Why Shorts files are so much smaller
A 30 second Short is often under 5 MB, while 30 seconds of a regular 1080p YouTube video can be 15 MB or more. Same platform, same stated resolution, three times the difference.
The reason is bitrate. Shorts are encoded for phone playback on mobile data, in a feed where the next video must start instantly. YouTube allocates them a much smaller data budget than a regular upload, which is invisible on a phone screen and quite visible on a monitor.
Resolution and aspect ratio
Most Shorts are 1080x1920 vertical. Some are 720x1280 when the creator uploaded from an older device or over a weak connection. A few are landscape videos that YouTube has cropped into the Shorts feed, and those download in their original shape rather than the cropped one you saw.
That last case surprises people. The crop is applied by the player, not stored in the file. If you save a Short that was really a landscape clip, you get the landscape original, which is arguably better source material anyway.
The audio question
Shorts using the platform's own audio library carry that track in the file, and that audio is licensed for playback on YouTube rather than for redistribution. Re-uploading a saved Short to Instagram or TikTok with the original sound intact is the fastest route to an automated copyright claim.
Shorts made with original audio have no such problem. If you are planning to reuse a clip, checking which kind you have takes a moment and saves an argument later.
Shorts versus the main downloader
This page and our main YouTube downloader run the same extraction, so either works. The difference is context: Shorts have their own limits, their own encoding, and their own link format, and lumping them in with two hour documentaries produces advice that fits neither.
If you are saving a long form video rather than a Short, the main YouTube page covers separate audio streams, 4K file sizes and the codec choices that matter at those resolutions.
Want just the audio?
Plenty of Shorts are saved for the sound rather than the picture: a voiceover, a pronunciation, a hook you are trying to identify. Keeping 20 MB of vertical video for half a megabyte of audio is wasteful, so try our YouTube Shorts to MP3 converter instead. Same link, same paste, audio track on its own.
The walkthrough of converting a Short to MP3 goes through the three methods that work, what bitrate to expect from the source, and the fixes for a download that comes back silent.
Everything above also applies to the rest of YouTube video downloads, and our piece on Shorts and watermarks goes further on the parts people get stuck on.
