About this tool
Merging PDFs is one of those small tasks that shows up constantly and never has a convenient answer built into your computer. You scan a contract in three passes and end up with three files. You collect invoices from a whole quarter and need to send one attachment. A university application asks for a single document containing your transcript, ID and cover letter. This tool joins them in the order you choose and gives you one clean PDF back. Everything happens inside your browser using JavaScript, so the files themselves never travel to a server, which matters when the documents contain bank statements, medical records or signed agreements. There is no page limit, no watermark stamped across your work, and no account to create before you can use it.
Frequently Asked Questions
Is there a limit on how many PDFs I can merge?
+
No fixed limit. The practical ceiling is your device's memory, since the merge happens locally in your browser. Most people combine anywhere from two to fifty files without any trouble.
Are my files uploaded anywhere?
+
No. The merge runs entirely in your browser. Your PDFs are never sent to a server, so nothing is stored, logged or shared.
Can I change the order of the pages?
+
You can reorder the files before merging. If you need to remove specific pages afterwards, use the Delete Pages from PDF Online tool.
Will the quality of the pages change?
+
No. Pages are copied across exactly as they are, so text stays selectable and images keep their original resolution.
