Frequently Asked Questions

Why are screen recordings files so large?

Screen recordings are typically MOV or MP4 files at your display resolution (1080p, 1440p, or 4K). They often have high bitrates despite static content. This high quality is great for capture, but creates unnecessarily large files for sharing and storage. Compression can reduce size by 60-80% without noticeable quality loss.

Will compressing screen recordings reduce quality?

With smart compression settings, quality loss is minimal. Most viewers won't notice the difference, especially when viewing on phones or tablets. The key is choosing the right resolution and bitrate for your intended use.

What's the best format for screen recordings?

We recommend MP4 with H.264 codec. This provides excellent compression and works on virtually all devices.

Can I compress screen recordings on my phone?

Yes! This tool works in mobile browsers (Safari on iPhone, Chrome on Android). You can compress videos right on your phone without uploading them anywhere.

How much can I compress screen recordings?

Typically you can reduce file size by 60-80% with minimal visible quality loss. Downscaling to 1080p often provides the best balance.
