Blur image details for privacy
Choose Brush areas to soften faces, license plates, fields on an ID, or names and messages in a screenshot. Cover the entire detail and check the exported PNG before sharing. For stronger face obscuring, pixelate a face with coarse blocks.
Blur a background or add motion
Brush Soft blur onto the background and leave your subject sharp. Use a smaller brush around its edges. For a sense of speed, select Motion blur and align the angle with the direction of travel.
How to blur a photo
- Choose, drag, or paste an image into the editor. A soft blur appears immediately.
- Pick Soft blur or Motion blur. Apply it to the entire image or brush over individual areas.
- Adjust the strength, compare your edit with the original, and download the blurred PNG.
Blur vs. pixelation
Use soft blur for a smooth background or to draw attention away from a detail. If you need to obscure identifying features before casual sharing, use a coarse mosaic. Large blocks replace groups of pixels with a single color, discarding more fine detail than a light blur and making it harder to reconstruct. Set the block size in the photo pixelator.
Text can sometimes be inferred from either blur or pixelation. For passwords, ID numbers, or confidential records, use an opaque cover or remove the underlying content before sharing. The document image redaction page explains when a mosaic is suitable and when you need permanent redaction.
Frequently asked questions
Is this blur photo editor free to use?
Yes. Open a JPG, PNG, or WebP up to 10 MB and download a PNG for free. The editor runs in your browser, so your original stays on your device. There is no app to install, account to create, or watermark on the result.
How do I blur a picture without blurring the whole image?
Choose Brush areas and paint over the details you want to soften. Adjust the brush size before painting and the blur strength at any time. Use Undo stroke if you paint over the wrong area.
Can I add a motion blur photo effect at an angle?
Yes. Select Motion blur and set the angle to follow the direction of movement. Use Entire image for a full-frame streak or Brush areas to apply it only where you paint.
