Sized for the App That Rejected the File
This is not a general quality slider. It aims at a send limit.
720p by default
The picture is scaled to 720p so a short clip can actually fit the limit. You can keep the original size if you prefer.
Privacy-first
Compression runs on your device. For a general quality slider, use the video compressor.

WhatsApp and Email Size Questions
Limits change by app. These are the sizes people usually need.
What size does WhatsApp accept?
A video sent inside the chat is often limited to about 16 MB. Larger files may need to be sent as a document, which the other person has to download. This tool aims at 16 MB.
Are my files uploaded to your servers?
No. Compression runs locally in your browser. Your files are processed on your device and are not sent to Videoradius servers.
What about email?
Gmail attachments stop at 25 MB. Choose Email to aim the file at that size. Very long videos may still need a lower resolution or the desktop compressor.
What is the maximum file size?
Each file can be up to 300 MB. Larger files may take longer depending on your device, browser, and chosen settings.
Will the file always land under the limit?
The encoder targets that size. A very long clip can still finish a bit over it. For a hard limit on large files, use the Videoradius Video Compressor desktop app.
Need Pro Compression on Windows?
