Frequently Asked Questions

Is there a file size limit?

Since processing happens in your browser, the limit depends on your device's memory. For best results, we recommend merging files under 50MB each.

Can I merge password-protected PDFs?

Currently, our tool works with unencrypted PDF files. Password-protected documents need to be unlocked before merging.

Does the quality change after merging?

No, our PDF merger preserves the original quality of all documents. Text, images, and formatting remain unchanged.

How many PDFs can I merge at once?

You can merge as many PDFs as your device can handle. We recommend keeping total file size under 100MB for optimal performance.
