What Are File Converters?
File converters are tools that transform a file from one format into another - like turning a PNG into a WebP, or pulling the audio out of an MP4 and saving it as an MP3. All conversions here run 100% in your browser using the Canvas and WebAssembly APIs - no data uploaded, completely free, unlimited, and no signup required.
Whether you're optimizing images for a faster website or pulling a podcast's audio out of a video file, good file converters save you from installing bulky desktop software or trusting a random upload site with your files.
