ALLConverter to iPhone Portable

Made as the portable counterpart of ALLConverter to iPhone, this is a straightforward piece of software designed go help you quickly prepare video files and subtitles for playback on iPhone devices.
It offers support for several audio and video formats, such as .mkv, .asf, .divx, .xvid, .flv and .mp3, along with .smi, .srt, .sub, .txt and .mpl2 subtitles.

Portability perks

Since there is no setup pack involved, you can drop the executable file in any part of the hard disk and just click it to launch the app.
Another option is to keep it stored on a USB flash drive to be able to swiftly convert videos from any computer you access. It doesn't modify Windows registry settings.

Intuitive interface and options

The interface is based on a window that resembles the display of iPhone 4, which lets you select the audio, video and subtitle files you want to mux and convert.
It's possible to preview clips in an embedded media player, pause and stop the stream, as well as check out the current play position and total time. Plus, you can select the quality between low and high, and proceed with the conversion operation with one click.
Apart from the fact that you can pause the task to temporarily allocate system resources to other applications, there are no other notable options provided by this piece of software.

Downsides and conclusion

Unfortunately, ALLConverter to iPhone doesn't provide batch processing support, audio, video and subtitle customization, nor the possibility to modify the destination directory.
In fact, it failed in several attempts during our tests to convert clips, although it didn't indicate any errors. We must also take into account that it hasn't been updated for a long time. Perhaps you should look for a more reliable video converter for iPhone devices.
