Merging PDFs is one of the most common document tasks. The problem: most sites require upload. If you handle contracts, payslips or personal records, that is unnecessary risk.
Why merge in the browser
With PDFX, files stay on your device. Select two or more PDFs, set the order and download — no server queue, no daily cap, no sign-up.
Step by step
- Open Merge PDF
- Drag PDFs or click Select files
- Reorder by dragging cards
- Click Merge PDF and download
Tips
- Order matters: the first file becomes the first pages of the output
- Memory: very large PDFs need more RAM — close unused tabs
- Mobile: works on phones; you only need network to load the page once

When to use something else
High-quality OCR on scans or qualified digital signatures may require server-based specialized tools.
