Secondly, all online video compressors have straightforward UI and even on-page guide so that every user can quickly get how to use. On the other hand, disadvantages cannot be ignored.
- Online video compressor relies on networking and bandwidth. The compression speed will be badly influenced by poor network condition. Certainly, it is completely useless if there is no network.
- Most online video compressor sites put lots of advertisements on pages. Some ads are safe but suck while some ads are very dangerous with virus affected.
- The free services always require something, like registration, email address, limited file size (usually <500MB), making it impossible to compress 4K or large-sized HD videos.

- Online video compressor only compresses videos only through conversion or small editing, which cannot achieve a best compression.
