Frequently Asked Questions
How do I merge PDF files for free?+
Upload your PDF files, arrange them in the order you want, then click Merge. The merged file downloads immediately.
How many PDF files can I merge?+
There is no fixed limit. Processing happens locally in your browser, but too many files or very large files may be limited by your device's memory.
Are my files uploaded to a server?+
No. The entire merge process runs in your browser using pdf-lib, and your files never leave your device.
