  • Built-in High Quality Engine guarantees high-quality output.
  • 3 ways to shrink M4V file size: convert M4V codec/format; lower resolution/bit rate/frame rate; trim/crop M4V.
  • Convert & compress M4V to MP4, HEVC, WebM, 3GP, FLV, WMV , etc. accepted by non-Apple Android devices, players.

Part 1. How to Compress M4V Videos without File Size and Quantity Limits

It's very easy to shrink M4V with this tool, thanks to well-designed user interface. And unlike free online video compressors, this solid M4V compressor allows you to import M4V video without file size, video length and quantity limits, nor annoying premium service upgrade pop-up. Load M4V over 500MB, 1GB or 10GB from your laptop. Then start to reduce M4V video footage:

Step 1: Run the high quality free video compressor for Mac or Windows on your computer. Click Add Video icon in the top-left corner and select M4V video files to shrink. The tool supports to shrink M4V files in batch.

Step 2: Choose output format. MP4 HEVC is recommended first.

Converting M4V (H264/MPEG-4) to MP4 (HEVC x265) is the most efficient way to downsize M4V footage size since HEVC x265 codec has much higher compression efficiency than M4V common codecs H264 or MPEG-4, roughly 56% smaller in 720p, 62% smaller in 1080p and 64% bit rate reduction in 4K 2160p.

Certainly, you can also convert and compress M4V to WMV, FLV, WebM, 3GP, etc. other formats with much smaller-sized output file. Or extract audio from M4V video and saved as MP3, AAC, AC3, FLAC, OGG, WMA, etc. individual audio file to make M4V video smaller in size. It offers you with 420+ pre-programmed profiles to choose from.

Parameter adjustment will further downsize M4V video size around 30-60% bit rate reduction. Please keep in mind that don't overdo the parameter lowering, which would cause video quality degradation.
