FAQ
Q: How many images can I merge into one PDF?
A: No limit. Merge as many images as you need. Processing happens locally, so large collections depend on your device’s memory.

A: No strict limit. Processing is browser-based, so performance depends on your device. Most images up to 50MB process smoothly.
