Blur Image
Blur or pixelate an entire picture — for a soft background or a placeholder — or switch to “Selected areas” and drag a box over each face, number plate, address or password you want gone before you share the file. Nothing is uploaded.

How to use
- Drop your image.
- Choose Whole image, or Selected areas and drag a box over each thing to hide.
- Pick blur or pixelate and set the strength.
- Click Apply effect and download the new file.
How it works
Blur uses the browser's Gaussian blur; pixelation shrinks the region to large blocks and scales it back up with smoothing off. Strength runs from 1 to 50 and is scaled by the picture's own size, so one setting looks similar on a 600 px thumbnail and a 4000 px photo.
In “Selected areas” mode each box is processed with a margin of the surrounding image, so the blur has real pixels to sample at its edges and the rectangle does not show as a hard-edged patch. You can add as many boxes as you need; drag them to move, drag the corner handle to resize.
Either way the pixels are replaced rather than covered. The output file holds only the obscured version — there is no sharp copy hidden underneath, and no overlay for anyone to peel off, which is the difference between this and drawing a shape over a photo in a viewer. PNG and WebP keep their format; anything else comes out as JPEG. In whole-image mode you can drop a batch and treat them all at once.
Examples
- A face in a holiday photo
- Select areas, box each face, pixelate at high strength, and the faces are gone from the file you post.
- A screenshot with real data
- Box the names, the account number and the e-mail address; the layout stays readable, the data does not.
- A website background
- Whole image, blur at high strength, and the photo works behind white text.
Common uses
- Hiding faces before posting a photo
- Covering a number plate, address or account number
- Cleaning a screenshot for a bug report or a tutorial
- Soft background images and low-detail placeholders

Frequently asked questions
Can I blur only part of the image, like a face or a number plate?
Yes — switch the first control to Selected areas. A box appears on the picture; drag it over what you want hidden, resize it by its corner, and add more boxes with Add an area. Only what is inside the boxes is changed.
Is blurring enough to hide a password or a name for good?
It depends how hard you push it. The pixels really are replaced, so there is no sharp copy left in the file — but a light blur or coarse pixelation over text can sometimes be reversed by testing candidate words against the pattern, and that has been done to published documents. For text that must stay secret, use pixelation at high strength, check the result at full zoom, or crop the area away entirely.
Does blurring remove the location stored in a photo?
No. GPS coordinates and camera details live in the file's metadata, not in its pixels, and blurring a face leaves the street it was taken in recorded in the file. Run it through Remove Image Metadata as well before publishing.
Which is better, blur or pixelate?
Blur looks softer and suits backgrounds. Pixelation destroys more detail at the same strength and reads as deliberate, which is what you want over a face or a figure — nobody wonders whether you merely missed focus.
How many areas can I blur at once?
As many as you like. Each one is a separate box with its own position and size, and they can overlap.
Can I process several images at once?
In Whole image mode, yes: drop a batch, set the effect once, download the results together. Selected areas works on one picture at a time, because the boxes have to be placed on each one.
Are my images uploaded?
No. The effect is applied in your browser, so the picture never leaves your device and nothing is stored on a server.
