Frequently Asked Questions about PDF Merging

Is this PDF Merge Tool free?
Yes, our online PDF merge tool is absolutely free. You can merge any number of files without registration or hidden costs.
Is the online tool safe and private?
Absolutely. The entire process of merging the PDF documents happens directly in your browser (client-side). Your files are never uploaded to a server, ensuring maximum security and data privacy.
Is there a limit on the number or size of files?
Technically, there is no set limit. However, since the processing takes place on your device, performance depends directly on your computer’s processing power. We recommend not processing more than 50 very large PDFs at once.
How do I rearrange the order of the PDF documents?
Once your files are uploaded, you can easily click and drag & drop the individual document names in the “Document Order” list. Simply drop the file where you want it to appear in the final merged PDF.
Does combining PDFs affect the original file quality or resolution?
No, the merging process simply copies the existing pages into a new document. The quality, resolution, and formatting of the pages themselves are preserved from the original files. Your resulting PDF document will maintain the clarity of the source files.
Can I use this PDF Combine tool on my phone, tablet, or Mac?
Yes! Since this is a browser-based tool, it works great on any device with a modern web browser, including mobile phones, tablets, laptops, and all operating systems like Windows, macOS, and Linux.
