Offline video is genuinely useful: spotty train wifi, long flights, or just wanting a local backup of something you don't want to lose are all legitimate reasons to save a copy of a video you've watched online. But "you can" and "you should" aren't always the same question, so it's worth a quick gut-check before hitting download.
The simplest rule of thumb: only save videos you made yourself, videos explicitly marked as free to download by their creator, or videos you otherwise have clear permission to keep a copy of. Most platforms' terms of service draw a hard line between watching a video through their player and keeping a standalone copy of it — even when the technical option to download exists somewhere.
A few practical habits help:
- Check for a creator's own download or "save offline" feature first — many platforms build this in for exactly the use case you have in mind.
- If you're downloading for research, archiving, or criticism, keep in mind that fair use / fair dealing exceptions are narrow and vary by country — they're not a blanket permission slip.
- Never redistribute a downloaded video as your own or re-upload it elsewhere. Saving a personal copy and republishing it are very different things legally.
- When in doubt, ask the creator. Most are happy to grant permission for reasonable personal use if you simply ask.
None of this is legal advice — just a sensible starting point for treating other people's work the way you'd want your own treated. ## More Bilibili Download Guides
