Post Description

Most online converters upload your files to their servers, enforce size limits, and require accounts. LocalConvert fixes that by running ffmpeg entirely in the browser via WebAssembly.

Your file never leaves your device. No account, no size limits, no waiting for uploads.

Live app: https://local-converter-6q1j.vercel.app GitHub: https://github.com/Gokul-Raj-R-Coder/local-converter

Built with Svelte + TypeScript + ffmpeg.wasm. Would love feedback on edge cases or unsupported formats.
