Why is my iPhone video blurry on Android, and how to send it clearly

Between two iPhones, Messages sends the video over the internet as iMessage (the blue bubbles). Apple publishes no size limit for it, and in practice videos of around 100 MB are widely reported to go through. To an Android phone, Messages usually falls back to SMS/MMS (the green bubbles), which was designed for small pictures, not video.

The MMS size limit is set by each mobile carrier, and it is small: commonly somewhere between a few hundred kilobytes and a few megabytes. To make the video fit, it is re-encoded at a lower resolution and a much lower bitrate. That is the softness and blockiness you see. The loss happens on the way, so the file on your iPhone is still sharp.

A second cause can add to it. If the recipient opens the video in a chat app that recompresses on its own, such as WhatsApp, the picture is squeezed again.

Often it helps. RCS is the newer standard that replaces MMS between iPhone and Android, and iPhones support it from iOS 18. It carries media at a better quality than MMS. Whether it is on depends on your iOS version, your carrier, and the other person’s phone and carrier.

To check, open Settings and look for Messages, then RCS Messaging (the exact menu path differs between iOS versions). If the option is missing, your carrier or iOS version does not support it yet. Even with RCS on, a conversation falls back to MMS when the other side is not ready, so a blurry video can still happen.

From best quality to least effort:

1. 1In Photos, open the video and tap Share.
2. 2With iCloud Photos on, choose Copy iCloud Link. Otherwise, upload the video to Google Drive, OneDrive or Dropbox and copy its share link.
3. 3Paste the link into your message. The other person taps it and watches in their browser, at the original quality.

The trade-off is that the video plays from a web page rather than inside the chat, and it stays on that service until you remove the link. Our comparison of an iCloud link versus compressing helps you decide.

Then control the squeeze yourself. A video you shrink on purpose looks better than one the carrier crushes, and it is far more likely to arrive at all. Two things help whatever tool you use: trim the clip to the moment that matters (a few seconds fits much better than a minute), and expect a lower resolution.

A rough sense of scale: 1 MB is about 8 megabits, so a 10-second clip at that size gets under 1 Mbps for video and sound together. That is watchable on a phone, but 4K or a long clip cannot look good in a text message at any setting.

Minivid has two destinations for this. Text (MMS) fits the video to 1 MB, a size that goes through on almost every carrier, and caps the long side at 640 pixels. iMessage fits it to 100 MB at up to 1080p, a conservative figure for blue-bubble chats. Here is the flow:

1. 1Open Minivid and pick the video.
2. 2Tap Send via… and choose Text (MMS).
3. 3Minivid shows the size the result will have before it encodes anything. If the clip is too long to stay watchable at 1 MB, it says so; trimming is free and the estimate updates as you drag the handles.
4. 4Tap Compress and keep Minivid open while it runs.
5. 5Tap the send button to open the iOS share sheet and choose Messages.

Minivid never sends the message or signs in to anything; it writes a smaller copy on your iPhone and you send it yourself. The original is never modified, nothing is uploaded, and it works in airplane mode. Send via Text (MMS) and iMessage are part of Minivid Pro; in the free tier, Send via covers Zalo and Messenger.
