Private Client-Side PDF Merging

Combining contracts, bank statements, medical records, or tax returns using remote PDF websites exposes sensitive personal identity information to third parties.

  1. Select or drag-and-drop two or more PDF files from your device.
  2. Arrange files in your desired reading order.
  3. Click Merge PDFs to compile and download your combined document instantly.

Frequently Asked Questions

Are my PDF files uploaded to an online server during merging?

No. ToolMint processes PDF byte streams 100% inside your browser memory using WebAssembly. Your files are never sent over the internet.

Is there a limit on how many PDF files I can merge?

Because processing runs on your device, there are no artificial file size or page count limitations beyond your device's available memory.
