Download Video TikTok MP4 does not always support all video resolutions, as it mainly depends on the original quality of the uploaded TikTok video.
If a video was uploaded in high resolution, such as HD, the downloader may allow you to save it in the same quality.
However, if the original video is low quality, it cannot be enhanced beyond its source resolution.
Some tools offer multiple resolution options, but these are usually limited to what TikTok provides.
In certain cases, higher resolution options may be compressed to reduce file size.
The performance also depends on the downloader you are using and its features.
Overall, Download Video TikTok MP4 supports available resolutions but cannot exceed the original video quality.
