Is there a limit to how many PDFs I can merge?

You can merge dozens of files simultaneously depending on your device's memory. All processing takes place locally on your computer.

Can I reorder individual pages between documents?

Yes! You can reorder files in the merge tool, or use our dedicated PDF Pages organizer to freely move individual pages across documents.

Follow these simple steps to process your document with maximum privacy and speed:

Select or drag multiple PDF files into the merger dropzone.

Drag and drop or use arrow buttons to arrange documents in your desired sequence.

Click 'Merge PDFs' to combine all pages into one document.

Download your combined PDF file instantly.

Your file is never uploaded to remote servers. The algorithm runs locally in your browser memory via WebAssembly.

Skip long server queues and network bottlenecks. Documents are rendered and transformed at client-side hardware speeds.

Works seamlessly on Google Chrome, Apple Safari, Firefox, and Microsoft Edge across Windows, macOS, Linux, and iOS.
