Browser-based PDF tools

Merge PDF Online

Combine multiple PDF files into one document. Files stay in your browser.

PDF Workspace

Files are processed in your browser. Nothing is uploaded.

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.

Best for everyday files

Use it for reports, receipts, forms, and school or work documents that need to become one PDF.

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.
