Frequently Asked Questions
What is the difference between Gaussian and Pixelate blur? +
Gaussian blur creates a smooth, soft blur effect — good for background blurring. Pixelate creates a blocky mosaic effect, which is better for hiding faces, license plates, text, or any private information in a recognizable way.
Can I blur just part of an image? +
Yes. Switch to Area Blur mode, then click and drag on the image to draw rectangles over the areas you want to blur. You can add multiple blur areas and remove individual ones.
Will the original image quality be preserved outside blur areas? +
Yes. Only the selected areas are blurred. The rest of the image remains at full original quality.
What image formats are supported? +
JPG, PNG, WebP, and BMP are all supported. The output is always saved as a PNG to preserve quality for area blurring.
Are my images sent to a server? +
