How to work with PDFs using PDF Tools

PDF Tools is a set of 11 free PDF tools that run 100% in your browser. There are no uploads, no accounts, and no servers involved — your files are processed on your own device.

The 11 tools

• Merge — combine several PDFs into one document.
• Split — break one PDF into separate files.
• Compress — shrink a PDF’s file size.
• JPG to PDF — turn JPG images into a PDF.
• PDF to JPG — turn PDF pages into JPG images.
• Rotate — rotate pages that are sideways or upside down.
• Organize — reorder, add, or remove pages.
• Watermark — stamp text across your pages.
• Page Numbers — add page numbers to a document.
• Unlock — remove a PDF’s password protection.
• Protect — add a password to a PDF.

Which tool do I need?

• Several files into one document → Merge.
• One file into several documents → Split.
• A file that is too big to send → Compress.
• Photos that need to become a document → JPG to PDF.
• Pages you want as images → PDF to JPG.
• Pages in the wrong orientation → Rotate.
• Pages in the wrong order, or pages to drop → Organize.
• Text stamped across pages → Watermark.
• Numbers on every page → Page Numbers.
• A password to remove → Unlock.
• A password to add → Protect.

Use any tool

The flow is the same for every tool:

1. Open PDF Tools and pick the tool you need from the grid.
2. Add your file or files to the tool.
3. Adjust the tool’s options for what you want to do.
4. Process the file and download the result.

Heavy files are handled in background workers, so the page stays responsive while processing runs.

Tips

• Do conversions before edits. If you need a JPG as part of an edited PDF, convert it to PDF first, then use Merge or Organize on the result — each tool does one job, and chaining them in order is the simplest path.
• Check page order after organizing. After reordering or removing pages, glance through the result before downloading — it is quicker to fix the order now than to re-run the tool.
• Keep a copy of the original. Tools like Compress, Unlock, and Protect change the file itself. Download the result as a new file and keep your original untouched, in case you need it again.
• Your files never leave the device. Because everything runs in the browser, you can use these tools for sensitive documents without sending them to any server.
