pixtidy - a passport and visa photo checker that runs entirely in your browser (and what I learned checking 21 governments' rules)

Why I built it: a passport photo at a US pharmacy or Post Office costs about $15 to $17 (Walgreens lists $16.99, USPS $15), and I wanted a way to check a phone photo against the official rules for free before paying anyone, without uploading my face to a server. I use MediaPipe face landmarks and segmentation. The photo never leaves the browser.

痛点：美国药房或邮局拍护照/签证照片要花15–17美元，用户希望先免费用手机自拍检查是否符合官方规则，又不想把脸传到服务器上。

目标用户：需要办理护照/签证的旅行者，尤其是美国及其他被覆盖国家/地区的申请人；潜在B端是旅行社和签证代办。

证据：a passport photo at a US pharmacy or Post Office costs about $15 to $17 (Walgreens lists $16.99, USPS $15), and I wanted a way to check a phone photo against the official rules for free before paying anyone, without uploading my face to a server. ... Checking is free; the file costs US $9.99 once, with a full refund if an official rejects a photo it passed. ... Revenue is $0 so far.

变现：免费检查 + 一次性 $9.99 导出合规照片（含官方拒收全额退款承诺）；后续可加多国批量包、加急/人工复核、面向旅行社和签证代办的B2B API。

MVP：用 MediaPipe 在浏览器端做人脸关键点与分割，检查背景、光线、清晰度、表情、尺寸并裁剪压缩 JPEG，先覆盖3–5个高频文件（美国护照、美国签证、申根、英国、印度），免费检查+$9.99下载，附退款保证。

竞品：PhotoAiD、Passport-Photo.Online、iVisa photo service、IDPhoto4You、Walgreens/USPS 等线下拍照点
