Frequently Asked Questions
How does PDF merging work?
Our tool combines multiple PDF files into a single document by extracting pages from each file and adding them sequentially to a new PDF. The original formatting, images, and text are preserved.
Is there a limit to how many PDFs I can merge?
There's no hard limit on the number of files. However, each file can be up to 50MB, and very large merged documents may take longer to process depending on your device.
Can I change the order of PDFs before merging?
Yes! Use the up/down arrows next to each file to reorder them. The files will be merged in the order shown in the list.
Are my files secure?
Absolutely. All PDF processing happens directly in your browser using JavaScript. Your files are never uploaded to any server, ensuring complete privacy.
Can I merge password-protected PDFs?
Currently, password-protected PDFs cannot be merged directly. You'll need to remove the password protection first using a PDF editor before merging.
