Frequently Asked Questions
Is the PDF merge process secure?
Yes. The PDF merge process happens entirely in your browser. Your files are never sent to any server — all processing occurs on your device. This ensures your sensitive documents stay completely private.
How many PDF files can I merge?
You can merge an unlimited number of PDF files. However, depending on your browser's memory capacity, very large files may cause performance slowdowns. Generally, files under 50 MB work without issues.
How do I set the order of the merged PDFs?
After uploading, you can drag and drop files in the list to rearrange their order. The merge process follows the order in the list — pages from the first file come first, followed by subsequent files.
Can PDFs with different sizes and orientations be merged?
Yes. PDF files with different page sizes (A4, Letter, etc.) and orientations (portrait/landscape) can be merged seamlessly. Each page retains its original size and orientation.
Can I merge PDFs without an internet connection?
After the initial page load, the PDF library is downloaded to your browser. From that point on, you can merge PDFs without an internet connection. All operations are performed entirely locally on your device.
