Compress a Screen Recording

Screen recordings are surprisingly huge because they capture at high frame rates and bitrates. This tool re-encodes them to a fraction of the size on your own device — ideal for sharing demos and bug reports.

Why screen recordings are so large

Tools like QuickTime, OBS and built-in phone recorders save at high bitrates and often 60fps, so a few minutes can be hundreds of MB. Re-encoding at a sensible bitrate (and 30fps if you don't need 60) cuts size dramatically while text stays readable.

Frequently asked questions

Why is my screen recording so big?
High capture bitrate plus 60fps. Most demos and walkthroughs look fine at 30fps and a lower bitrate, which can shrink the file by 80% or more.
Will the text in my recording stay readable?
Yes, as long as you keep the resolution. Compression mainly affects fine motion detail; static text and UI remain crisp.
