When to pixelate a photo
Use this when a face, a plate, a screen, or a whole picture should break into visible squares. The pixels stay the same size. Only the detail changes.
The slider sets how big each block is. Zero leaves the picture as it is, apart from the format you save. A high setting can turn a portrait into a few dozen squares. Stop when the part you wanted to hide is no longer readable.
This changes the whole photo. It does not paint a soft circle, and it does not cut the frame. If you want a soft look instead of squares, use blur. If you only need one part of the picture, use crop first.
JPG cannot store a clear background. If the source has empty pixels, a JPG fills them with white when you save. Keep PNG when you still need those pixels clear. WebP can keep them too.
After the change, compress if the file is still heavy, or blur if the squares are harsher than you wanted.
How to do it
- Drop one image or a batch. Files stay on this device.
- Move the slider right for larger blocks. Zero leaves the picture as it is.
- When you download, pick JPG, PNG, or WebP, and set the quality if you are not saving PNG.
- Apply, then download each file or a zip of the batch.
Tips
- A setting around 20 hides fine text and still shows the shape of the photo.
- Zero keeps the picture and only changes the file format.
- JPG fills clear pixels with white. Use PNG if you still need transparency.
- Quality around 0.92 is a good balance for JPG and WebP.
