❓ Frequently Asked Questions
How do I merge PDF files online for free?
Simply upload your PDF files using the tool above, click the Merge PDFs button, and download your combined PDF. It is completely free with no sign up required.
Is there a limit to how many PDFs I can merge?
There is no fixed count in the interface, but very large files or batches can exceed the memory available to your browser. Try smaller groups if merging fails.
Are my PDF files uploaded?
The merge operation reads the selected files in your browser and does not send their contents to this site's API. Avoid shared devices for confidential documents and keep your originals.
Can I merge PDFs on my phone?
You can try it in a modern mobile browser. Large files may be limited by the memory available on your device.
Will the merged PDF have a watermark?
No, never. Your merged PDF will be completely clean with no watermarks added.
What does this merge tool preserve?
It copies pages from the selected PDFs into a new document. It does not provide editing, OCR, compression, or a way to unlock protected files.
🔧 Other Free Tools You May Like
What happens when PDFs are merged
The merge tool reads each selected PDF in the browser, copies its pages in the order selected, and creates a new PDF for download.
Order and compatibility
Select files in the order you want them combined and confirm the final page sequence before sharing. Damaged, password-protected, unusually large, or unsupported PDFs may fail to load; this tool does not edit page content or remove restrictions.
Privacy and file limits
The merge code processes file bytes in the browser and does not upload the PDFs to the site's API. Files still use device memory, so very large documents may fail on memory-limited devices. Keep a copy of your originals.
