Do I need to select every pair in a large PDF?

No. Consecutive pages are paired automatically. 100 pages become 50 A3 sheets, and you can jump to any sheet.

What happens to an odd final page?

The other slot on the final A3 sheet remains blank. The last page is retained.

Are non-A4 pages cropped?

After confirmation, their entire content is fitted proportionally into the slot. This may leave blank space.

Are files uploaded or charged against a quota?

Files are processed locally in your browser without consuming a cloud trial or daily quota. One complete A3 PDF is generated, originals are retained, and the actual result can be previewed before downloading.
