Media File Size Overview

The tables below contain the median sizes of files taken by our SDKs. In 95% of cases, the mean sizes are comparable with median, but, in 5%, files might be significantly larger than expected.

The file size of the best shot, as the best shot is also a single frame, is equal to the file size of the One shot gesture.

For each gesture, you can see whether it counts as passive or active Liveness.

Native SDKs

We recommend avoiding the One Shot gesture whenever possible, as it tends to produce less accurate results.

Gesture	Android	iOS	Liveness
Simple selfie	2.01 MB	0.92 MB	Passive
One shot	1.43 MB	0.26 MB	Passive
Scan	2.69 MB	4.52 MB	Passive
Smile	2.21 MB	2.38 MB	Active
Blink	1.24 MB	1.96 MB	Active
Head turned left	2.43 MB	2.79 MB	Active
Head turned right	2.53 MB	1.67 MB	Active
Head tilted downwards	1.67 MB	1.93 MB	Active
Head lifted up	2.41 MB	1.95 MB	Active

Web SDK

Scan	4.6 MB	2.6 MB	Passive
