Frequently Asked Questions

How do I merge PDF files?

Drop your PDF files into the upload area, arrange them in your preferred order using the drag handles or move buttons, then click "Merge." The combined PDF downloads automatically. All processing happens in your browser.

Can I reorder the PDFs before merging?

Yes. After adding your files, use the up/down arrows to rearrange them in any order before merging. The final PDF will follow the order you set.

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

No hard limit. You can merge as many PDF files as your browser memory allows. For most documents, merging 20-50 files at once works well.

Are my files secure?
