Free toolBlur Image

Blur images online

Upload an image and choose Light, Medium or Strong, or drag the radius slider, to apply a Gaussian blur to the whole image. The preview is rendered instantly on a smaller copy and matches the final result. Useful for website and slide backgrounds, wallpapers, or blurring an entire screenshot before sharing. To blur just part of an image, such as faces or license plates, use Pixelate Image.

Features

  • Presets plus slider

    The presets are 0.5%, 1.5% and 4% of the long edge, so the effect looks the same on any size; the slider gives exact control.

  • Instant preview

    Pause after changing a setting and the preview appears, made with the same processing as the final download.

  • Clean transparent edges

    Blurring PNGs with transparency leaves no dark fringes around the edges.

Stored temporarily, deleted after 2 hours

Your image is used only for this edit. Originals and results are deleted automatically after 2 hours and download links work only for you. Date taken, camera model and GPS location are removed by default.

FAQ

How do I blur only part of an image?
Use Pixelate Image: draw areas on the image and choose the Blur style. You can do several areas at once.
Can a blurred image be restored?
No. Gaussian blur discards detail, so the downloaded image cannot be turned back into the original.
What does the blur radius mean?
A larger radius means more blur. It is measured in pixels of the original image and defaults to 1% of the long edge.
Can I blur an animated GIF?
Yes, but only the first frame is processed and the result is a still image.
