Merge PDF
Combine multiple PDF files into one document online
Frequently Asked Questions
How do I merge PDF files?▼
Click 'Upload' to select multiple PDF files, arrange them in the order you want, then click 'Merge' to combine them into a single PDF document.
Is there a file size limit?▼
Since processing happens in your browser, very large files (100MB+) may be slow. For typical documents under 50MB, merging is fast and reliable.
Are my PDFs uploaded to a server?▼
No — merging uses the pdf-lib library running entirely in your browser. Your files never leave your device.
