The default cap
20 MB is the number people actually remember: class portals, many chat apps, “small enough to mail”. VideoToSize is built around that stamp.

20 MB is the number people actually remember: class portals, many chat apps, “small enough to mail”. VideoToSize is built around that stamp.
Drop the file in the browser trial if it is short. Anything bigger belongs in the desktop app. VideoToSize plans a target bit rate from the duration, then encodes H.264 on your computer. Nothing is uploaded.
Short clips usually still look fine. Longer 4K will soften because 20 MB cannot hold that much. We lower bit rate first, then resolution if needed. Preview the result and keep the original.
It will be at or under 20 MB. We retry at a lower bit rate if the first pass overshoots. We never truncate the file.
HandBrake is stronger and free. We sell four size buttons, not an encoder GUI.
