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

I built a mobile workspace to edit and preview the HTML apps ChatGPT/Claude write for you. Hey everyone! I built VanillaPad , a mobile workspace for building simple HTML/CSS/JS projects. 👉 https://vanillapad.dev The idea came from something I kept running into. Sometimes I'd need a simple utility app or a quick landing page or to test a little game idea. Getting the initial code written was easy since I could just ask ChatGPT or Claude on my phone. The hard part came af

最近对网站进行了重构,做成了免费的视频工具站:[ArtPlayer Tools]( https://artplayer.org/tools/) 主要是围绕着 ffmpeg.wasm 和 mediabunny 实现的一些可以直接在浏览器里用的视频/音频工具,常用的有: - 视频压缩:[Compress Video]( https://artplayer.org/compress-video/) - 视频裁剪:[Crop Video]( https://artplayer.org/crop-video/) - 视频合并:[Merge Video]( https://artplayer.org/merge-video/) - 视频尺寸调整:[Resize Video]( https://artplayer.org/resize-video/) - 视频旋转:[Rotate Video]( https://artplayer.org/rotate-video/) - 视频调速:[Change Video Speed]( https://artplayer.org/change-video-speed/) - 添加文字到视频:[Add Text to Video]( https://artplayer.org/add-text-to-video/) - 添加水印:[Watermark Video]( https://artplayer.org/watermark-video/) - 提取字幕:[Subtitle Editor]( https://artplayer.org/subtitle-editor/) - HLS 转 MP4:[HLS to MP4]( https://artplayer.org/hls-to-mp4/) - 音频可视化:[Audio Visualizer]( https://artplayer.org/audio-visualizer/) 大部分工具都是本地处理,文件不会上传到服务器。最开始是因为自己偶尔要处理一些视频,开剪辑软件又有点重,在线工具又担心隐私,所以就慢慢做成了一个站。 目前还在持续完善,体验肯定还有不少粗糙的地方,比如不同浏览器的兼容、移动端操作、长视频性能之类的。 网站: [ArtPlayer Tools]( https:
