痛点：Mac 用户转换 HEIC/视频/文档时，被迫使用上传文件、广告多、有大小限制的在线网站，存在隐私泄露风险。

目标用户：注重隐私的 macOS 用户、摄影师、开发者、需要批量转换文件的普通用户。

证据：Every time I needed to convert a photo, a video, or a document, I'd end up on some sketchy website that either slaps ads everywhere, has a 50MB file limit, or - worst case - actually uploads my files to a server I do not control. For HEIC photos from my iPhone? Those are personal. I didn't want them leaving my machine.

变现：买断制付费下载（Mac App Store 或独立站），可提供免费试用/限量免费，Pro 解锁批量/CLI/高级格式；或订阅更新。

MVP：做一个 macOS 原生离线转换器，先支持 HEIC→JPG、PNG、PDF，视频 mp4/mov，音频 mp3，拖拽批处理与 Finder 右键；2 周内用 Swift + ffmpeg/ImageMagick 封装。

竞品：Handbrake、Permute、Preview、CloudConvert、ffmpeg、ImageMagick

摘要：作者因不满在线转换网站强制上传文件、广告和 50MB 限制，独立开发了 macOS 原生离线转换器 Convertessa，支持 1,100+ 格式、拖拽批量、CLI 和 Finder 集成。帖子展示明确隐私痛点，但没有付费意愿或收入数据，且已有 Handbrake、Permute 等竞品。
