About this tool
Merging combines several PDFs into a single document in the order you choose — useful for applications (cover letter + CV + certificates), invoices, or scanned documents. This tool uses PDF-Lib in your browser: files are never uploaded, which also makes it faster and private. Add files, arrange the order, merge and download.
FAQ
How many PDFs can I merge?
There is no hard limit — very large combined files may be slower on older phones.
Can I control the page order?
Files merge top-to-bottom in the list. Remove and re-add to change order (drag-to-reorder is coming).
Are my documents uploaded?
No. Merging happens locally with JavaScript — nothing leaves your device.
