4k video converter

A 4K video converter is an online or offline tool that helps you convert 4K videos into other formats, resolutions, sizes, and vice versa. Nowadays, 4K content is all around us, especially now that devices like iPhones can shoot 4K 30/60FPS, GoPro and DJI capturing 4K UHD videos, Cinema 4K, 4K 4:3, Canon 4K 10bit HDR (up to 60/120FPS), besides streaming 4K content on various platforms like YouTube. The popularity of 4K stems from its crisper and HD video quality over other formats.

However, things get complicated when you need to export 4K videos from iPhone to TV/computers, playback on Windows/Mac, or edit in apps like DaVinci Resolve, iMovie, Premiere, and more. As such, the need for a 4K video converter is inevitable for a smooth sail when playing or editing 4K videos. In this article, we will present you the best 4K video converters on Windows, Mac, web, and Android smartphones.

4K Video Converter: Why You Need It?

  • Compatibility issues – Some 4K video formats may not be playable or editable and thus require conversion to other formats.
  • Downscaling 4K videos – Turn down the video resolution without losing quality to facilitate quick sharing and saving storage space. For instance, 4K to 1080P.
  • Upscaling low-res videos to 4K – For a streamlined 4K video editing process and revitalizing low-resolution videos. For instance, 1080P to 4K.
  • Addressing laggy/stuttery 4K clips – Some devices fall short when you need to play and edit 4K HEVC footage smoothly.
  • Resource hungry – 4K videos are CPU intensive (both in playback and editing) and result in choppy performance on underpowered devices.
