Vimeo without installing anything
A browser page. Nothing to install.
By using this site you confirm you have the right to download the file you request.
The command-line answer, and why this is not it
The usual recommendation for Vimeo is a terminal tool and a page of flags. It works and it is genuinely good software — it is also a runtime to install, a binary to keep updated, and a syntax to re-learn between uses, for one video.
This is the same fetch in a tab. For anyone who will do it twice a year, that is the right size of tool.
What it will not get past
Password-protected videos and private links. Those are Vimeo’s access controls working as intended, and no local program gets past them either — this is worth saying because a lot of software is sold on the implication that it does.
Frequently asked questions
Is there a file size limit?
Long videos work; they take longer and arrive larger.
Does it work on a Mac?
Yes. It is a web page — the operating system does not come into it.
