做了个纯前端的 ASCII 工具站:图片转字符画、banner 生成、符号一键复制 平时偶尔需要查 ASCII 码表、复制一些特殊符号(箭头、制表符这类),每次都是搜一个满屏广告的老站凑合用,索性自己做了一个: https://getascii.com 目前有这些工具: 图片转 ASCII 字符画(拖一张图进去就行,支持调宽度/字符集/反色) 文字转 ASCII banner 大字 常用符号一键复制(箭头、制表符、数学符号、颜文字) 完整 ASCII 码表 + 一个交互式键盘映射图(点键盘上的键显示对应的 dec/hex 码) 进制转换器( hex/dec/bin ↔ ASCII ) 几个实现上的点: Astro 构建的纯静态站,所有工具都是纯客户端计算,图片不会上传到任何服务器 没有账号系统,没有付费墙,打开就用 整站是绿色荧光终端风( CRT 扫描线 + JetBrains Mono ),算是给终端审美交个作业 顺手给它做了个 25 秒的宣传片: https://www.youtube.com/watch?v=AjzU5mw1PrI
