Frequently Asked Questions (FAQ)

Is it safe to merge PDFs online?

Yes! When you use MergeMaster, it is completely safe. This is because our tool processes your files locally within your browser. We never upload your PDFs to our servers, meaning your sensitive data is never exposed or stored.

Is there a limit to how many files I can merge?

Our tool can handle a large number of files, limited only by your browser's memory capacity. For most standard documents, you can comfortably merge dozens of files at once.

Will merging PDFs reduce the file quality?

No. Merging PDFs simply appends the pages of the selected documents together. The internal structure, text quality, and image resolution of the original files are fully preserved in the merged document.

Can I merge PDFs on my mobile phone?

Absolutely! Our website is fully responsive and works perfectly on mobile browsers (iOS and Android). You can select PDFs from your phone's storage and merge them just as easily as on a desktop computer.
