Merge two or more PDFs into a single document directly in your browser. Files are combined on your device — nothing is uploaded to a server — and pages are copied losslessly, so the merged file looks exactly like the originals.
- Is this PDF merger really free?
- Yes. Every tool on this site is free, with no accounts, no watermarks and no page or file limits.
- Are my files uploaded to a server?
- No. Merging runs entirely in your browser; your PDFs never leave your device. You can verify in your browser’s network tools that no file data is sent anywhere.
- Will merging reduce quality?
- No. Pages are copied into the new file without re-encoding, so text, images and vector graphics stay byte-identical.
- Can I change the order of the files?
- Yes — drag files in the queue to reorder them before merging.
- Is there a size limit?
- There’s no fixed cap. Because everything runs on your device, very large files are limited only by your browser’s memory and may take longer.
