Free PDF tool
Merge PDF
Combine multiple PDF files into one PDF. The merge happens locally in your browser, so your files are not uploaded to TinyToolbox.
Files are merged in the order selected by your browser. If order matters, select them in sequence or rename them alphabetically first.
Privacy note: PDFs are processed on your device. Password-protected PDFs may not work.
Private PDF merger
Use this tool for receipts, forms, scanned pages, reports, contracts, homework, and small document bundles. It creates one combined PDF without sending files to a server.
Are my PDFs uploaded?
No. The merge runs in your browser using a local PDF library loaded from TinyToolbox assets.
Tips
- Rename files like 01-cover.pdf, 02-form.pdf, 03-receipt.pdf before selecting if you need a clear order.
- Very large PDFs can take longer on phones.
- If a file is encrypted or damaged, try unlocking or re-exporting it first.
