Merge to PDF
Combine PDFs and images into one PDF, in order.
Your merged PDF appears here
Add PDF files and images, drag them into order, then Merge. Every file is read in your browser and combined into a single PDF you can download — your originals never leave your device.
Runs entirely in your browserMerge PDFs and images into one PDF, locally
Drop in any mix of PDF files and images — JPG, PNG, or WebP — arrange them in the order you want, and this tool stitches them into a single PDF. Each PDF's pages are appended in place and each image becomes its own page. You can keep every page at its original size or fit everything to a standard A4 or US Letter sheet. Your files are read and combined entirely in your browser and are never uploaded to any server.
Common questions
How do I merge PDF files into one?
Drop your PDFs here, drag them into the order you want with the arrows, and click Merge. The pages of every PDF are appended in that order into one new PDF you download — all in your browser, with no account.
Can I combine images and PDFs together?
Yes. Add any mix of PDF, JPG, PNG, and WebP files. Each image becomes one page and each PDF contributes all of its pages, in the order you arrange them.
Can I change the order of the files?
Yes. Use the up and down arrows on each file in the list to move it earlier or later. The final PDF follows the order shown top to bottom.
What does the page size option do?
“Keep original size” preserves each PDF page and sizes image pages to the image. “Fit to A4” or “Fit to Letter” scales every page onto that standard sheet with a small margin, which is handy when you plan to print.
Are my files uploaded anywhere?
No. Everything happens in your browser tab using the pdf-lib library loaded on your device. Your files are read locally and the merged PDF is built on your machine — nothing is sent to a server.
