Frequently Asked Questions

Is there a limit to how many PDFs I can merge?

No, there's no limit. Since processing happens in your browser, you can merge as many PDFs as your device memory can handle. Most modern devices can easily handle dozens of files.

Will the merged PDF maintain the original quality?

Yes, absolutely. Our tool preserves the original quality of all PDFs. No compression or quality loss occurs during the merging process.

Can I reorder the PDFs before merging?

Yes! You can drag and drop files to reorder them before clicking the merge button. The final PDF will follow your chosen order.
