Frequently Asked Questions

What is CBZ?

Zipped comic-book images — sequential pages in one handy archive.

Page order?

Natural numeric filename sort (page2 before page10), exactly as archived originally.

Quality preserved?

No — every page is rasterized through canvas and re-embedded as PNG, so bytes change and animation flattens. “Match Image” keeps pixel dimensions; Comic (477×738pt) and Manga (360×540pt) presets reframe instead. Ranges like “1-10” or “1,3,5-8” select pages.

Is my comics uploaded anywhere when using CBZ to PDF?

No — conversion runs locally in your browser; unlimited saves on local tools.
