You can convert nearly any type of file. Video, Audio, Images, Documents, Ebooks and Archives are all supported. If a file cannot be converted, it is usually because the file is corrupted (like a video that you didn't finish downloading), DRM-protected (like a movie or ebook you purchased that has restrictions), or the conversion is logically impossible (like converting a document to a video).
The following output types are supported:
VIDEOS: 3GP, 3G2, FLV, MKV, MP4, MPEG-2, OGG, WEBM, or WMV.
AUDIO: MP3, OGG, WAV, WMA, AAC, FLAC, M4A, or MMF.
IMAGES: JPG, PNG, BMP, EPS, GIF, HDR, EXR, SVG, TGA, TIFF, WBMP, or WEBP.
DOCUMENTS: PDF, DOC, TXT, ODT, FLASH, or HTML.
EBOOKS: EPUB, MOBI, PDF, LRF, FB2, LIT, PDB, TCR.
ARCHIVES: ZIP, BZ2, 7Z, and GZ.
