About Merge PDF Free
This free PDF merger lets you combine multiple PDF files into one document online without uploading your files to any server. Select your PDFs, drag to reorder them if needed, and download the merged result. The entire process happens in your browser, which means no file size limits, complete privacy, and no waiting for a server to process your upload.
Merging PDFs is useful when you need to send multiple related documents as a single file - combining a contract with its appendices, assembling a multi-chapter report, packaging a proposal with supporting attachments, or consolidating scanned pages from a multi-page document. Sending one file is always cleaner than sending several.
After uploading, a page preview shows each PDF in sequence. Drag the items to reorder them before merging. If you realize you added the wrong file, remove it and add the correct one - no need to start over. When the order is right, click merge and the combined PDF downloads instantly.
No account is required, there is no file size limit on the client side (though very large files may take a few seconds to process depending on your device), and your documents never leave your browser. The output is a standard PDF compatible with any viewer.
If you need to do the reverse - split a combined PDF into its component pages, or remove specific pages from a document - use the PDF Page Selector tool.
