How to blur or pixelate selected image regions
Select only the areas you want to change, then combine different treatments in one image. Solid covers are useful when blur or pixelation would leave information recognizable.
- Open a JPEG, PNG or WebP image within the stated limits.
- Choose pixelation, blur or a solid cover and drag across the preview.
- Select a region to adjust its coordinates or undo unwanted selections.
- Turn off original preview, choose a format and download the flattened edited image.
Who needs to hide part of an image
Many everyday images contain details that should not be shared. A screenshot for a support ticket may show an email address or an order number. A photo of a street may include a car license plate or a house number. A team picture for a blog may include a visitor who did not agree to appear online.
This editor helps in each of these cases by letting you mark rectangles on the picture and treat each one differently. A teacher can cover student names on a class photo. A seller can pixelate a shipping label before posting a product image. A developer can blur a token in a screenshot before adding it to documentation.
A worked example with real coordinates
Say you open a 4000 by 3000 pixel PNG, which is 12 million pixels and within the 16 million pixel limit. You want to hide a name badge near the bottom left. You choose Pixelate, keep the strength at 20 px and drag a box across the badge.
You then select Region 1 and type exact values: X 10, Y 80, W 30 and H 8, all in percent. On this image that becomes a box starting 400 pixels from the left and 2400 pixels from the top, 1200 pixels wide and 240 pixels tall. At a block size of 20, the area is rebuilt from a grid of 60 by 12 squares, so 720 flat color blocks replace the badge.
Next you switch the treatment to Solid cover, pick black and draw a second box over a phone number. Region 2 keeps its own mode and color, while Region 1 stays pixelated. You untick Show original, choose JPG at 85 percent quality and download a file named after the original with -edited added.
How the three treatments work
Pixelate shrinks the selected area to a small grid and scales it back up without smoothing, so each block shows one averaged color. The strength slider, from 2 to 80 px, sets the block size. Blur applies a Gaussian style filter with the slider value as its radius and samples a margin around the box so the edges blend.
Solid cover fills the box with a single opaque color of your choice. Because no original pixels remain under it, it is the safest choice for text such as account numbers. Regions are applied in the order you drew them, and the export is drawn at the image's full original resolution. JPG output gets a white background, since JPG cannot store transparency.
Common mistakes to avoid
The biggest mistake is trusting a light blur or small blocks on short text. Large letters, faces and numbers can still be guessed from a soft shape. Raise the strength, or use a solid cover for anything sensitive, then zoom in on the downloaded file to check it.
Other slips are easy to prevent. Leaving Show original switched on blocks the download, so turn it off first. Do not stretch one box over a whole page when two small boxes would do. If you need more than twelve regions, download the first pass, reopen that file and continue.
Useful tips and limitations
- Use an opaque cover for sensitive text; blur and pixelation may still reveal information.
- Coordinate fields offer a keyboard alternative to drawing with a mouse or touch.
- Draw the box slightly larger than the text you are hiding so the edges of letters are not left visible.
- Choose PNG for screenshots with sharp text, because it avoids the soft artifacts that JPG compression can add around covered areas.
Common questions
Can I apply different treatments to separate regions?
Yes. Each new region stores its chosen treatment, strength and cover color. Add up to twelve regions per pass.
Can the exported blurred image be edited as layers?
No. The export is a flattened image. Keep your original separately if you need to start over.
What happens to transparent areas when I export as JPG?
JPG does not support transparency, so the tool places the image on a white background before saving. Choose PNG or WebP if you need to keep transparent areas.
Can I fix a region after I have drawn it?
Yes. Pick the region from the list and edit its X, Y, width and height in percent. You can also undo the last region, redo it, or reset all edits.
Does the tool find faces or text automatically?
No. It has no automatic detection. You decide where each region goes, so check every part of the image yourself before sharing it.
