Compress MP4 Videos
Reduce your MP4 video file sizes by up to 70% without noticeable quality loss. Perfect for sharing on social media, email attachments, and freeing up storage space.
Why Compress MP4 Videos
Video files are among the largest files on your device. A single minute of 1080p MP4 footage can exceed 100MB, making videos difficult to share via email, upload to social platforms, or store efficiently.
Our MP4 compressor uses H.264 encoding with optimized CRF (Constant Rate Factor) settings to reduce file size dramatically while keeping visual and audio quality high. The compression targets redundant frame data that the human eye doesn't notice.
Whether you're a content creator preparing videos for upload, a business professional sharing presentations, or simply trying to free up phone storage, MP4 compression makes your videos more portable without sacrificing watchability.

Frequently Asked Questions
Will video quality be noticeably worse after compression? ▼
With the Medium and High quality settings, the difference is virtually imperceptible for most content. Low quality compression may show some softening in fast-motion scenes, but remains excellent for casual sharing.
Does MP4 compression remove the audio track? ▼
No. Our compressor preserves the audio track and re-encodes it with AAC for optimal quality at reduced file size. Both video and audio channels are maintained.
How long does video compression take? ▼
Processing time depends on video length and resolution. Most videos under 5 minutes are compressed within 30-60 seconds. Longer or higher-resolution videos may take a few minutes.
What's the maximum MP4 file size I can compress? ▼
You can compress MP4 files up to 50MB each. This accommodates most video clips suitable for web sharing and social media.
Does compression change the video resolution? ▼
No. The video resolution (e.g., 1080p, 720p) remains exactly the same. Compression reduces file size by optimizing encoding efficiency, not by shrinking the frame dimensions.
