做了个托管 PDF 的二维码工具 最近老婆一直在抱怨给老外传 pdf 文件很麻烦，之前一直是走邮件附件。麻烦在于文件一改就得重发一遍，对方手上可能还留着旧版本，来回确认到底看的是哪一版特别费劲。 想着不如给她生成个二维码或者短链接，文件更新了直接换后面的，链接不变。搜了一圈现成的工具，试了几家都有点别扭。有的免费能生成，点下载却要注册。还有的会在扫码后的落地页上放广告，但那是发给客户看的东西，不太合适。 干脆自己做了一个： https://qrcodeforpdf.app 传个 PDF ，出一个二维码和短链接，扫了在浏览器里直接打开，不用下载也不用装 App 。文件可以随时替换，码和链接都不变，已经发出去或者印出去的都还能用。不注册就能生成和下载，PNG 和 SVG 都没有水印，应该是比较完美的，刚好也作为自己的一个小项目，也欢迎大伙们试用给建议，逐步优化！

Building made me switch from Claude Code to Codex. Claude’s token usage was too expensive for my workflow. GPT-5.6 Sol + Codex lets me focus on building instead of watching usage limits. Loving it so far! 🚀 @OpenAI @thsottiaux
