Audio to Video: A Client-Side Web App
I recently ran into a need to convert an .mp3 file into a video format so I could upload it to a platform. To solve this, I built Audio to Video, a client-side web app that performs this conversion entirely within your browser. This blog post provides a quick overview of how it works.
The Goal
The goal was to create a tool that respects user privacy, is accessible, and offers good performance. It shouldn't require any server-side processing or additional software installations. Everything happens right in your browser.
The Tech
ffmpeg-wasm: This WebAssembly port of FFmpeg handles the core video processing tasks. It allows for audio and video manipulation directly within the browser environment. The resulting video is displayed for preview and can be downloaded using a convenient button. Service Workers enable the app to function even offline.
