Frequently Asked Questions
Is this PDF merger really free?
Yes. This online PDF merger is free to use, with no signup, no subscription, and no watermark added to your merged file.
Is it safe to merge my PDF files online?
Yes. Your PDFs are merged directly in your browser on your own device. The files are never uploaded to our servers, so they never leave your device.
How many PDF files can I merge at once?
You need at least two files, and there is no fixed maximum. Very large batches depend on your device’s available memory, so for dozens of big files you may merge in smaller groups.
Is there a file size limit?
We do not set a fixed file size limit. Because merging happens in your browser, the practical limit depends on your device’s memory and performance.
Can I change the order of the files before merging?
Yes. Use the up and down arrows next to each file to arrange them, and the merged PDF will follow that order.
Will merging reduce the quality of my PDFs?
No. Pages are copied into the new document as they are, without recompression, so text, images, and layout keep their original quality.
