Terms for the free M4A to MP4 converter online

Terms for using the free M4A to MP4 converter online

By using M4AtoMP4, you agree to these terms. If you do not agree, do not use the converter. The service is a browser-based media utility provided without an account and may be changed, limited, or discontinued.

You are responsible for checking whether an output meets the technical, legal, accessibility, and quality requirements of its destination. A successful download only confirms that the local conversion engine created a file; it does not guarantee acceptance by another service.

Your rights and responsibilities for converted media

Only process media that you own or are authorized to use. You remain responsible for copyright, privacy, publicity, contractual, confidentiality, and other rights connected with source files, cover images, audio, and finished outputs.

The converter does not grant rights to music, recordings, artwork, voices, trademarks, or other content. Local processing does not make an otherwise unauthorized use lawful.

• Do not use the site to infringe intellectual-property rights
• Do not attempt to bypass DRM or access controls
• Do not use the service to distribute malware or abusive content
• Do not interfere with the site, hosting layer, or other users

M4A and MP4 output quality limitations

Media conversion can change quality, metadata, timing, channel layout, bitrate, and compatibility. Unsupported codecs, corrupt data, unusual timestamps, very large files, or limited device memory can produce an error or incomplete result.

You should listen to or watch the entire finished file before deleting the source. Keep an independent backup of important media. M4AtoMP4 is not an archive, cloud storage service, recovery service, or professional mastering tool.

Availability of the browser-based audio converter

The site is provided on an as-is and as-available basis to the maximum extent permitted by applicable law. Browser updates, device limitations, hosting interruptions, WebAssembly restrictions, and third-party network controls can affect availability.

To the maximum extent permitted by law, M4AtoMP4 is not liable for lost media, lost profits, publication failures, missed deadlines, incompatible output, or indirect and consequential loss arising from use of the site. Some jurisdictions do not allow every limitation, so mandatory local rights still apply.

Changes to these M4A converter terms

These terms may be revised when the converter, supported formats, ownership, or legal requirements change. The update date identifies the current published version. Continued use after a revision means the new terms apply from that point forward.

Questions about these terms can be sent to legal@m4atomp4.com. Do not attach private or copyrighted media to a general legal inquiry unless a secure transfer method has been agreed first.
