How Free Video Compression Software Reduces File Size on Mac
Free video compression software for Mac, such as Macxvideo AI, HandBrake, QuickTime Player, and iMovie, use a combination of techniques to shrink video files while keeping quality acceptable. Here are the most common methods you can use:
1. Lowering Bitrate
Reducing the bitrate controls how much data is used per second of video. Free software lets you adjust the bitrate to balance file size and quality. For example, lowering bitrate by 20–50% can significantly reduce size without noticeable quality loss.
2. Reducing Resolution
Downscaling your video from 4K to 1080p, or 1080p to 720p, is an effective way to shrink the file. Free tools like QuickTime or HandBrake allow you to choose export resolutions for different use cases, such as WhatsApp or email.
3. Choosing Efficient Codecs
Modern codecs like H.265 (HEVC) and VP9 provide higher compression efficiency than older codecs like H.264. Free software like HandBrake supports these codecs for smaller files with minimal quality loss.
4. Trimming and Cropping
Removing unnecessary parts of a video or cropping black bars reduces file size. Tools like iMovie or HandBrake allow you to trim or crop videos easily before compression.
5. Removing Extra Data
Free Mac software can remove extra audio tracks, subtitles, or metadata that are not needed. This helps reduce file size without affecting the main video quality.
By combining these techniques, you can compress videos on Mac efficiently using free tools, whether you’re sharing via email, WhatsApp, or just saving storage space.
