Compress to fit a 20 MB limit
Twenty megabytes is a genuinely common ceiling. It is the default attachment limit in the Outlook desktop app, a frequent cap on web upload forms and support portals, and a typical maximum on many forums. It is tight but usable: two to three minutes of clean 720p video fits, which covers most short clips people need to attach or upload.
The tool budgets the bitrate from your clip's length and keeps the resolution as high as 20 MB allows, then checks the finished file really lands under the limit before handing it back. If you are attaching to Outlook specifically, remember that email encoding adds about a third to the size in transit, so the dedicated Outlook page targets a slightly lower real size.
Questions people ask
- How much video fits in 20 MB?
- Roughly 2 to 3 minutes at 720p for typical footage. High-motion clips use the budget faster. For longer video, trimming keeps quality higher than compressing everything into 20 MB.
- What uses a 20 MB limit?
- The Outlook desktop app defaults to 20 MB, and many upload forms, support portals, and forums cap there too. If you are emailing through Outlook, aim a little lower to allow for email encoding overhead.
- Is my file uploaded?
- No. Compression runs entirely in your browser, on your device, and nothing is sent to any server.
