The saved video has no sound.

Check that you used the Video tab rather than Audio, and that your player is not muted. If it is genuinely silent, try a different quality option — some platforms publish certain renditions as picture-only — and report it through the contact page if none of them carry sound.

Why is the file so much larger than the video looked?

Higher resolutions carry a lot more data than the on-screen size suggests, particularly for anything with motion. Each option shows its size before you commit, so you can pick the trade-off rather than discover it afterwards.

Quality, file size and playback problems

In short

The quality list shows what the source actually has — if 4K is not there, the original is not 4K. A file that will not play is usually a player that does not know the format rather than a broken download.

The quality you want is not listed

The list is not a menu of what we could produce; it is what the platform published. If the highest option is 720p, the upload was 720p, and no download can add detail that was never recorded.

Platforms also re-encode aggressively. A video shot in 4K and posted to a social app is often stored at a fraction of that, and what you can save is the stored copy rather than the camera original.

The short ad before high-quality and photo downloads

Top-resolution video and photo downloads show a short ad first. Those are the heaviest requests to serve, and ads are what pay for the free tier existing at all.

Pro removes it. So does choosing a lower resolution, which is often genuinely the better call for a clip going straight to a phone screen.

The file downloaded but will not play

Try it in VLC before assuming the file is damaged. Some phone galleries and older players refuse formats they do not recognise even when the file is perfectly intact, and a file that plays in VLC is a player problem, not a download problem.

An audio download that plays with no picture is working as intended — the Audio tab extracts sound only. If you wanted the video, download it again from the Video tab.

The download stopped partway

Interrupted downloads are almost always the connection dropping mid-transfer, and a partial file will not play. Delete it and start again rather than trying to resume it.

Large 4K files on a mobile connection are the usual casualty. If it keeps failing on the same video, taking one step down in resolution generally succeeds.
