Is merging PDFs free?

Yes. Merging is completely free with no page limits, no sign-up and no watermark on the output.

Are my files uploaded to a server?

No. The merge happens entirely in your browser using your device's own processing, so your documents stay private.

How many PDFs can I combine at once?

You can merge as many files as your device's memory allows. For very large jobs, merge in smaller batches for the best performance.

Will the quality or formatting change?

No. Pages are copied exactly as they are, so text stays sharp and selectable and the layout is preserved.

Can I change the order of the files?

Yes. Drag any file up or down in the list before merging to control the final page order.

Merging PDFs is the fastest way to turn scattered files — invoices, scans, chapters, signed contracts — into one document that is easy to share and print. This tool combines any number of PDFs into a single file and lets you set the exact page order before you download.

Everything runs locally in your browser, so your files never leave your device. There is nothing to install, no account to create, and no watermark added to the result.
