Technical Details

If you're curious about how this works, we rely entirely on your device's browser to process the data locally. Whether you are working with JPEG files or PNG files, processing them locally maintains the absolute highest image fidelity possible.

Having Trouble? Try This Workflow

Sometimes, you might want to perform a highly complex task that this specific tool wasn't built for. For example, if you are trying to combine very specific pages from multiple different files, or if you need to isolate certain pages before processing them, the best method is a two-step approach:

  1. Step 1: Isolate your pages. First, navigate to our Split PDF orExtract Pages tool from our homepage. Upload your files there, extract the exact pages you need, and save the resulting files to your computer.
  2. Step 2: Process your pieces. Once you have your isolated, clean PDF pieces, come back to this Blur Image tool (or the Merge PDF tool) and upload your newly extracted files. You will have total control over exactly what gets processed!

100% Secure and Private

We understand that your documents often contain highly sensitive information. That is why the Blur Image tool utilizes cutting-edge client-side processing technology. All the heavy lifting happens entirely on your own device. Your PDF files are never uploaded to our servers, ensuring absolute privacy.
