Combine multiple PDF files into a single document exactly the way you want. Safe, fast, and entirely processed on your device.
You can select multiple files at once
Unlike standard PDF tools that require uploading your sensitive documents to a server, our merger uses WebAssembly to stitch pages together directly on your machine.
Maintain your exact font formatting, embedded images, and page margins. The original document structures remain completely intact during the merging process.
Bypass upload and download waiting times. By utilizing your device's local CPU, multi-megabyte PDF combinations are completed in milliseconds instead of minutes.
Merging your PDF documents is simple. First, drag and drop your target PDF files into the selection zone above, or click to open your file browser. Once your files populate in the list, verify that you have selected all required documents. Finally, click the "Merge PDFs" execution button. Our local script will instantly construct a new sequential PDF document containing all pages from your selections and automatically trigger a secure local download.
