Frequently Asked Questions

How do I merge PDF files?
Drag and drop your PDF files into the upload area, or click to browse. Reorder them by dragging, then merge to combine and download a single document.
Is my data secure?
Yes. All transfers are encrypted with HTTPS. Your files are automatically deleted within 1 hour and are never stored permanently. We do not read or access your documents.
What are the file limits?
You can merge between 2 and 20 PDF files at once, each up to 25MB. There is no limit on the total number of pages in the merged document.
Do I need to install anything?
No. Everything runs in your browser — no signup, no Adobe, and no software to install.
