- Apply the edit, inspect the output, and download a copy.
About this edit
Blur softens detail but is not secure redaction. For sensitive text or identifying details, choose the solid fill option. Selection is manual; no automatic face detection is performed.
Your original stays unchanged
The tool creates a new image. Edits are not written back to the selected file. Reset to start again, or download the result and use it as the source for another edit.
What a local blur changes
Blurring spreads detail across nearby pixels, making an area look softer. A rectangular local blur can draw attention away from a distracting background region or soften a visual element. The rest of the image remains outside the effect, subject to the encoding chosen for the exported copy.
Select the area manually in the preview, or enter its percentage coordinates. This editor does not automatically detect faces, license plates, or text. You decide what region to cover and need to inspect whether its edges contain everything you intended to soften.
Choosing a region and strength
A small amount of blur can soften texture while leaving large shapes and lettering recognizable. A stronger setting spreads detail farther. The right visual effect depends on the source resolution as well as the strength, so compare the exported image at a realistic viewing size.
The selection uses X and Y for its top-left corner and width and height for its extent. All four values are percentages of the source. Leave enough room around the item you want to soften, because selecting only its central portion can leave identifying edges outside the blurred rectangle.
Use solid fill when information must be hidden
Blur is not a reliable redaction method. Text, faces, and other information can remain recognizable or partly inferable after blurring. A blurred region should not be assumed to make sensitive information safe to share.
The solid fill option replaces the selected pixels with a dark rectangle. Cover the full sensitive region with an adequate margin and inspect the downloaded output, not just the selection overlay. This tool only edits image pixels; it does not review the rest of the picture for other identifying information.
Exporting and checking the edited copy
Apply the effect and open the output preview. Check the border between edited and unedited areas, and look for details left outside the rectangle. If you need another region, download the edited result and use it as the next source, keeping an original separately.
Choose PNG when you want to avoid another lossy JPEG step, or use JPEG or WebP when a smaller output suits the destination. If blur is unavailable in your environment, solid fill is an alternative for obscuring a rectangle.
