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
