MP4: 720 × 1280

7.296 seconds - How the time was measured
- From sending the request until the complete MP4 response body arrived.
These are measurements of the files returned by those individual requests, not a promise that every Reel will download at either resolution. The 720 × 1280 sample is a real 720p-class output; the other sample returned 1080 × 1920. Vidlune does not upscale a returned video, so a smaller file is not turned into a higher-resolution one.
I paired the 720p result that raised the question with a Reel already used in an earlier production smoke test; that earlier response had video and audio, but no resolution measurement, so it serves as a prior-success reference, not a resolution baseline.
Repeatable test details
Where these measurements came from
Both requests were sent directly to https://ig-reels-downloader.com/api/download from machine DESKTOP-OC01O77, running Windows 11 Pro (OS version 10.0.28000) with Node.js v24.19.0. The client posted the public Instagram URL and MP4 format, then timed receipt of the full response. No browser was used.
The figures are specific to these URLs, this machine and this request path on September 23, 2026. Repeating the test later, or from another machine or network, can produce a different result.
Internally, Vidlune first tries an MP4 video stream with a separate M4A audio track; if that combination is unavailable, it falls back to compatible alternatives and requests an MP4 remux.
Service limits
A download limit is separate from video quality
Vidlune permits up to three successful downloads per IP address in a rolling 24-hour period. Failed attempts do not count. These two measurements were taken without changing the client IP or bypassing that limit.
There is also a 200 MB maximum output-file size. Neither limit changes the resolution available in a particular public post. For a fresh test, use the Instagram Reels Downloader; for supported links and other service boundaries, see the Instagram video download guide.
What the sample can tell you
A 720p result is not evidence that every Reel is 720p
One tested post returned 720 × 1280, while another returned 1080 × 1920. That is enough to show the two outputs were not identical; it is not enough to identify the cause for every Reel or to promise a particular result for a new link. The tool returns the compatible video it can retrieve and does not manufacture extra resolution.
