Merge PDF Files — Without Uploading Them
Combine multiple PDFs into one document, reorder them first, and download. Unlike upload-based tools, your files stay on your device.
▶ Merge PDF files — free, no upload
Why local merging matters- Contracts and financial documents shouldn't ride to a stranger's server just to be stapled together
- No file-size upload limits — a 200MB scan merges as fast as your machine allows
- No watermark, no '2 free tasks per day' meter
How to do it- Open PDFBox — the right tab is already selected
- Add two or more PDFs
- Drag them into the right order with the ↑↓ buttons
- Click the action button and download the result. Done.
Privacy- Your files never upload — everything runs in your browser (pdf-lib + WebAssembly-free JS)
- Nothing is stored; close the tab and it's gone
- Safe for contracts, invoices and anything confidential
