This page turns your audio files into something that sounds like it came out of a phone call. Upload an audio file, click the green button below, wait a few seconds, download, and then enjoy the soothing sounds of low quality audio! Also check out the audio and image combiner tool! The audio you create here is perfect for that tool!
BitMash is a free, browser-based media tool that transforms clean, high-quality audio and image files into intentionally low-fidelity, retro-styled versions. Powered by WebAssembly and FFmpeg, every conversion runs locally in your browser. This means no uploads to any servers, and no data ever leaves your device. Originally built to recreate the quirky, compressed audio effects found in old music videos and meme videos, BitMash has grown into a playful toolkit for reducing audio quality, pixelating images, and even combining them into offbeat video creations. It’s a simple, fun way to mangle your media in seconds.

While we currently focus on web-based applications, we are excited to expand into new platforms and technologies in the future.
