or click to choose · add at least two PDFs to merge
Files never leave your device — conversion runs in your browser
Three steps, a few seconds
Add two or more PDFs
Drag your files in or click to browse. Add as many documents as you need — no file count limit.
Set the order
Use the arrow buttons so documents appear in the combined file exactly how you want them.
Merge and download
Click Merge PDFs and the combined document downloads instantly, complete and watermark-free.
Combine PDF files without handing them to a server
Merging PDFs usually means contracts, invoices, statements, applications — documents you'd rather not copy onto a stranger's server just to staple them together. This merge tool combines your PDFs entirely in your browser: pages are copied from each source file into one new document on your device. No upload, no queue, no deletion promise to take on faith.
Your order, all pages, no limits
Every page of every file is included, in the file order you set with the arrows — first file first. There's no cap on the number of files or their size beyond what your device's memory can hold, and the merged PDF comes out clean: no watermark, no appended advertising page, no "upgrade to keep page order."
Building the PDF from photos first?
If what you're actually combining is pictures — receipts, scanned pages, homework — skip the two-step dance and use the Image to PDF converter to go straight from photos to one ordered PDF. On your phone, the free Photo to PDF app does the same on-device, including a scanner mode that photographs pages straight into a PDF.
Questions about this tool
How do I merge PDF files for free?
Add two or more PDFs above, order them with the arrows, and click Merge PDFs. The combined file downloads instantly — free, no watermark.
Is there a limit on how many PDFs I can merge?
No fixed limit — merge as many as your device's memory comfortably handles. Very large batches just take a little longer.
Can I merge password-protected PDFs?
No — encrypted PDFs can't be read by the merger. Remove the password first, then merge.
Are my documents uploaded during the merge?
No. The merge happens in your browser with the pdf-lib library; your documents never leave your device.
