Merge PDFs in your browser (any device)
Open the free Merge PDF tool and add your files.
Use the arrows to put them in order – the first file becomes the first pages.
Click "Merge PDFs". The combined file downloads immediately. Nothing is uploaded, so it is safe for contracts, statements and IDs.
On a Mac with Preview
Open the first PDF in Preview, show thumbnails (View > Thumbnails) and drag the other PDFs into the sidebar. Then choose File > Export as PDF.
Why not just any online PDF merger?
Most popular PDF websites upload your files to their servers and many limit free use. A browser-based tool processes everything locally, which is faster for big files and keeps sensitive documents private.
Frequently asked questions
Can I combine PDFs on my phone?
Yes. The browser tool works on iPhone and Android – tap to choose files from your phone.
Is there a page or size limit?
No fixed limit. Very large files depend on your device memory.
Can I remove pages before merging?
Yes – use Split PDF to extract the pages you want first.
