Blur Image

The tool has two blur types, and each gives a different look:

• Gaussian blur spreads every pixel evenly in all directions. It gives the soft, out-of-focus look you see in background photos and frosted-glass designs. Low values (1 to 4 px) take the edge off; higher values turn shapes into smooth color fields.
• Motion blur layers several faint, shifted copies of the image along one direction, giving a streaked look that suggests movement. Set the direction slider to match it: 0° streaks horizontally, 90° vertically, and anything in between gives a diagonal. The effect is lighter than a Gaussian blur at the same setting and shows best on smaller images.

The preview updates as soon as you move a slider, so you can try both types and several strengths before you download. Switching type keeps your intensity setting.

Blur works on any photo, but the effect is easiest to judge on the full-size download rather than the scaled preview. If you plan to use the result at a small size, such as a thumbnail, remember that shrinking an image also makes the blur look weaker.

The intensity is measured in pixels of the original image, and the blur is applied at full resolution. That matters: a 10 px blur looks strong on a small 800-pixel image but much subtler on a 4000-pixel phone photo, even if the on-screen preview is scaled down.

• For a heavier blur on a large photo, first make it smaller with the image resizer (for example to 1200 pixels wide), then blur it. You will get a stronger effect and a lighter file.
• For a background behind text, a Gaussian blur of 8 to 15 px on a web-sized image usually works well.
• For motion effects, start near the top of the slider, since motion blur is subtler, and adjust the direction to follow your subject.

The downloaded file keeps your original name with _blurred added. If it is larger than you need, run it through Compress Image.

Gaussian blur also softens noise and grain, so a light 1 to 3 px blur can make a grainy low-light photo look smoother when it is used small, for example as a background tile. It will not recover detail, though; for a photo that needs to look sharper, try the AI Image Upscaler.

People often blur screenshots to hide names, faces or account numbers before sharing. This tool applies the blur to the entire image, so it is not designed to hide just one area while keeping the rest sharp. For that kind of redaction, crop the sensitive part out with Crop Image or cover it with a solid box in an image editor. A solid cover is more reliable than a light blur, which can leave text readable.

If you want to mark photos as yours rather than hide details, stamp them with the free Watermark Maker.

Blurring can also help when a photo is too busy to sit behind text. A lightly blurred background photo keeps its colors and mood but stops competing with your headline, which is why it is popular for slide backgrounds, quote graphics and event banners. For the colors of the photo as HEX codes, use Color Palette From Image to match your text to the picture.

Everything runs in your browser using the canvas, so nothing is uploaded and there is no size limit set by RegiAI. Very large images may take a moment longer to update the preview on older phones.
