Free online PDF merger
PixelTools Merge PDF is a free online tool for combining multiple PDF files into one document. It is useful for joining invoices, contracts, reports, school assignments, scans, forms, receipts, presentations, and other PDF documents before sharing or printing them.
Upload two or more PDF files and arrange them in the order you want. The document at the top becomes the first section of your merged PDF, followed by each file below it.
Your merged PDF is created directly in your browser. Your documents do not need to be uploaded to a PixelTools server, which helps keep private files such as client documents, financial records, and personal paperwork on your device.
The tool copies the original pages into a single PDF instead of converting pages into images. This helps preserve the quality and selectable text of standard PDF documents.
