Frequently asked questions
Is there a limit on how many PDFs I can merge?
No fixed limit — add as many files as your browser and device memory can comfortably handle. Very large batches (hundreds of big files) may slow down on older devices, since everything is processed locally.
Will merging affect the quality of my PDFs?
No. Pages are copied as-is, so text, images and formatting come through exactly as in the originals.
Can I merge password-protected PDFs?
Not directly. Remove the password from the PDF first (in the app you used to protect it), then merge it here.
Do you keep a copy of my files?
No. Files are read and processed in your browser’s memory and are never sent anywhere. Close the tab and they’re gone.
