Q. My video is too big for YouTube. How do I get it uploaded from my iPad.

I’ll add one more thing here, as the discussion about the iPad shifts the tools we are talking about. I'd consider HandBrake as a desktop option, but there is no current iPadOS version of the app. If you are going to upload video directly from the iPad, you have a few options for video compression on the iPad. 1. Compress the video directly on iPad: As previously noted, there are several good online compressors that work in Safari without the need to download and install software. For example, ConvertYard (convertyard.com/compress-video) is a great, free, online compressor that compresses videos locally in your browser – meaning your video will never leave your iPad. You simply set a size (e.g., 500MB, the size of YouTube uploads) and ConvertYard will re-encode the video to that size. 2. Trim before compressing. Using the iPad’s built-in Photos app to trim the start and end of your video can help reduce the overall file size. Even trimming 30 seconds from the front of a 4K video can help significantly reduce the overall file size. 3. AirDrop or upload to a Mac and then use HandBrake on the desktop to compress the video and upload it. This is usually more stable than uploading a large file on the iPad using Safari. Just a side note: When you upload your video to YouTube, they re-encode it anyway, regardless of what you sent them. Hence, it won’t hurt to re-encode that 4K clip to 1080p on your iPad with reasonable bitrates first, before you struggle to upload the original file. This will save you a lot of trouble!
