Compress a video to 10 MB

Frequently asked questions
How long a video fits in 10 MB?
About a minute and a half at a watchable 720p, or longer at a lower resolution. Size is set by bitrate and duration, so shorter clips look better.
Is there a watermark?
No. Free compression has no watermark and no sign-up.
Is my video uploaded anywhere?
No. Altols uses your browser's built-in video encoder, so the video is processed on your device and never leaves it.
Is there a size limit?
Free compression works on videos up to 100 MB. For larger videos, up to 1 GB, a 24-hour pass costs $2.99 USD.
