Can't Email a Video? Here's Why (And the 3-Second Fix)
Gmail and Outlook.com both cap at 25 MB, but they count the base64-encoded payload, not the source file. Squash targets 18 MB so it actually attaches.
Why can't I email a video?
Gmail caps attachments at 25 MB. Outlook.com at 25 MB. But there's a gotcha almost nobody knows: those limits are enforced on the base64-encoded payload, not your source file. Base64 inflates attachments by about 33%. A 20 MB video becomes ~27 MB on the wire, and Gmail bounces it silently. A single minute of 1080p phone video is easily 100+ MB to start with, so you need real compression and a 25-MB-safe target of around 18 MB.
What are the requirements?
How do I fix this?
Drop your video into Squash and select Email. Squash compresses to under 18 MB at 720p H.264 High. After base64 encoding, the file lands around 24 MB on the wire — safely under Gmail and Outlook.com's 25 MB caps. No cloud links, no "view in Drive" nonsense.
Email compression is included in the free version. Squash Pro ($29) removes the 60-second limit and branded end card.
