A 16 MB target is the practical cap for WhatsApp video on most phones, and a common limit for other mobile messengers. A single short phone clip usually exceeds it, which is why the "file too large" message is so common.
This page sets the 16 MB target so your clip sends on the first try. For files under 300 MB everything happens locally in your browser — no upload, no waiting.
Why 16 MB?
16 MB is the standard mobile send limit for WhatsApp video and a common cap for other messengers, so it is a reliable target for sharing.
Will a longer video fit 16 MB?
Short clips fit easily at good quality. Very long videos may drop resolution to fit — trim to the key part for the sharpest result.
Does it work for apps other than WhatsApp?
Yes. Any service with a 16 MB or higher limit will accept the result.
Do I need to install anything?
No. It runs in your browser; files under 300 MB stay on your device.
Is it free?
Yes. The free plan compresses up to 300 MB locally with no watermark.
