Merge PDF Files Online

Combine two or more PDF files into a single document in seconds — free, unlimited, and 100% private.

Merging PDFs is one of the most common document tasks — combining a signed contract with its appendix, stacking monthly reports into one file, or putting scanned pages back together after they were split apart. This tool lets you merge any number of PDF files (and images) into a single PDF, directly in your browser.

Just add your files, drag them into the order you want using the up and down arrows, and click Create PDF. Because everything runs locally using JavaScript, there's no upload step and no wait for a server to process your files — merging even large PDFs happens almost instantly, and your documents are never seen by anyone but you.

There's no account to create, no page or file-count limit, and no watermark added to your merged PDF. You can also merge JPG and PNG images alongside PDFs — each image becomes its own page in the final document — which is useful when you need to combine a scanned cover sheet with an existing PDF report.

Frequently asked questions

Is merging PDFs really free?

Yes. There's no signup, no watermark, and no limit on how many files or pages you merge.

Are my PDFs uploaded to a server?

No. Merging happens entirely inside your browser using JavaScript. Your files never leave your device.

Will the merged PDF keep the original formatting?

Yes. Pages are copied directly from the source PDFs, so text, images, and layout stay exactly as they were.

Can I control the order of the merged pages?

Yes. Use the up and down arrows next to each file to set the order before merging.
