About this tool
Combine multiple PDF files into one. Drag to reorder, no watermark, no signup. Files stay in your browser.
Privacy
Everything runs in your browser using pdf-lib and pdf.js. Your file never touches a server. Open DevTools → Network and you'll see zero traffic from this page.
Tips
- Use Chrome, Edge, or Safari for the best performance.
- For very large files (100+ pages), close other tabs to free RAM.
- Need batch processing? Upgrade to Pro — unlimited files, up to 500MB each.
