Before emailing about a failed M4A to MP4 conversion

Try a current desktop browser, close memory-heavy tabs, choose 720p, and test a short non-confidential sample. Helpful reports include the public page URL, source extension, file size, approximate duration, visual style, output settings, progress point, browser, operating system, and the complete error shown in the queue.

Do not email personal recordings, copyrighted media you cannot share, credentials, financial data, or another person's private content. Support can diagnose the converter but cannot retrieve a file that remained local to your browser.
