TXT Encoding Converter

TXT编码转换是一款免费的在线开发工具，无需下载安装、无需注册登录，打开网页即可使用。它能读取 GBK、GB2312、GB18030、Big5、UTF-16 等多种编码的文本文件，统一转换并保存为通用的 UTF-8 编码，从根本上解决用记事本或其它软件打开 txt/csv/字幕文件时出现的中文乱码问题。「自动检测」会依次尝试常见编码，也可手动指定源编码。所有处理均在浏览器本地完成，文件不上传服务器。

TXT编码转换适用于修复从旧系统或 Windows 记事本导出的 GBK 乱码文件、统一团队协作时的文本编码、处理繁体 Big5 文档、转换字幕与日志文件编码等场景。转换为 UTF-8 后，文件在各平台和编辑器中都能正确显示中文。作为一款轻量在线工具，它随开随用，是开发调试与文档处理中的实用小工具。

常见问题
Q1：为什么要转 UTF-8？
A：UTF-8 是跨平台通用编码，转换后文件在各系统、编辑器、网页中都能正确显示中文。
Q2：能反过来转成 GBK 吗？
A：浏览器原生仅支持将各类编码解码为文本再输出 UTF-8，暂不支持输出 GBK；本工具专注于修复乱码、统一为 UTF-8。
Q3：文件会上传吗？
A：不会，读取与转换全部在浏览器本地完成。
Q4：自动检测不准怎么办？
A：可手动指定源编码（如 GBK、Big5）后重试，预览确认无误再下载。
Q5：转换后记事本打开还是乱码？
A：请确认用「UTF-8」方式打开；新版 Windows 记事本会自动识别，旧版可在「另存为」时手动选择编码。
TXT编码转换可以在手机上使用吗？
