About Sizefit
Sizefit is a free tool that makes videos and images small enough to send. Every app has a size limit, and the error messages never say how to get under it. We wanted one place that knows the limits and handles the maths.
How it is different
The compression runs inside your own browser. We do not run servers that process your files, and there is no account to make. That keeps the tool free, fast and private.
How it pays for itself
The site shows a small number of ads, clearly separated from the tool. We keep them away from the download button so nobody clicks one by mistake.
