For YouTube · Windows · Free

Grab the whole stream,
not the small combined one.

YouTube keeps its high-resolution video and its audio as two separate files — most downloaders only hand you the small pre-merged version. Grabline pulls both full-quality streams straight from the source and merges them losslessly. 4K stays 4K. 8K stays 8K.

How it works

Three clicks, no setup

Grabline fetches its download engine into its own app folder on first run. Nothing goes into Windows itself, and uninstalling takes it all with it.

01

Paste a link

Any YouTube video, or a whole playlist — Grabline queues every video in it.

02

Pick a take

Every resolution the video actually has, with real file sizes before you commit.

03

Get one file

Video and audio merged losslessly. Nothing re-encoded, nothing lost.

Grabline is free. All of it.

No ads, no bundled software, nothing held back — 8K, playlists, subtitles, five downloads at once. If it saved you time, you can chip in. Entirely optional.

FAQ

Before you ask

Does this cost anything?

No. Every feature is free — the donate button above is just that, a donation.

Is it safe?

Grabline only talks to YouTube and its own download engine. No ads, no bundled installers, nothing added to Windows outside its own app folder.

What about YouTube's Terms of Service?

Downloading from YouTube goes against its Terms of Service, and most videos belong to someone else. Keep to your own uploads, Creative Commons material, or content you have permission to save.

Mac or Linux?

Windows only, for now.
