Frequently Asked Questions
Quick direct-answer guides about using this utility tool locally and securely.
Is there a limit on the number of PDFs I can merge?
No. Since the merging process is run 100% locally in your browser memory, there are no artificial file upload limits. You can combine as many files as your device RAM can handle.
Will my merged PDFs have watermarks?
No. All tools in PDF Tools are completely free and do not add any watermarks or branding to your documents.
Is it safe to merge sensitive files like contracts or bank statements?
Absolutely. Your files never leave your computer. The combining engine runs entirely client-side using Javascript, meaning your sensitive documents are 100% private.
