Překresleno.cz: Convert images without uploads (WebAssembly-powered)
If you have ever used an "online image converter", you have probably had the same two concerns: privacy and speed. Do I really want to upload personal photos somewhere? And why does a simple conversion take so long?
I built Překresleno.cz to remove that tradeoff. It is a modern image converter that runs entirely in the browser: drop in images, choose an output format, adjust a few practical settings, and download the result individually or as a ZIP. No uploads. No accounts. No server-side image processing.
