Frequently Asked Questions
How do I merge PDF files into one document?
Drag your PDF files onto the drop zone (or click to choose them), arrange them into the order you want with the up and down buttons, then click Merge PDFs. A single combined merged.pdf is created instantly and downloaded to your device.
Are my PDF files uploaded to a server?
No. Everything happens locally in your browser using your device's own processing power. Your files are never sent anywhere, which makes this safe for contracts, statements and other confidential PDFs. You can even use it offline once the page has loaded.
Is there a limit on how many PDFs I can merge?
There is no fixed limit on the number of files. You can combine two PDFs or dozens at once. The only practical limit is your device's available memory, since the merging is done on your own computer or phone.
Can I choose the order pages appear in the merged PDF?
Yes. Each file in the list has Move up and Move down buttons, so you can set the exact sequence before merging. The final PDF stacks the files top to bottom in the order shown, and you can remove any file before combining.
Do you add a watermark or require me to sign up?
Never. The merged PDF is clean with no watermark, no signup, no email, and no daily task limit. It is completely free to use as often as you want.
Will merging reduce the quality of my PDFs?
No. Pages are copied from your source files into the new document without re-encoding the text, fonts or images, so the merged PDF keeps the original quality of every page.
Why won't one of my files merge?
If a PDF is password-protected, encrypted or corrupted it can't be read in the browser. Remove that file from the list (or unlock it in your PDF reader first) and merge the rest. The tool will tell you which file caused the problem.
Does it work on mobile and all browsers?
Yes. The tool runs in any modern browser on Windows, Mac, Linux, Android and iOS โ no app or extension to install. Drag-and-drop works on desktop, and tapping the drop zone opens your file picker on mobile.
