Frequently Asked Questions

Are my PDF files uploaded to a server?

No. All merging happens in your browser using JavaScript. Your files never leave your device.

Is there a limit on the number of files?

No limit. Merge as many PDFs as you need. The only constraint is your browser's available memory.

Can I reorder the files before merging?

Yes. Use the arrow buttons to move files up or down in the list before merging.

Will the merged PDF lose quality?

No. We copy pages directly from the original PDFs without any re-encoding. Quality is preserved exactly.
