The assistant opens with your file and converts it on your own device; the file itself is never uploaded. When the MP4 file is ready, click Save. Prefer to set everything by hand, or batch-convert several files into a ZIP? The classic converter is one click away on this page.
M4V is Apple's MP4 variant used by iTunes and older iOS exports. Many Android phones, smart TVs and Windows apps reject the .m4v extension even though the contents are nearly identical to MP4. Converting M4V to MP4 fixes that with no visible quality change.
The converter re-encodes the H.264 video and AAC audio into a standard MP4 container, keeping the source settings by default. Note that DRM-protected iTunes purchases cannot be converted by any tool; only unprotected M4V files will open.
M4V (iTunes Video): M4V is Apple's flavour of the MP4 container, used by iTunes and older Apple devices. Unprotected M4V files are structurally almost identical to MP4. It is best for iTunes libraries and older Apple devices.
MP4 (MPEG-4 Part 14): MP4 is the most widely supported video container in the world. It usually carries H.264 or H.265 video with AAC audio, plays on every phone, browser, TV and editing app, and is the safest choice for sharing. It is best for sharing, social media, web playback and mobile devices.
In short: keep M4V when the priority is iTunes libraries and older Apple devices, and switch to MP4 when the file is headed for sharing, social media, web playback and mobile devices. Need a different target? The full Video Converter supports every format listed below.
Nearly. M4V is Apple's MP4 container with optional DRM and AC3 audio. Unprotected M4V converts to a standard MP4; the video is re-encoded with the source settings kept, so it looks the same.
No. iTunes purchases are protected with FairPlay DRM and cannot be converted. Home recordings and unprotected exports convert fine.
Yes. Converting M4V to MP4 on Convertor.video is free, with no watermark and no sign-up. The AI assistant runs on a free daily allowance of assistant credits; the classic converter on this page has no daily limit at all.
No. The conversion runs inside your browser using WebCodecs and FFmpeg compiled to WebAssembly, so your .m4v file is read and converted on your own device and never uploaded, which keeps private recordings private and means there is no waiting in an upload queue. The AI assistant only sees what you type and basic facts about the file: its name, format, duration and size.
There is no plan or account limit, but the converter loads the whole M4V file into your browser's memory, so about 2 GB per file is the practical ceiling; larger files may fail to open. Long or high-resolution files also take longer, especially on phones.
Yes. Ask the AI assistant for a resolution, frame rate or bitrate in your request. Audio and subtitle track selection, the codec list and every other setting are in the classic converter, one click away on this page.
The video is re-encoded into MP4. Keep the source codec, resolution and bitrate (the defaults) and an ordinary 8-bit video is visually the same as your M4V, while a 10-bit, HDR or full-color (4:2:2 or 4:4:4) source can lose some color detail. Lowering the bitrate or resolution is what reduces quality, and you control that trade-off by asking for it (or in the classic converter's settings).
It is built and tested on current desktop Chrome and Edge, which are also fastest because they expose hardware-accelerated WebCodecs video decoders. Recent Firefox and Safari releases support the same web APIs; if a file fails there, try Chrome or Edge.
