Download YouTube in 1080p and 4K
If a "free" YouTube downloader caps you at 720p, it is grabbing the old pre-merged stream because that is the only one it can serve without extra work. YouTube delivers 1080p, 1440p, and 4K as separate video and audio files, so they have to be merged. VidSnag merges them locally with bundled ffmpeg, so it gives you real 1080p and 4K instead of the 720p ceiling.
It is one of the most common complaints about online downloaders: the highest option in the list is 720p, even on a video YouTube clearly plays in 4K. This is not a bug or a hidden paywall. It is a side effect of how YouTube stores high-resolution video, and it is exactly the part a desktop app handles that a website usually will not.

YouTube does not store a single finished file for each video. It uses adaptive streaming (DASH), where the picture and the sound are kept as separate streams that your player combines on the fly. There is one exception: a small set of older "progressive" formats that bundle video and audio into one ready-made file. Per the yt-dlp documentation, that single combined progressive format tops out at 720p; everything above 720p, including 1080p, 1440p, and 4K, exists only as separate video-only and audio-only DASH streams.
That is the whole catch. An online tool that wants to skip work hands you the pre-merged 720p progressive file, because anything sharper would mean downloading two streams and stitching them together with a tool like ffmpeg on their own server, for every visitor. That is costly at scale, so most sites simply do not, and 720p becomes the silent ceiling.
A desktop app does the merge on your machine instead. It pulls the high-resolution video stream and the matching audio stream, then combines them locally into one file. The cost moves to your computer, which barely notices, and the 720p ceiling disappears.
What quality you actually get
Because VidSnag merges the streams for you, the quality you can save matches what the uploader actually published:
- 4K (2160p): if the video was uploaded in 4K, you get the real 4K file, not an upscale.
- 1440p (2K): the in-between resolution online tools almost never expose.
- 1080p: true Full HD, merged from the separate video and audio streams.
- 720p and lower: still available when you want a smaller file or a quick clip.
- MP3 audio: pull the audio stream on its own and save it as an MP3.
How to download YouTube in 1080p or 4K
- Get VidSnag. Download and open the app. ffmpeg is bundled, so there is nothing else to install and no account to create.
- Paste the YouTube link. Copy the URL from your browser or the Share button and drop it into VidSnag.
- Pick a high resolution. Choose 4K, 1440p, or 1080p from the list. You see the full range the video offers, not just a capped 720p option.
- Download and merge. VidSnag fetches the separate video and audio streams and merges them locally into one file at the resolution you picked.

Why a desktop app gets full quality
The short version: the 720p cap is about who does the merging. A website avoids the cost of combining two streams for every visitor, so it serves the one pre-merged file that happens to stop at 720p. A local app does the merge on your own machine, where it is essentially free, so it can reach for the highest video stream the upload offers. That is also why a desktop tool keeps working when a site silently downgrades you.

Frequently asked questions
Why does my YouTube downloader only go up to 720p?
Because it is serving YouTube's pre-merged progressive stream, which tops out at 720p. Anything higher is stored as separate video and audio that must be merged, and many online tools skip that step to save server cost.
How does VidSnag get real 1080p and 4K?
It downloads the separate high-resolution video stream and the matching audio stream, then merges them locally with bundled ffmpeg into one file at the resolution you chose.
What is a DASH stream?
DASH is YouTube's adaptive streaming format, where picture and sound are stored as separate streams instead of one combined file. All resolutions above 720p are DASH-only, which is why they need merging.
Do I need to install ffmpeg myself?
No. ffmpeg is bundled inside VidSnag, so the merge happens automatically with nothing extra to set up.
Can I really download YouTube in 4K?
Yes, if the video was uploaded in 4K. VidSnag saves the real 4K file, not an upscaled 1080p one.
Will the merged file have sound?
Yes. The audio stream is merged in with the video, so you get a single normal file with picture and sound together.
Is VidSnag free?
Yes. Every feature is included with no trial or paywall, and it is funded by optional donations rather than ads.
Does this work on Windows 10 and 11?
Yes. VidSnag runs on both Windows 10 and Windows 11, with no account or sign-up.
