Multiple PDF files — merged in order listed
The Merge PDF tool combines multiple PDF files into a single document, all in your browser. Upload your PDFs in the order you want them merged, click Merge, and download the combined file — no uploads, no server, 100% private.
Zero server lag. All conversions run locally on your device for maximum speed.
Your files never leave your device. No uploads, no servers, no tracking.
You can merge as many PDFs as your browser memory allows. There's no hard limit.
No. Password-protected PDFs need to be unlocked first before they can be merged.
Yes. All merging happens locally in your browser using PDF-lib. No files are uploaded to any server.
No strict limits, but very large files may take longer to process depending on your browser's available memory.
