Frequently Asked Questions

How do I merge PDF files?

Simply select multiple PDF files using the file picker, arrange them in your desired order using the up/down arrows, and click 'Merge PDFs'. The tool will combine all files into a single PDF document.

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

There's no strict limit, but for optimal performance, we recommend merging up to 20 PDF files at once. For larger batches, consider merging in smaller groups.

Can I change the order of PDFs before merging?

Yes! Use the up and down arrow buttons next to each file to rearrange the order. The merged PDF will follow the order shown in the list.

Are my PDF files secure?

Absolutely! All PDF processing happens locally in your browser. Your files are never uploaded to our servers, ensuring complete privacy and security.

What happens to bookmarks and links in merged PDFs?

The merge process preserves the content of each PDF, but bookmarks and internal links may not work correctly in the merged document. External links should remain functional.
