Merge PDFs without uploading files
This tool loads PDF files in your browser, copies their pages into a new PDF, and gives you a local download.
Private by design
The merge runs on your device, so your PDFs do not need to leave your browser.
FAQ
Are my PDF files uploaded?
No. The files are read and merged in your browser. ToolsLab does not receive the PDF files.
Can I reorder files before merging?
Yes. Use the arrow buttons beside each file to choose the order before creating the merged PDF.
Will every PDF work?
Most ordinary PDFs work. Password-protected, damaged, or heavily signed PDFs may fail or lose signature validity after merging.
