Frequently Asked Questions

Can I reorder PDFs before merging?

Yes. Arrange the uploaded list, then merge files in that order.

How many PDFs can I merge?

Up to 20 files are recommended for browser stability. Large PDFs may take longer.

Is the merged PDF uploaded to a server?

No. Merging runs in your browser and the result is saved only when you download it.

Supported Scope

Merge PDF, split PDF, image to PDF, and PDF to JPG run in your browser.

Encrypted, permission-restricted, or very large PDFs may fail because browser memory is limited.
