Use the matching tool to start straight away. The download begins in your browser and shows its size and progress on the page.
The same link-based method works for Reels and for ordinary video posts. A Reel link contains /reel/ and a post link contains /p/. If a carousel mixes photos and videos, the video slides are what the downloader sees. It cannot save still photos, so use your device's screenshot or the original upload for those.
Instagram hides private accounts behind a login, and the downloader does not ask for your password and never will. That means posts from private profiles, Stories, Close Friends content and Highlights are out of reach. If a Reel opens when you are logged out in a private browser window, it is public and will work.
Reels are stored as vertical video, typically 720 x 1280 or 1080 x 1920. Instagram compresses everything on upload, so a download will not be sharper than what you see on screen, but it will be the full-resolution version rather than a screen recording. File sizes for a 30 second Reel are commonly in the single-digit megabytes.
Trending sounds and voiceovers can be saved separately. Choose the Audio (MP3) row, or open the Instagram to MP3 tool. The file is a 192 kbps MP3, handy for editing apps and presentations where you have permission to use the sound.
If you receive a message that the post cannot be found, make sure you copied the link from the post itself and not from a profile. Links from direct messages sometimes carry tracking parameters, which is fine. If the content is age-gated or has been removed, no tool can fetch it. Wait a minute between attempts if you have downloaded several clips in a row.
Reels belong to their creators, and a lot of them contain licensed music. Keep downloads for personal viewing, research or content you have been given permission to use, and always credit the original account when you share. Reposting without credit or permission can lead to takedowns and account strikes.
