Frequently asked questions

How do I merge PDF files for free?

Drop your PDF files into the tool above, use the arrows to arrange them in the order you want, then click Merge PDFs. Your combined file downloads instantly — no account needed.

Are my files uploaded to a server when merging?

No. The entire merge process happens in your browser using JavaScript. Your PDFs never leave your device and are never sent to any server.

Can I reorder the PDFs before merging?

Yes. After adding your files, use the arrow buttons next to each file to move it up or down in the list. The final merged PDF will follow the order shown.

How many PDFs can I merge at once?

You can merge up to 30 PDF files at a time with a combined total size of 500MB. Processing happens in your browser, so speed depends on your device.

Will merging affect the quality of my PDFs?

No. Merging combines your original PDF pages without re-encoding or compressing them. Text, images, and formatting are preserved exactly as they are in the source files.
