Blur or Pixelate Image — Free, No Sign-Up
Choose one image, pick Blur or Pixelate, move the strength slider, and press Apply.
Honest note: the effect applies to the whole image, evenly. This tool does not detect faces or select one area — to hide one part only, crop the photo first.
How to use Blur or Pixelate Image
Choose your image
Click the box above or drop one image onto it. The photo appears below with a live preview.
Pick an effect and a strength
Choose Blur to soften the whole photo, or Pixelate to turn it into chunky blocks. Move the strength slider — the preview updates live.
Download the result
Press “Download Image” when it looks right. The effect is baked into the saved image.
Example: Example: pixelate a photo at block size 16 and a number plate becomes unreadable blocks — the rest of the photo is untouched, because the whole image is pixelated evenly.
About Blur or Pixelate Image
Sometimes a photo needs softening: a blurry background look, or hiding a face, a number plate, an address or a name before sharing. ImageTools blurs or pixelates your image right in your browser: pick the effect, slide the strength, and watch the live preview until it looks right. Blur softens everything smoothly; pixelation turns the picture into chunky blocks that hide detail completely.
One honest note: this tool applies the effect to the whole image, evenly. It does not detect faces or pick out one area for you — if you only want one part hidden, crop the photo first, or blur the whole picture. There is no upload, so your pictures never leave your device, and there is no watermark, no limit and no account. Everything is free, and it works on phones, tablets and computers.
Frequently asked questions
How do I blur an image online?
Choose your image, pick Blur, move the strength slider until the preview looks right, and press “Download Image”.
How do I pixelate a face in a photo?
This tool pixelates the whole image evenly. For one face, crop the photo to just that part first, or use a strong pixelation on the whole picture — the face becomes unreadable blocks.
What is the difference between blur and pixelate?
Blur softens the image smoothly, like an out-of-focus photo. Pixelate turns it into chunky square blocks — much better for hiding text, faces and number plates.
Will blurring reduce the image quality?
Blur and pixelate change the picture on purpose — that is the effect. The size in pixels stays the same; only the detail changes.
Is blurring images free?
Yes. Blurring and pixelating images on ImageTools is 100% free. There is no paid plan, no limit and no watermark.
Do my images get uploaded?
No. The effect is applied entirely in your browser. Your images never leave your device and nothing is stored on any server.
