Frequently Asked Questions
How many PDF files can I merge at once?
You can merge up to 50 PDF files in a single pass and reorder them before combining.
Will merging change the quality of my PDF pages?
No. Pages are copied into the combined document without re-encoding, so text stays selectable and images keep their original quality.
Are my files uploaded to a server?
No. PDFMiniFly processes everything locally inside your browser. Your document never leaves your device, and once the app is installed it also works offline.
