Frequently asked questions

What should I check before using the output?

Merging copies pages as they are; it does not OCR or make scanned text searchable. Very large files are limited by browser memory, and password-protected PDFs may fail to open.

What if a file or action is unsupported?

Check the input format and any visible error, try a smaller test case, and confirm the browser supports the required feature. Do not treat an empty output as a successful result.
