Unless you have a specific need (emergency offline viewing on a junk phone, extreme rural internet, or preserving nostalgia for early 2000s mobile video), the experience is poor. download highly compressed movies under 100mb work

If you have a large movie file and need to shrink it for a specific device, several tools can reach the 100MB target: How to Compress Video Without Losing Quality Fix: That is the limit of the format
Creating a "highly compressed movie under 100MB" is a feat of data engineering rather than an entertainment optimization. It relies on the extreme efficiency of the H.265 codec, aggressive resolution downscaling to 240p/360p, and strict audio limiting. While technically functional and "workable" for file transfer, the viewing experience suffers from severe macroblocking and audio degradation. As HEVC and the emerging AV1 codec improve, the feasibility of low-bitrate video improves, but the 100MB constraint remains a severe bottleneck for visual quality.
Lowering the bitrate (the amount of data processed per second) reduces file size but significantly lowers video quality [7]. Risks and Limitations
