KaruMovie

Make your video fit a 25 MB, 100 MB or custom file-size limit.

KaruMovie makes video compression simple: choose one video and set a size limit. No bitrate, resolution or frame-rate settings to work through.

• Choose from 10 / 25 / 50 / 100 MB presets, or set a custom limit from 1 to 1000 MB in 1 MB increments. • Select a video from Photos or Files. • Preview the original and play the compressed result. • Check the resulting file size and percentage saved. • Save to Photos or export with the iOS share sheet, including AirDrop and Files. • Use videos already within the limit unchanged, including MOV and HEVC files. • Keep HDR when compressing supported HLG / Dolby Vision 8.4 videos. • Preserve multiple audio tracks.

Everything is processed on your device. Videos are never uploaded to a developer server. No account, ads or behavioral tracking. Your original is never deleted or overwritten.

When compression is needed, standard video is encoded as MP4 / H.264 / AAC; supported HDR video uses HEVC / MOV. Unsupported HDR formats are reported rather than forcibly converted. Some videos may require a larger size limit; the app tells you if it cannot meet your target.

1 MB = 1,000,000 bytes.
