Frequently asked questions
How do I merge PDF files online?
Add two or more PDF files, arrange them in the order you want using the up and down buttons, then click Merge PDFs and download the combined document.
Are my PDF files uploaded to a server?
No. The merge happens entirely in your browser using your device's memory, so your PDF files are never uploaded and nothing leaves your computer.
Is there a limit on the number of PDFs I can merge?
There's no fixed limit. You can combine as many PDF files as your device has memory to handle; very large or numerous files just take a little longer.
Can I change the order of the PDFs before merging?
Yes. Use the up and down arrows next to each file to reorder them, and the remove button to drop any file before you merge.
What file format can I merge?
This tool merges PDF files. Add multiple .pdf documents and they're combined into one PDF, keeping every page from each file.
Does merging change my original PDF files?
No. Your original files stay untouched on your device. The tool creates a new merged.pdf that you download separately.
