Sellers sometimes need to obscure a face, house number, packaging barcode, or on-screen chat before posting a product video still or support screenshot. Phone apps bury blur behind subscriptions; desktop editors are slow for a one-off task. Image Blur applies a full-frame Gaussian-style blur controlled by a single slider (1–25px), previewed live, then saved as PNG — all in the browser. It does not include brush-based selective blur or object detection; for partial blur, crop first or use a dedicated editor. Use it when privacy matters more than keeping the background sharp.

How to use Image Blur

  1. Step 1: Upload an image using the drop zone.
  2. Step 2: Adjust the Blur slider (1–25) to control how strong the blur effect is.
  3. Step 3: Preview updates live. Click Download to save the blurred image as PNG.

Practical tips

Frequently asked questions

What does Image Blur do?

Image Blur is a free browser tool that softens an entire image by a chosen intensity. People use it to anonymize screenshots before sharing them with customers or teammates, to mute busy backgrounds for mockups, or to create a soft creative look. You upload a common image format, move the blur slider, watch the preview, and download. There is no account requirement and no claim that images leave your device for server processing.

Can I blur only a face or license plate?

Not with this tool’s current UI. The slider blurs the whole image. For selective privacy edits, crop the sensitive area separately, use a mobile app with a brush blur, or a desktop editor with masks — then return here if you need a uniform soft effect.

Is Image Blur free?

Yes. No signup, no watermark. Strength is limited to the 1–25 range exposed on the page.

What format do I get?

Downloads are PNG after processing so the blurred result preserves detail transitions cleanly. Convert to JPG afterward with our PNG to JPG tool if a marketplace rejects PNG.
