Frequently Asked Questions
Is there a limit to how many PDFs I can merge?
No hard limit. The tool handles as many files as your browser can manage. For most devices, merging 20-30 PDFs works smoothly. Very large batches may take a bit longer.
Does merging reduce PDF quality?
No. Merging combines pages as-is without re-encoding images or text. Your content stays exactly the same quality.
Can I reorder files before merging?
Yes. After uploading, drag and drop the files into the order you want. The final PDF will follow that exact sequence.
Are my files uploaded to a server?
No. All processing happens directly in your browser. Your PDF files never leave your device.
Can I merge password-protected PDFs?
Not directly. You need to unlock the PDF first using our Unlock PDF tool, then merge the unlocked files.
