What to know
- Gmail and Outlook.com both list 25MB, but email adds about a third to a file when it sends it. Around 18MB is safer.
- Work accounts are stricter. Exchange defaults to 10MB. The recipient's limit counts too, so if theirs is lower the message fails.
- At 18MB, a 16:9 video stays at 720p up to about 67 seconds, and at 480p up to about 2.5 minutes.
Questions
- Is my video uploaded?
- No. It is processed on your device and never sent to a server.
- Why is it slower than other sites?
- Your device does the work instead of a server. There is no upload wait, but encoding takes longer on older phones.
- Why did my video come out at a lower resolution?
- A small file has room for only so much detail. Rather than a blocky 1080p video, the tool scales it down so it looks clean. Pick a bigger size or trim the clip to keep more resolution.
- It says my browser cannot do it.
- Use a current Chrome, Edge or Safari. Not every browser can read every video format.
