AnyDownload

Download media from almost any site, entirely inside your browser.

AnyDownload is a browser extension powered by yt-dlp. It runs 100% locally: there is no companion app to install, no additional helper programs, and no server in the middle. Everything happens inside the extension on your machine. Features - Works on a huge range of sites: yt-dlp's extractors do the heavy lifting, so if yt-dlp can handle a site, AnyDownload can too. - Fully local: no companion apps, no backend servers, no relaying your URLs or files through a third party. - Format and quality picker: choose exactly which stream you want. - Convert to any output format: powered by Mediabunny, which is bundled with the extension and handles the muxing and conversion work you would normally use ffmpeg for. - Audio-only downloads: save just the audio track. - Logged-in downloads: uses the cookies from your existing browser sessions, so content you can access while signed in is content you can download. How it works AnyDownload runs yt-dlp inside the extension using Pyodide (CPython compiled to WebAssembly). Media processing (merging streams, remuxing, converting formats) is done by Mediabunny, also bundled in the extension. Nothing leaves your browser except the requests to the sites you are downloading from. Large files. WebAssembly is limited to 4 GB of memory. AnyDownload gets around this by using the Origin Private File System (OPFS) for storage instead of holding everything in memory. Limitations - No DRM-protected content. AnyDownload cannot download media protected by DRM. Disclaimer Only download content you have the right to save. You are responsible for complying with the terms of service of the sites you use and with the laws that apply to you.
