Local-First Engineering Manifesto

Eliminating the Cloud Middleman for Audio & Video

MediaConvert was engineered with a radical proposition: your proprietary media files, confidential voice notes, and high-bitrate video footage should never touch a third-party cloud server.

The Flaw in Traditional Online Converters

For twenty years, online file converters forced users into a dangerous bargain: upload your private files across public internet cables to remote cloud servers, wait in long queue lines, and hope the server administrator deletes your footage afterward.

For investigative journalists, medical professionals dictating patient charts, corporate legal teams under non-disclosure agreements, and independent musicians with unreleased stems, this legacy architecture is an unacceptable security vulnerability.

The Modern Browser As A Digital Audio Workstation

With the advent of the Web Audio API, HTML5 Canvas MediaStreams, and WebAssembly (WASM), personal laptops and smartphones now possess dedicated hardware video decoders and multi-core signal processors.

MediaConvert executes all transforms in your browser’s volatile RAM. When you close the tab, every intermediate buffer is instantly erased. Zero logs, zero analytics on your audio, zero server costs passed to you.

Our Core Engineering Principles

The strict technical constraints that govern every line of code we ship.

1. Absolute Zero-Egress

We never instantiate upload endpoints for user media files. Inspect your browser’s Network DevTools tab at any time: no POST requests transmitting binary media are ever initiated.

2. Pure Local Hardware Speed

Why choke your workflow with home Wi-Fi upload speeds? We tap directly into your local NVMe or SSD bus, reading gigabytes of PCM data instantaneously.

3. Mathematical Precision

From 64-bit floating point waveform decoders to bit-accurate 16-bit RIFF WAV serializations, we adhere strictly to AES, ITU-R BS.1770, and EBU R128 audio standards.
