About

I'm Felix, an indie developer from Shenzhen. After 5+ years as a software engineer, I went indie to build useful products for a global audience, from passport photo tools and music games to AI-friendly developer workflows. I care about simple products, fast shipping, SEO, and using AI as a real building partner. I also write about AI development, indie hacking, and the inner work behind creating things.

Passport Size Photo - Create compliant passport photos from home

Passport Size Photo helps you create compliant passport, visa, and ID photos online without visiting a studio. Upload a clear picture, choose the right country preset, check the crop and background, then download either a digital file for online forms or a 4x6 print sheet for home or pharmacy printing. Unlike generic photo editors, it is built around official document-photo constraints: exact dimensions, 300 DPI output, country-specific presets, and practical preview guidance before export.
