How to use it
- Upload a PNG, JPEG, or WebP image
- Choose Blur or Pixelate, then Entire image or Selected area
- Set the intensity, and for a selected area drag the frame or type exact X, Y, width and height
- Click Apply effect and download the result
Choose one of two effects — a blur or a pixelation — and one of two scopes: the entire image, or a single rectangular area that you move and resize with corner handles, the arrow keys, or exact X, Y, width and height fields. The area is stored in the image's own source pixels, so it stays accurate on any screen and pixel density, and the preview and the export use exactly the same geometry and effect. One intensity slider (a 1–20 level, not a percentage) controls the blur radius or the pixel-block size; both scale with the image or area so the result looks consistent from a small thumbnail to a large photo. The exported image keeps the source format and the exact original dimensions — it is not resized, cropped or compressed — and JPEG and WebP are re-encoded, so EXIF, XMP or ICC metadata may be changed or dropped. Blur and pixelation only hide content visually and can sometimes be partly reconstructed; they are not secure, irreversible redaction. If you need that, remove the sensitive content rather than relying only on this tool. Unlike Image Cropper (which removes the area outside a selection), Image Watermark (which adds an overlay) or Image Rotate & Flip (which changes orientation), this tool only obscures pixels in place. Nothing you load is uploaded or stored anywhere.
FAQ
Blur softens the area with a smooth gradient so shapes bleed together. Pixelation replaces it with large uniform squares. Both hide detail; pixelation keeps a blocky structure while blur removes edges. Pick whichever look you prefer for the same purpose.
Yes. Choose Selected area and a single rectangle appears, centered on the image. Move and resize it with the corner handles, the arrow keys, or the X, Y, width and height fields; only that rectangle is blurred or pixelated.
No. Blur and pixelation only obscure content visually and can sometimes be partly reconstructed, especially at low intensity. For irreversible redaction, remove the sensitive content from the image rather than relying only on an effect.
No. The output canvas uses the exact dimensions of the decoded image, so the result has the same width and height as the original. The tool does not resize, crop or change the file format.
No. The image is decoded, processed and saved entirely in your browser using its own canvas. Nothing is sent to a server, and analytics only records that the tool was used.
