Frequently Asked Questions

Can I blur just one face in a photo without blurring everything?

Yes. Use the region-select feature to draw a box over the face you want to blur. The rest of the image stays sharp, letting you obscure specific people or details while keeping the rest of the photo clear.

What is the difference between Gaussian blur and pixelate?

Gaussian blur creates a smooth, gradual softening effect — like an out-of-focus lens. Pixelate breaks the area into large colored squares (a mosaic), which is often used for censoring faces in news or social media.

Can a blurred image be 'unblurred' to reveal the original?

Gaussian and pixelate blur applied at high intensity is not reversible by normal means. However, for sensitive data like credit card numbers, use a high pixelate or opaque box rather than a low-intensity blur.

Is this tool useful for photography, or just privacy?

Both. A subtle background blur adds a shallow depth-of-field effect to portraits. Motion blur can make a still photo look dynamic. Strong Gaussian blur over the whole image creates a dreamy, artistic look.

Does blurring change the file size?

Blurring smooth areas can slightly reduce JPG file size because blurred regions compress more efficiently. The change is usually small unless you blur the entire image heavily.
