Frequently asked questions
Are my PDF files uploaded to a server?
No. Merging happens entirely in your browser. Your files never leave your device and are never stored anywhere.
How many PDF files can I merge at once?
There is no fixed limit. Your device's available memory is the limit - a typical computer can handle several hundred pages without issues.
Does merging reduce quality?
No. Pages are kept unchanged. Text stays text, images are not recompressed, and the file size is roughly the sum of the original files.
Does merging cost anything?
No. The tool is free, requires no registration, and adds no watermark.
Does it work on a smartphone?
Yes. The tool works in any modern browser on Android and iOS. Very large files may take a little longer to process on a phone.
