Overview
If your video is stuck uploading or won't complete, the cause is usually your internet connection, browser settings, or the video file itself. This article walks you through how to diagnose and fix upload issues on desktop and mobile.

Known Limitations — Read This First
Before troubleshooting, check whether your video runs into one of these hard limits:
- Maximum file size: 2GB. Videos larger than 2GB cannot be uploaded. If your file exceeds this, compress it or re-export at a lower resolution before trying again.
- 4K video is supported but not recommended. BombBomb accepts 4K recordings and uploads, but downscales them to 1080p during processing. 4K files take significantly longer to upload and encode, which can cause uploads to appear stuck or stalled. If you're experiencing hanging uploads, re-record or re-export at 1080p or lower before uploading.
Step 1: Check Your Internet Speed
A slow upload connection is the most common cause of failed uploads. BombBomb recommends a minimum of 10 Mbps upload speed.
- Go to speedtest.net and click Go.
- Once the test finishes, check your Upload Speed.
- If it's below 10 Mbps, try switching to a wired Ethernet connection or moving closer to your router. You can also contact your Internet Service Provider for help improving your connection speed.
Tip: A wired Ethernet connection is always more stable than Wi-Fi for video uploads.
If your speed looks fine, move on to the steps below for your device.
Troubleshooting on Desktop
1. Refresh and Try Again
Close BombBomb Engage in your browser, reopen it, and try the upload again. This clears any temporary session issues.
2. Clear Your Browser Cache
Cached data can interfere with uploads. Follow the steps for your browser:
Google Chrome (recommended browser)
- Click the three-dot menu in the top-right corner.
- Click Settings.
- Click Privacy and security.
- Click Delete browsing data.
- Set Time range to All time.
- Check Browsing history, Cookies and other site data, and Cached images and files.
- Click Delete data and wait for Chrome to finish.
Mozilla Firefox
- Click the three-line menu in the top-right corner.
- Click Settings.
- Click Privacy & Security.
- Under Cookies and Site Data, click Clear Data.
- Check both Cookies and Site Data and Cached Web Content.
- Click Clear and confirm.
Microsoft Edge
- Click the three-dot menu in the top-right corner.
- Click Settings.
- Click Privacy, search, and services.
- Under Clear browsing data, click Choose what to clear.
- Set Time range to All time.
- Check Browsing history, Cookies and other site data, and Cached images and files.
- Click Clear now.
Safari (Mac only)
- In the menu bar, click Safari > Settings (or Preferences on older versions).
- Click the Privacy tab.
- Click Manage Website Data, then Remove All.
- Confirm by clicking Remove Now.
- Alternatively, go to Develop > Empty Caches (you may need to enable the Develop menu first under Advanced settings).
After clearing cache, reopen BombBomb and try uploading again.
3. Disable Browser Extensions
Ad blockers, privacy shields, and other extensions can interfere with uploads. Temporarily disable your extensions and try again. If the upload succeeds, re-enable extensions one at a time to find the culprit.
4. Try a Different Browser
If the issue persists, try uploading in a different browser. Chrome, Edge, and Firefox are fully supported. Safari should work in most cases, but if you're experiencing upload issues specifically in Safari, switch to Chrome or Edge first.

Frequently Asked Questions
My upload starts but never finishes. What's wrong?
The most common causes are a slow internet connection, a file that's too large, or a 4K video that's taking a long time to process. Check your upload speed, confirm your file is under 2GB, and if you recorded in 4K, re-export at 1080p and try again.
Is there a maximum video file size?
Yes — 2GB. Files larger than this can't be uploaded. Compress your video or re-export at a lower resolution before trying again.
I recorded in 4K. Why is my upload stuck?
BombBomb accepts 4K but downscales it to 1080p, which makes encoding take much longer than usual. Re-record or re-export at 1080p or lower for a faster, more reliable upload.
Do I need a specific browser?
Chrome is recommended. Edge and Firefox are fully supported. Safari works in most cases, but if you're having upload issues in Safari specifically, try Chrome or Edge instead.
Why won't my video upload on mobile data?
Mobile data connections are less stable than Wi-Fi and can cause uploads to stall or fail. Switch to Wi-Fi when uploading, or record with your native Camera app and upload later when you have a reliable connection.
I've tried everything and it's still not uploading. What now?
