Merge PDF Files

Combine multiple PDFs into one document in the order you choose. Free, private, in your browser.

Need a smaller file after merging? Compress PDF. For bulk images and video, download Compresso.

Merge PDF files online — combine multiple documents into one file in the order you choose. This free PDF merger runs fully in your browser on Compresso. Nothing is uploaded to a server.

Accountants stitch invoices and statements; lawyers bundle exhibits; students combine chapter scans into one submission. Merging avoids sending five separate attachments when one file will do.

After you merge, shrink the result with Compress PDF, or protect it with Lock PDF. For bulk image and video folders offline, download Compresso for Mac or Windows.
