Living with the 20-page cap

Longer works split at natural seams into “Part 1/2/3” files — which email gateways and upload portals prefer anyway. The multi-page guide covers batch workflows.

Frequently asked questions

Is there a photo size limit?

Very large photos are automatically downscaled to the working resolution — hand over your 48 MP shot without worry; the pipeline takes what it needs.

Any daily bandwidth quota?

After the one-time engine download, scanning uses no network at all — there’s nothing to meter.
