Combine multiple PDF files into a single document in seconds. Drag and drop to reorder, preview each file before merging, and download the result instantly. Everything happens in your browser — no uploads, no sign-up, no watermarks.
The order in the file list is the order in the final PDF. Drag the grip handle on the left of each card to move it up or down. This is the most common cause of mis-merged outputs — double-check the order before you click MERGE.
You can merge PDFs with different page sizes (A4, Letter, Legal, custom) into one document — each page keeps its own dimensions. If you need a uniform size across the merged file, run it through Compress PDF or rebuild via Image to PDF.
Scanned PDFs are image-based, while digital PDFs contain selectable text. Merging them works fine, but the resulting file will be larger because of the scans. Use Compress PDF afterwards to bring the size down.
Password-protected PDFs can't be merged directly — you'll need to remove the password first using a desktop tool. This is a security limitation of the browser's PDF parsing, not the merge tool itself.
All merging happens in your browser. PDFs never get uploaded to any server, no copies are stored, and no account is required. Closing the tab discards everything from memory.
Merge as many files as you need, as often as you need, with zero limits and no watermark on the output. The tool is free for both casual and professional use.
