About this tool
Encoding runs on your device with WebAssembly on one thread, so long or high-resolution videos can take several minutes. For tight targets the video is scaled down (as low as 360p) to keep quality acceptable.

Frequently asked questions
How accurate is the target size?
The bitrate is calculated from the duration with a safety margin, so the result usually lands slightly under 16MB; complex footage can vary.
Why is it slow?
The encoder runs in your browser on one CPU thread. A desktop is much faster than a phone.
Will it work on my phone?
Short clips usually work; large videos may run out of memory on phones.
Does it reduce resolution?
For small targets, yes, to keep the picture usable.
Are my files uploaded to a server?
No. Everything runs inside your browser on your own device, so your files and text are never sent anywhere.
Is it really free?
Yes. There is no sign-up, no watermark and no limit on how often you use it.
Does it work on my phone?
Yes. It works in any modern browser on phones, tablets and computers. Very large files may be slow on older phones.
