Desktop Converter VS. Online Converter

Let's take a deep rundown at two variants so that you can easily take your pick amongst both of them:

Safety – Desktop apps have a greater level of safety than online ones which are more likely to get malware threats.

Download & Conversion – Desktop converters always come with both downloading and transcoding features compared to online counterparts. More so, desktop apps do pack with more video/audio coding formats.

Conversion Speed – Thanks for the support of hardware acceleration, desktop converters are speedier when transcoding one format to another.

File Size Limits – Online video converters usually have an upper limit on file size uploads.

Convenience – When using online converters, you don't have to download extra apps on your computer as long as you have a robust internet.
