Local video audio tools
Turn a browser-readable video into MP3, WAV, or OGG, inspect basic video metadata, and keep the original file on your device.
This free online tool allows you to extract audio tracks from video files (such as MP4, MOV, or WebM) directly in your browser. All processing happens locally on your device without uploading any data to external servers, ensuring complete privacy. No sign-up or software installation is required.
A clear local workflow
This toolkit performs format conversion and browser-readable metadata inspection only. It makes no quality, copyright, compatibility, or rights decision for you.
Select a browser-readable video from your device. Nothing is sent to a Rigid Apps server.
Pick MP3 for compatibility, WAV for uncompressed audio, or OGG for an open compressed option.
Open the download or review the source in a trusted player. Keep the original until you confirm the result is suitable.
This toolkit is designed for creators, students, and professionals who need fast, secure media processing.
How we safely process your files without a backend server.
WebAssembly (Wasm) Engine: Instead of sending your file over the internet, we load an optimized media processing engine directly into your browser's memory using WebAssembly. This brings desktop-grade computing power to your web tab.
In-Memory Decoding: When you select a file, the browser reads it locally. The video is decoded into raw frames or audio samples in real time, utilizing your device's CPU and RAM.
The tool loads its processing code in your browser and handles selected media in the active tab. It does not create a Rigid Apps account, upload queue, or cloud library for your content.
A successful download only means the browser produced a file. Check timing, playback, file size, and your rights to use the media before publishing, deleting an original, or using it in a project.

Questions and answers
No. The selected file is read and processed in the active browser tab. Rigid Apps does not receive the source video, extracted audio, or generated output.
The tool reads the first audio track that the browser encoder can access and writes a new MP3, WAV, or OGG download. The original file is not changed.
MP3 is broadly compatible and useful for sharing. WAV is uncompressed and can be larger. OGG is an open compressed format supported by many modern players. Test the output in the player where you intend to use it.
For MP3 and OGG, bitrate is the amount of data allocated per second of audio. A higher number can create a larger file and may preserve more detail, but the source track sets the upper limit of what can be retained.
The first job loads the browser encoder, then the browser must decode and write the media locally. Runtime, resolution, source codec, device speed, and available memory all affect the time.
No. A video without an audio track cannot produce meaningful extracted audio. The tool will report a processing error rather than inventing or generating sound.
Choose a video your current browser can read, such as common MP4, MOV, M4V, or WebM files. Support depends on the browser and the codecs inside the file, not only its extension.
Local Encoding & Blob Generation: The raw audio is then re-encoded into your chosen format (MP3, WAV, or OGG). The final output is packaged as a Blob URL, triggering a native download prompt from your browser that writes the file back to your hard drive.
Local browser processing temporarily needs memory for the source, decoded media, and output. The limit adapts to reported device memory to reduce crashes, though a lower limit may apply on less capable devices.
It shows descriptive values supplied by the browser, including filename, file size, MIME type when available, duration, and dimensions. It is not a quality assessment or forensic inspection.
Fast stream-copy trimming can start near a video keyframe. Check the downloaded clip before publishing if the exact first frame or timing matters.
Only if you have the required rights or permission for the source recording, video, music, and other included material. The tool provides a technical conversion and does not grant usage rights.
No. This is a deterministic conversion tool, not an enhancement, transcription, noise-removal, or AI audio-generation service.
Yes. The tool runs in any modern mobile browser. However, processing speed will depend on your phone's processor and available memory. Keep the browser tab active during extraction.
No. When converting to WAV, the output is uncompressed and retains the exact fidelity of the decoded source. When converting to MP3 or OGG, some compression occurs, but standard high bitrates are used to maintain excellent listening quality.
There is no hardcoded duration limit, but very long videos (over an hour) may exhaust your browser's available memory before finishing. For massive files, we recommend processing them on a desktop computer rather than a mobile device.
