PDF Merge (Combine PDFs)

Merge PDF files online securely and privately

Our PDF Merge tool allows you to combine multiple PDF documents into a single, well-organized file directly in your browser. Whether you need to merge reports, invoices, assignments, contracts, or scanned documents, this tool makes the process fast, simple, and completely secure. Unlike many online services, your files are never uploaded to any server. Everything is processed locally on your device, ensuring full privacy.

Why merge PDF files?

Combining PDF documents helps keep your files organized and easier to manage. Instead of sharing multiple files, you can create one clean document that is simple to send, store, and print. This is especially useful for students submitting assignments, professionals sharing reports, and anyone handling digital paperwork.

Merging PDFs helps reduce document clutter, keeps pages in the correct order, and improves readability when sharing or printing files.

100% private and secure processing

Your privacy is our top priority. This tool uses modern browser technology and the powerful pdf-lib library to merge files directly on your device. This means your documents never leave your computer. There are no uploads, no tracking, and no risk of your files being stored online.

Reorder pages exactly the way you want

After adding your PDF files, you can rearrange them using simple controls to achieve the perfect order. Whether you want chronological arrangement, chapter sequencing, or custom document structuring, you remain in full control of the final output.

Fast, simple, and unlimited

The merging process happens instantly inside your browser. There are no file size limits, no watermarks added to your document, and no sign-up requirements. Simply add your PDFs, arrange them if needed, click merge, and download your combined document within seconds.

Perfect for everyday use

This PDF combiner is ideal for merging scanned documents, combining ebook chapters, assembling business reports, joining invoices and receipts, and organizing study notes or project files into a single document.
