Why use Video Compressor
Private and secure

Honest results
Choose quality and resolution. Progress comes from the encoder itself, and the result shows the exact size of your MP4 next to the original.
Free, no sign-up

How to use it
- Choose or drop your M4V file (up to 1 GB, 30 minutes), or import it from a link.
- Keep the High quality preset, or pick a lower resolution if you also want a smaller file.
- Select Convert to MP4 and keep the tab open while it uploads and converts.
- Preview the MP4 and download it.
M4V and MP4 are almost the same
M4V is Apple's variant of MP4. An unprotected M4V often plays after simply renaming it to .mp4. Converting is useful when an app or upload form still rejects it, or when it contains HEVC or AC-3 audio that the target device can't play.
Protected iTunes videos
Purchased or rented iTunes movies and episodes are encrypted with FairPlay. They are detected and reported as unsupported rather than converted.
Questions
Is M4V to MP4 conversion lossless?
No. The video is re-encoded to H.264, which is lossy, but converter pages start at the High quality preset, where the difference is hard to see at normal viewing size. The picture is never upscaled, and the shorter side is capped at 1080 pixels.
Should I just rename .m4v to .mp4?
Try that first for unprotected files. If the renamed file doesn't play or isn't accepted, convert it here to get standard H.264/AAC.
What happens to my file after conversion?
It's stored under a random ID on our server in Europe. The download link expires after 60 minutes and the file is then deleted automatically, normally within 75 minutes. Canceling deletes it immediately.
