Frequently Asked Questions

A strong blur is effective for casual viewing, but if the information is genuinely sensitive, covering the area or cropping it out entirely is safer. Blur strength varies with resolution and how the image is displayed.
A low to medium setting gives the depth-of-field look that makes text readable over a background. Reserve the heaviest settings for deliberately obscuring something.
No, the output keeps the exact pixel dimensions of the source. Only the sharpness of the detail changes, so the picture will still scale to the same places.
This tool applies the blur across the whole image. For a localised effect, blur the full image and then mask or crop the part you want to keep sharp in an editor.

About Blur Image

Blurring is the fastest way to stop something being the focus of attention without removing it. A blurred background keeps the shape, colour and mood of a scene while pushing the subject forward. Editors blur a bystander in a street shot, designers blur the clutter behind a product, and developers blur a hero background so overlay text stays readable.

It is also the standard way to obscure something sensitive: a face in a crowd, a licence plate, a house number, a screen, a document, or a screenshot of somebody else conversation. A heavy, irreversible blur is a much better answer than hoping nobody zooms in on a small thumbnail.

This tool accepts jpg, jpeg, png and webp uploads of up to 10 MB and applies a Gaussian blur with an adjustable radius. Light settings give a soft depth-of-field look; heavy settings turn the whole image into an unreadable wash. The output stays in the format you uploaded, the resolution is unchanged, and everything happens on the server in a couple of seconds.

When to Use This Tool

  • Blurring a busy background so a headline, logo or product in the foreground reads clearly
  • Obscuring a face, licence plate, house number or screen in a photo before you publish it
  • Softening the background of a portrait to create a depth-of-field effect for a portfolio or a card
  • Blurring parts of a screenshot that contain personal data or a private conversation
