Frequently asked questions
How do I merge several PDFs?
Click the upload area or drag your PDF files onto it. Put the files in the order you want with the arrow buttons and click ‹Merge›.
How many PDFs can I merge at once?
There is no fixed limit – you can merge as many PDF files as you like. With very many or very large files, the processing time depends on your device.
Can I change the order of the PDFs?
Yes. After adding the files, you can rearrange them with the arrow buttons (▲/▼) before merging.
Are my PDFs uploaded to a server?
No. Merging happens entirely in your browser. Your files never leave your device – ideal for confidential documents.
Is the formatting kept when merging?
Yes. All pages are copied 1:1, and formatting, images, links and forms are fully preserved.
