写了个在线压视频的站，能压到指定大小，顺手聊两个踩坑 起因很土。给客户发一个 60 多 M 的录屏，Gmail 说超了 25M ，扔网盘对方公司的网又打不开。本机有 ffmpeg ，但每次都得去翻 crf 该给多少，笔记本风扇还要吼两分钟。想找个在线的，搜出来前几个一半给你打水印，一半让你先注册。 于是自己搓了一个： https://vidsmaller.com 先把话说在前面：编码这一层是买的第三方转码 API ，不是自建 ffmpeg 集群。剩下的东西（登录、额度、计费、下载代理、i18n 、后台）都是自己写的，Next.js + Drizzle + Supabase ，跑在 Vercel 上。 能干的事： - 直接填数字。要 18MB 就填 18 ，它按这个体积去编码，输出基本落在你要的值上 - Discord 20M 、WhatsApp 16M 、邮件附件这些常见上限做成了滑块下面的按钮，不用自己算 - 也能完全手调，CRF 、分辨率、最高码率都在高级里 - 不加水印，免费也不加 - 不登录就能直接试，单文件 500M 以内；注册了免费 30 次

I built an AI watermark remove and before you claim BS Read This I built an AI watermark remover called un-claude.com . Before you claim BS, I suggest you read this. I approached this from a very technical perspective and am transparent about my absolute claims in terms of what we can and can't positively guarantee. There are 3 kinds of AI watermark, and we can only positively claim we remove two of them. 1) Invisible characters - (Zero-width spaces, joiners, direction marks) We name

got sick of copy/pasting AI text into so I made it an agent skill lol now in Codex, Claude Code or Cursor you can just say “remove the watermarks from your last answer” and it does it inline.

I built a PDF redactor that auto-detects names, SSNs, and account numbers without sending your file anywhere - works on your phone too. Free, no sign-up. Plenty of redaction tools upload your file to their server first (no thanks for legal/medical/tax docs). Some keep the file local but send the text off to an AI, so the text still leaves. And most of the truly local ones only let you draw black boxes by hand, which is how those "redacted" documents in the news keep getting un-r
