Common questions
Are my files uploaded to the internet?
No. This tool runs entirely in your browser: the document is opened on your device, processed there, and never sent anywhere. You can even go offline once the page has loaded.
Can I merge PDFs of different sizes or orientations?
Yes. Each page keeps its original size and orientation — an A4 portrait and an A3 landscape sit in the same file without being resized.
Is it free, and do I need an account?
Free and unlimited, with no account and no sign-up. This tool costs us nothing because it runs on your machine, so we have no reason to ration it.
