Video compression questions.
What is Video Compressor - reduce?
It is an iPhone and iPad app for making smaller video files. It is useful when a clip is too large to share or when you want a smaller copy to keep, with presets and size comparisons before saving.
Does compressing a video reduce its quality?
It can. The result depends on the original video and compression settings. Compare motion, faces, text, and dark areas in the exported copy. Use a higher-quality preset if important detail is lost.
Will every video shrink by the same amount?
No. Duration, source encoding, motion, and the chosen preset affect the result. Already-compressed videos may offer less room for further size reduction.
Which devices are supported?
Video Compressor - reduce supports iPhone with iOS 17 or later and iPad with iPadOS 17 or later. Dynamic Island progress requires a compatible iPhone. Check the App Store for current compatibility and availability.
