Blur & Pixelate — FAQ
Upload your photo, brush over the faces or areas you want hidden, and download the result.
Yes, free forever with no signup and no watermarks.
Yes. Brush over any area — faces, plates, or text — and it is blurred the same way.
No. Once you download the blurred image, the hidden details are permanently covered.
No. Blurring happens in your browser, so your photos never leave your device.
Blur smooths details into a soft haze, while pixelate turns the image into visible mosaic blocks. For faces, license plates and sensitive text, pixelation usually hides more, because edges and letters break apart completely. Both effects apply across the whole image, and the intensity slider from 1 to 100 controls their strength.
Yes — A strongly blurred photo creates a calm background that keeps headlines and quotes easy to read on top. The same look works for preview thumbnails and privacy-safe teasers, where the mood stays visible but details stay hidden. Choose a high intensity so the background never fights with your text.
Raise the intensity first, because a light blur often only softens small text instead of hiding it. If details still show, switch to pixelate, whose mosaic blocks break up letters and faces far more reliably. Always check the downloaded image at full size, since saved blur cannot be undone.
The scale runs from 1 to 100, where low values smooth gently and high values hide almost everything. Start in the middle and increase until you reach the protection you need, without destroying more of the picture than necessary. Note the value down so other images in the same set match.
This tool applies the effect to the whole image. To hide just one region, crop that area first, apply blur or pixelate to the crop, and then use it in your design if needed. Never share the unprotected version publicly, because the blurred copy only protects you if it is the one being shared.
