How many PDFs can I merge at once?: You can merge multiple PDFs with no strict limit. The only limitation is your browser's available memory. Most modern browsers can easily handle merging 10-20 PDFs.
What is the file size limit?: Each PDF file can be up to 100 MB. The merged output size depends on your input files.
Can I change the order of PDFs?: PDFs are merged in the order you upload them. If you need to change the order, you can remove files and add them again in the desired sequence. Position numbers are displayed to help you track the order.
Are my PDFs uploaded to a server?: No! All merging happens directly in your browser using JavaScript. Your PDFs never leave your device, ensuring complete privacy and security.
Will the merged PDF lose quality?: No. The merging process preserves the original quality of all pages. Text, images, and formatting remain exactly as they were in the original PDFs.
Can I merge password-protected PDFs?: Currently, password-protected (encrypted) PDFs cannot be merged. Please remove the password protection first using our Unlock PDF tool.
