FAQ
Frequently asked questions
Are my PDF files uploaded?
No. Your PDFs are processed entirely in your browser. They are never uploaded to a server, never stored, and never visible to anyone but you.
Can I merge PDF documents for free?
Yes. This PDF merger is completely free and does not require an account or sign-up. There are no hidden fees or usage limits.
Will the merged PDF have a watermark?
No. The merged PDF is clean — no watermarks, no logos, no branding are added to your file.
How to merge PDF files?
Add your PDF files, place them in the order you want, then select Merge PDF. The merged file is created in your browser and downloaded as merged.pdf.
How to merge multiple PDF files into one?
Select two or more PDFs at once, or drag them all into the tool at the same time. You can reorder the files before merging them into a single PDF.
Can I merge two PDF files?
Yes. Add both PDFs, confirm the order, and merge them into one downloadable file in seconds.
Can I reorder PDF files before merging?
Yes. Drag files into a new order or use the up and down controls before you merge them.
Does the PDF merger work on mobile?
Yes. The tool runs in your mobile browser on both iPhone and Android. Add PDFs from your phone, arrange the order, and merge — no app install required.
Can I merge PDFs without an internet connection?
Once the page has loaded, merging works entirely offline. Your PDFs stay in your browser memory, so you can combine files even without an internet connection.
What browsers are supported?
The merger works in all modern browsers including Chrome, Firefox, Safari, and Edge. For the best performance with large files, use the latest version of your browser.
Do I need Adobe Acrobat to merge PDF files?
No. You can merge PDF files directly in this browser tool without installing Adobe Acrobat or any other software.
Can I merge password-protected PDFs?
Password-protected PDFs are not supported. Unlock them first, then add the unlocked files to merge.
Will merging affect digital signatures?
Merging signed PDFs can invalidate digital signatures. Use the original signed files when signature validity matters.
Is there a file size limit?
There is no server upload limit because files stay in your browser. Inputs up to 100 MB have been tested in-browser, but very large PDFs may still be limited by your device memory.
