The short version: a Reel stuck on the preparing screen is almost always down to a weak or unstable connection, a video file that's too large or too long for the upload to complete cleanly, or the Instagram app's cache getting stuck mid-process. Switch to a strong Wi-Fi connection first and give it a couple of minutes before you touch anything else.
What's really happening
When you tap share on a Reel, Instagram isn't just uploading a video file, it's processing it: compressing it, applying any effects or text you added, matching it to audio, and preparing several versions for different parts of the app before it ever appears on your profile. The preparing screen covers all of that work. Most of the time it takes seconds. When it hangs, it means one part of that chain has stalled, usually because the upload itself is struggling, the file is heavier than the connection can push through smoothly, or the app has lost track of where it got to.
This is stressful because it feels like your Reel might be lost, but in nearly every case the draft is recoverable if you handle it the right way, which mostly means not force closing the app the moment it looks stuck.
The three most common causes
1. A weak or unstable connection
Reels are video files, and even a short one can be tens of megabytes once effects and audio are layered in. If you're on patchy mobile data, or Wi-Fi that keeps dropping in and out, the upload can start, stall, restart, and get stuck in a loop that looks like it's frozen but is really still quietly trying.
2. The file is too long or too large
Instagram has limits on Reel length and file size, and while most phones keep video within range automatically, a Reel with a lot of clips, heavy effects, or a long total length can end up right at the edge of what will upload smoothly. The preparing stage is where this tends to bite, because that's when the file is really being compressed and pushed to Instagram's servers.
3. A stuck app cache
Instagram keeps a local queue of things it's uploading, and occasionally that queue gets corrupted or confused, often after a previous failed upload that didn't clear correctly. When that happens, the app can get stuck trying to process a Reel that, from your side, looks like a fresh attempt but is really tangled up with leftover data from before.
Fixes to try, in order
- Wait it out on a strong Wi-Fi connection for two to three minutes. Before doing anything else, connect to reliable Wi-Fi if you're not already on it, and leave the app open and in the foreground. On both iPhone and Android, this is simply a case of checking your Wi-Fi toggle is on in Settings and that you're connected to a network you trust. Genuine processing delays, especially for longer Reels, can take a minute or two and resolve on their own. If it's still stuck on preparing after three minutes, move to the next step.
- Move the app to the background and check the notification. Don't force close it yet. On iPhone: press the home button or swipe up gently to send Instagram to the background without closing it, then check if a progress notification appears. On Android: tap the home button the same way. Reels sometimes continue uploading in the background even though the in-app screen looked frozen. Give it another minute, then reopen Instagram and check your profile or drafts. If the Reel has posted, you're done. If it's still stuck when you reopen, go to the next step.
- Save the Reel as a draft before closing anything. If there's a back arrow or close option visible on the preparing screen, use it rather than force closing the app, since this usually prompts Instagram to save your work as a draft rather than losing it. On both iPhone and Android this appears as an on-screen prompt asking if you want to save or discard. Choose save. If no such prompt appears and the screen is completely frozen with no buttons responding at all, you'll need to force close, but expect to find the Reel waiting in your drafts rather than fully lost.
- Force close Instagram and reopen it. On iPhone: swipe up and hold to open the app switcher, find Instagram, and swipe it away, then reopen from the home screen. On Android: go to Settings, then Apps, then Instagram, then tap Force Stop, then reopen it. Check your drafts folder from the create screen before doing anything else, since your video will very likely be sitting there. If it's not in drafts and the video is gone, you'll need to re-edit it from your camera roll.
- Clear the app's cache, then re-upload the draft. On Android: go to Settings, then Apps, then Instagram, then Storage, then tap Clear Cache, which does not delete your account data or posts. On iPhone there's no separate cache clear, so offload the app instead: Settings, then General, then iPhone Storage, find Instagram, and tap Offload App, then reinstall from the App Store. Open your draft, and try posting again. If it hangs on preparing again at the same point, the file itself is likely the problem, so move to the next step.
- Trim the Reel or export it shorter and re-import. If the same Reel keeps sticking on preparing across multiple attempts and on a good connection, shorten it, either by cutting a few seconds of footage or reducing the number of clips and effects stacked on top of each other, and try again. A shorter, lighter file is far less likely to hit whatever limit is causing the stall. If a shorter version of the same content uploads fine, you've confirmed the original file was simply too heavy.
Will I lose the Reel if I have to force close the app
Usually not, but it depends on when you close it. If Instagram had already saved a draft version, either automatically or through a save prompt, it will be sitting in your drafts when you reopen the create screen. If the app freezes so completely that no options respond at all and you have to force close without any save prompt, there's a real chance the specific edit, effects and all, is lost, though the original clips in your camera roll are untouched. This is exactly why it's worth waiting the extra minute or two before forcing a close, rather than doing it the second the screen looks stuck.
If it happens on every single Reel you try to post
A one-off stuck upload is normal and usually connection related. If literally every Reel you try to post gets stuck on preparing regardless of length or connection, that points to a deeper app or account issue rather than a single file problem. Update the app fully, restart your phone, and if it still happens, check whether other people posting from the same Wi-Fi network are having the same problem, since some shared or restricted networks quietly block the kind of connection Instagram needs to upload video correctly.

Frequently asked questions
How long should I wait before assuming it's really stuck?
Give it two to three minutes on a strong connection first. Reels with a lot of effects or a longer runtime truly take longer to process than a simple clip, and closing too early is the main reason people lose drafts.
Does mobile data cause this more than Wi-Fi?
Generally yes, especially on a weak signal, because the upload needs a steady connection rather than just a fast one. A stable four bar mobile signal will often outperform patchy Wi-Fi.
Can I edit the Reel while it's stuck and try again?
Not while it's actively processing. Wait until it's either posted, saved as a draft, or you've force closed the app, then edit the draft version before attempting to post it again.
Why does it only happen with Reels that have music added?
Audio syncing adds another processing step on top of the video itself, which increases both file size and the chance of a stall on a weak connection, so Reels with music are more likely to stick than silent clips.
Is there a file size limit I should stay under?
Instagram doesn't publish an exact number that's guaranteed to work every time, but keeping your Reel under a minute or so with a moderate number of effects gives you the best chance of a clean, fast upload.
