Open toolFrequently asked questions
Yes - every tool listed here is free to use, with no signup, no account, no trial period and no usage limits. They are part of CODECS.COM, a multimedia software resource that has been online since 2004.
No. All tools run directly in your web browser. There is nothing to download or install. As long as you have a modern browser - Chrome, Firefox, Edge, Safari or Opera - you can open any tool and start using it immediately.
For most tools, no. The Audio Extractor, Audio Converter, APK Checker, Codec Finder, GPU Checker and M3U Link Generator all process your files entirely inside your browser using JavaScript and WebAssembly - nothing is sent to our servers. The Stream Extractor uses a small server-side helper to bypass CORS, but it does not store any data.
Any modern browser works. Chrome and Edge generally have the widest codec support for the GPU Checker and FFmpeg.wasm tools. Safari on iOS works for most tools but has stricter limits on file size for in-browser processing. Firefox handles all tools well.
Yes - every tool is responsive and works on mobile browsers. For heavy in-browser processing like audio conversion or codec analysis on large files, a desktop browser will be noticeably faster, but the smaller utility tools (M3U Checker, Codec Troubleshooter, IPTV Finder) work perfectly on mobile.
No. None of these tools store your data. The M3U Link Generator encodes the entire playlist into the share URL itself - we never see it. File-processing tools work locally in your browser and never upload your files. Once you close the tab, nothing remains.
Yes - please use the feedback form on CODECS.COM or email us. Every tool here started as a suggestion or a need we ran into ourselves. New tools and improvements are added regularly based on user feedback.
Some of the underlying libraries are open-source - FFmpeg.wasm, MediaInfo.js, hls.js, JSZip and others - but the tools themselves are bespoke to CODECS.COM. Where we use a public dataset (such as iptv-org for the IPTV Channel Finder, or Radio Browser for the M3U Finder), we credit the source.
