Compress an MP4 File Online
A smaller file uploads faster, fits under an email or chat attachment limit, and takes up less space in a shared drive. Upload the MP4 and download the compressed result when the tool finishes.
What you get:
- A smaller MP4 file you download directly, with no ScreenApp watermark added
- No software to install; a free ScreenApp account (Yes, free (no card))
- Works from a browser on a phone, tablet, or computer
How to Compress an MP4
- Upload your file: Drag and drop your MP4, or choose it from your device.
- Wait for processing: The tool uploads the file and runs compression on it.
- Download the result: Preview the file size before and after, then download the compressed MP4.
How much a file shrinks depends on its content: an MP4 of mostly static slides or a talking head compresses further than fast-motion footage. See how we measure accuracy for how ScreenApp evaluates its tools generally.
