### 1/5 — Would not process MKV

*2026-05-11, version 1.5*

Doesn’t import video for processing

### 3/5 — Started out well, increasingly buggy

*2023-02-21, version 1.5*

I quite like this app for converting my MKVs to MP4 but over time it has started to bug out and just not load files in. I hope it gets fixed soon.

### 5/5 — Easy to use and fast

*2022-12-23, version 1.5*

This App does exactly what it promises to do, converting MKV to MP4 very fast, the price for the pro version is absolutely appropriate / reasonable.

The only thing missing for me is an option to choose the preferred quality of the audio conversion from dts to ac3 or ac3 to aac.

### 5/5 — Remuxing and transcoding made simple

*2020-11-02, version 1.1*

This is the easiest way of creating iOS-compatible mp4 files from sources like mkv and webm. Well-designed and reliable app!
