Compressor is the fastest video compressor for Android. Period. Full stop. End of discussion.
Compared to the top Play Store result for video compressor, Compressor is 117x faster (11 seconds vs 21 minutes).
It's completely native, ad-free, no paywalls, no subscriptions, just an awesome free app, written completely in Kotlin and using native Media3 transformer pipelines for compression.
It's got everything you'd want from a video compressor, presets, target size, etc, without any extra bloat.
