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!
