Combine multiple PDF files into one — reorder them, then download a single merged document. No upload to any server.
Upload and combine 2 to 50+ PDF files into a single PDF. All pages are preserved in the exact order you specify — drag to reorder files before merging.
Rearrange the order of your PDF files before merging with simple drag-and-drop. See the file names and page counts before committing to the merge order.
PDF merging is performed entirely in your browser. Your documents never leave your device, making it safe to merge confidential contracts, legal documents, and financial reports.
You can merge as many PDF files as your browser's memory can handle. For best performance, keep the total combined size under 100 MB. Very large PDFs (50+ pages each) across many files may take several seconds to process on lower-end devices.
No. The merger combines PDF pages without re-rendering or re-compressing the content. All text, images, fonts, and formatting from each source PDF are preserved exactly in the merged output.
Password-protected PDFs cannot be processed without first removing the password protection, as the browser cannot access encrypted PDF content. Remove password protection using a dedicated tool before merging.
