It looks like you’re referencing a MakeUseOf article about Blip as a very fast way to move huge files. I don’t have live access to that article, so I can’t see exactly which “Blip” service they’re discussing or how it’s implemented, but I can give some general guidance on tools like this.
General idea behind “too fast” large-file tools
Services that feel “suspiciously fast” for big files usually achieve that by one or more of these:
Peer‑to‑peer (P2P) transfer: Data goes directly between sender and receiver instead of via a slow cloud relay, so speed is closer to your actual upload/download limits.
No/low server storage: The server only coordinates the connection and maybe metadata; the bulk data streams directly between peers.
Parallel connections / chunking: File is split into pieces and transferred over multiple connections at once.
Compression (sometimes): If the files compress well (e.g. text, some images), it can appear much faster because you’re sending fewer bytes.
That can legitimately feel “too fast” compared to traditional “upload to cloud, then recipient downloads” services.
What to check before trusting it
Before using any new large-file tool (including Blip) for important or sensitive data, I’d look at:
Encryption
– Is it end‑to‑end encrypted (E2EE), or can the service provider theoretically see your files?
– Do they clearly document the crypto they use?
Where does the data actually go?
– Is it P2P only, or do files sit on their servers for some time?
– If stored, for how long and in what region?
Open source / transparency
– Is the client/server code public or at least well‑documented?
– Do they explain the architecture (relay servers, STUN/TURN, etc.)?
Limits & controls
– Size limits, speed caps, link expiry options, passwords, etc.
Reputation & ownership
– Who runs it? Is there a clear company or developer behind it?
– Any clear privacy policy / terms of service?
Malware risk
– Like any file‑sharing method, it can deliver malware just as quickly as legitimate files.
– Always scan received files with a reputable AV and/or upload to VirusTotal before opening.
Practical safety steps if you want to try it
Use it first with non‑sensitive test files to check speed and reliability.
Read its official site/docs (and the article you linked) for how it handles encryption and storage.
Scan any file you receive with a trusted AV and optionally VirusTotal.
If you’re moving confidential data, prefer services that are openly documented and, ideally, open source.
If you can share what you’re mainly wondering about—speed claims, privacy/safety, or alternatives—I can give more targeted advice (e.g. compare it with things like Wormhole, Firefox Send‑style tools, Syncthing, etc.).
I have been using it for a while and its incredible: Reliable, fast, and simple to use. I use mainly to send files from my Galaxy S25+ to my Windows desktop. Its free, without any ad and works very very good. Cant recommend more!
