WinFF is free video converter for Win Xp to Win 10, Debian, and Ubuntu. WinFF has been used around the world to help people post their videos on the internet despite repressive regimes.

WinFF 1.5.5 is mostly just a cleaned up and repacked winff 1.5.4 for possibly the final version.

For now (and maybe ever), I am going to be hosting winff on my personal site.

This maybe the final version of WinFF except for preset updates. The WinFF website is being retired after 10 years. Thanks to Paul Gevers, Ian Stoffberg, and all other contributers for all you have done.



Debian 1.5.5 Stable 

Ubuntu 1.5.5

  1. Thanks for a wonderful product over the years still use it today

  2. This is a brilliant app. Thank you for the time and effort you put into creating it. Thank you even more for making it freely available. Still using it. Much appreciated.

  3. Thanks for this great software, and thanks for make it free (as in freedom). One of the best media converters for Windows :)

  4. is expired. would you check it in a bit?

  5. Hi, there's a bug in WinFF, where it doesn't support Unicode-named files in Windows (but works on Linux).

  6. Thanks Big Matt! This worked perfectly in a bare-bones Win7Pro VMware Workstation VM. I needed to convert a ~3 minute wmv to mp4. Btw, during rendering, I believe something is executing in %appdata% or %localappdata%. That caused problems in a later Win OS that had malware protection that monitors and prevents program or script execution in those locations. Hence my decision to try a bare bones Win7 VM, which worked without issue.
    Regards . . .

  8. Thanks Matt! For this awesome piece of evergreen software.

  9. Still use WinFF all the time at work, thank you!

  10. Hi Bigg Mac, glad to see WinFF is still going. I use the program all the time. Do hope you and your family made it thru Covid-19. Stay safe.

  11. Parabéns, só tenho a agradecer, mas, por favor, para ficar perfeito precisa consertar o BUG por não aceitar caracteres não usados no inglês, principalmente no nome do usuário do Windows, que não aceita renomear. O meu nome é "José" e o seu maravilhoso WinFF não aceita esse acento "é" utilizado nas línguas latinas como francês e português. Por sinal, português é a quarta língua mais falada do mundo. Milhões de pessoas vão agradecer! Obrigado.
