A free PDF merger that keeps your files private

DoceasePDF merges PDF files entirely in your browser. Unlike most online PDF combiners, your documents are never uploaded to a server — contracts, invoices and scans stay on your device from start to finish.

There are no limits to how many files you can combine, no watermarks on the result, and no account required. Open the first PDF, merge in the rest, and download one clean document.

Need to trim the combined file? The same tool lets you delete or extract pages, rotate sideways scans, add text and highlight — before you download.
