Tapirconvert

Hey! I build SEO-driven tools solo, and video conversion is one of those searches with real volume in every market — but almost zero fixed cost to serve, since ffmpeg.wasm runs everything in the visitor's own browser instead of my server. That math made it worth building. I actually made the first version for myself, then decided to clean it up and put it out publicly. Since then I've kept adding to it: it's now in 8 languages (EN, ES, PT-BR, JA, RU, TR, ID, ZH-TW), and for the AI upscaler I ended up training and exporting my own ESPCN/FSRCNN super-resolution models to ONNX, so a 4K upscale runs client-side too — no GPU server involved. It's free with no signup, no watermark, no file size cap, monetized through ads instead of a paid tier, with basically zero marginal cost per conversion, gating it behind a paywall never made sense to me. Would love feedback: which conversion or compression use case is missing for you? And does the browser-only AI upscaler feel fast enough on your machine, or does it choke on larger files?

Client-side WebAssembly conversion with no upload is the right call for anything privacy-sensitive, and it should make small files basically instant since there's no round trip. Does the AI 4K upscale step also run fully in-browser, or does that one need a server?

Super practical video toolkit, with AI upscaling, format conversion and compression, all processed locally on your device with zero uploads, no watermarks and no limits.

Tapirconvert Your product has strong potential, but I found a few key improvements that could make it even better. I'd love to share my feedback and suggestions—please contact me at [email protected].

Clean, fast, and privacy-focused! Having a free WebAssembly-based converter with no watermarks or daily limits is super handy. Great launch!
