Copyright Policy | MP4ToMP3.tools
Responsibilities and contact information for copyright questions.
Last updated 2026-09-04
Use MP4ToMP3.tools only with media you own or are otherwise authorized to process. Changing a container or audio format does not remove copyright or license obligations.
Browser-local processing
The converter processes selected media in your browser and does not intentionally upload or host the source or converted result. We therefore do not maintain a public catalog of user media or cloud download links that can be removed from the service.
Copyright questions
For a copyright concern involving content published by MP4ToMP3.tools itself, email support@mp4tomp3.tools with the relevant public URL, a clear description of the work and a way to contact you. Do not attach the disputed media unless requested through an appropriate channel.
This page does not name a statutory agent, physical office or legal process that has not been established. It is a product-policy draft, not legal advice.
Open-source software
The browser converter uses a versioned FFmpeg.wasm runtime. Read its license and third-party notices and the matching Corresponding Source instructions. The matching SPDX SBOM identifies the exact runtime files and upstream source revisions.
The complete source-only Corresponding Source archive for this FFmpeg runtime has been published and independently retrieved and verified. The archive contains 20 source archives, zero npm package tarballs and zero compiled runtime files.

The archive is linked from this page; it is not downloaded when this page loads. Publication and engineering verification are not professional GPL, codec, patent or binary-distribution legal approval. Production remains blocked pending that approval and RR-002 staging/CDN retention, cache and rollback verification.
