Combine an FFmpeg powered back-end with VLC rendered previews, then add in file size estimation, a gorgeous user interface and make it entirely free. That is Adapter - the ultimate converter app for Mac and PC.
Adapter integrates two VLC players side-by-side giving you the power to preview any video, audio or image conversions and compare the output to the original. Additionally, Adapter estimates the file size of your conversion output so you know what you'll get before you begin the conversion.
Adapter makes batch conversion of a breeze. Simply drop a group of images, songs, or movies into the queue, select your output settings, hit convert - done. Use image batch conversion to set multiple images to the same height, convert TIFFs to JPGs, add watermarks and more. Easily compress groups of WAV files to MP3 or transcode your movie collection to work on your iPhone, Android or other device.
Adapter lets you easily trim the duration of any audio or video files and easily export it to the format of your choosing. You can use this feature to make high quality animated GIFs or convert songs to custom ringtones for an iPhone, Android or other device.
Adapter adapts to the complexity that you need. Most conversions can be preformed simply by dropping files into the queue and selecting the output mode from a pop-up button. If you need more control, advanced panels can be toggled.
Adapter is freeware (100% free software). Unlike other free apps, Adapter is lightweight and comes with a completely spam free installer that doesn’t install toolbars or gunk up your computer. Adapter won’t add obnoxious watermarks to your output. There are no limits or restrictions on Adapter. Please enjoy and please spread the word!
