Practical Video Compression Tips
Regardless of which tool you choose, these tips will help you achieve better compression results:
- Choose H.265 (HEVC) Encoding: It offers roughly 50% better compression than traditional H.264 at the same visual quality, resulting in significantly smaller files.
- Lower Resolution to Match Actual Needs: If the video will only be viewed on a phone, 1080p is usually more than sufficient — there's no need to keep it at 4K.
- Adjust Frame Rate: Dropping from 60fps to 30fps can dramatically reduce file size, and most viewers won't notice the difference for standard content.
- Trim Unnecessary Footage First: Cut out any unnecessary intro or outro segments before compressing. Less content means a smaller starting point and better results.
- Compress in Stages if Needed: For extremely large files, consider a rough trim first, then apply compression for a more manageable workflow.

Based on different use cases, here are our recommendations:
- Occasional Compression, Maximum Convenience: Go with Clideo or 123APPS — open the webpage, drag and drop, done.
- Larger File Sizes: FreeConvert's generous 1GB free limit makes it the best choice for bigger videos.
