preferably free, either a program or online conversion

I've use this website before http://media-convert.com/. Its pretty quick and the video quality seems good.
For Windows I always used Super ©. According to eRightSoft's website it supports the following input sources:
- Input Image Sequence: jpg, pgm, png, ppm (with sequentially numbered-ONLY filenames) having the same filename numbered-ONLY format. Example: 0001.jpg --up to--> 0999.jpg note that this format will NOT work name_0001.jpg --up to--> name_0999.jpg (take out name_)
- Input Video format: 3gp, 3g2, amv, asf, avi, dat, dvr-ms, fli, flc, flv, m2ts, mpg, mkv, mov m4v, mp4, nsv, ogm, qt, rm(vb), str, swf, ts, trp, ty, ty+, tmf, viv, vob, wmv ..
- Input Audio format: aac, ac3, amr, flac, mmf, m4a, mp2, mp3, mpc, ogg, ra, wav, wma ..
- Input AviSynth Script Files: avs. To write a script and specify advanced encoding commands using AviSynth scripts!
For Mac OS X I use Handbrake
Both applications are free to use.
As Nuno Curado suggestioned, use SUPER. I think is the best. But you must have the lastest codecs in your computer to be able to convert to some filetypes. Then download K-Lite Mega Codec Pack.
