
How to fix garbled text?
