9xconvert
Convert and edit video, audio, images, GIFs, subtitles, and documents locally.
9xconvert converts and edits files on your own machine — video, audio, images, GIFs, subtitles, PDFs and the other document formats. Nothing is uploaded, which is why there is no server file-size limit or upload wait. Once the account is verified, local file conversion works without a connection.

9xconvert uses available CPU and GPU capabilities where supported. Actual speed depends on your device, input format, output codec, resolution, filters, and selected settings; not every operation is GPU-accelerated.
