Frequently asked questions
How do I convert M4V to MP4?+
Upload your M4V file (or drag it onto the box above), wait a few seconds while StandardsPDF converts it in your browser, then download the MP4. There is nothing to install and no account required.
Is converting M4V to MP4 free?+
Yes. M4V to MP4 conversion is free on the StandardsPDF free tier – no watermark, no signup, and no credit card. A Pro tier lifts the file-size and daily limits if you need more.
Will the MP4 keep the quality of my M4V?+
StandardsPDF aims for the highest fidelity the MP4 format allows, so your video comes through looking as close to the original as possible. Some format-specific details may adapt where MP4 works differently to M4V.
Will the audio from my M4V stay in sync in the MP4?+
Yes – when converting M4V to MP4 the audio track is muxed back with the video so playback stays perfectly in sync.
