Why It Matters
One File Is Easier Than Five
Scattered PDFs — a scanned ID here, an invoice there, a signed contract somewhere else — are easy to lose track of and awkward to send. Combining related documents into a single PDF makes them easier to share, store, and review in the right order.
This tool merges entirely in your browser, so nothing is uploaded anywhere. Add your files, drag them into the order you want, and download the combined PDF.
FAQ
Questions About This Tool
No. Merging happens entirely in your browser using pdf-lib — your files are never uploaded, stored, or sent anywhere.
No artificial limit. Since everything runs on your own device, you can merge as many PDFs as your browser can comfortably handle — very large batches on an older phone may just take a little longer.
Yes. Drag any file up or down in the list to change the order pages will appear in the final merged PDF.
No. Pages are copied directly, so text, images, and formatting stay exactly as they were in the original files.
