一张手机原图动辄四五 MB，微信会替你压、邮件会替你拦，最后到对方手里什么样，你其实控制不了。不如自己先压一遍。A phone photo is four or five megabytes; WeChat compresses it, email rejects it, and what the other side finally sees is out of your hands. Better to do it yourself first.
合同、扫描件、报价单凑成一份发出去，真正麻烦的从来不是「生成 PDF」，而是最后那几步：顺序、页码、水印、签名，还有对方到底能不能打开。Merging a contract, a scan and a quote into one file is easy; the last mile — order, page numbers, watermark, signature, and whether the other side can even open it — is the part that bites.
单张照片是记录，一组照片才是叙事。切九宫格、拼长图、做四连拍，本质上都是在解决同一个问题：怎么让几张图连起来读。One photo records; a set of photos tells. Grid crops, long images and photo strips all answer the same question: how do you make several images read as one.
想留孩子说的一句话、想把会议结论那三分钟单独发给同事，打开剪辑软件太重，找在线工具又要先上传。其实这四件事在浏览器里就能做完。Keep the one funny line your kid said, send the three minutes of conclusions to a colleague — a full editor is too heavy, and online tools want an upload first. These four jobs can be done in the browser.
