Merge PDF - 100% Free Online Tool

Yes, completely free! No hidden costs, watermarks, or registration required. Our Merge PDF tool is 100% free with no limitations on the number of files you can process or the size of your documents (up to 50MB per file). We believe powerful PDF tools should be accessible to everyone.

Military-grade security: Your files are encrypted with 256-bit SSL during transfer and automatically deleted from our servers after 1 hour. We never store your processed files, and all processing happens in isolated, secure environments.

Maximum flexibility: We support files up to 50MB each. For larger files, use our Compress PDF tool first to reduce file size.

Fully responsive design: Our tools work perfectly on all devices - desktop, tablet, and mobile. No app download required! The interface automatically adjusts to your screen size, and touch-friendly controls make it easy to upload and process files from any device.

Unlimited merging: You can merge as many PDF files as you need in a single operation. There's no limit to the number of documents you can combine, though each individual file must be under 50MB. You can organize the merge order by simply dragging files into your preferred sequence before processing. This is perfect for creating comprehensive reports, compiling portfolios, or organizing multi-chapter documents where maintaining the correct page order is essential.

Format preservation: Yes, absolutely! Your merged PDF will retain all original formatting including fonts, images, hyperlinks, and layout. The tool uses advanced PDF processing technology that preserves the exact visual appearance of each source document.
