How to use this tool

Upload your PDFs, arrange them in the correct order, then merge and download the combined PDF.

The tool copies pages from each input PDF into a new PDF document entirely client-side, then generates a download.

No file uploads. Your PDFs are processed locally in your browser memory.

Can I reorder PDFs before merging?

Yes — use the up/down buttons to change the merge order.

Is there a file size limit?

Limits depend on your device and browser memory. Very large PDFs may be slow.

Extract a page range or split a PDF into single-page files.

Optimize a PDF by re-saving and optionally stripping metadata (client-side).

All processing happens inside your browser. No files or data are uploaded to our servers, ensuring your privacy is strongly protected.

Built with Next.js and Tailwind CSS. The site is fully client-side and open source.
