TOOL GUIDE

Blur a selected area without blurring the whole photo

How to use this tool

  1. Choose a JPEG, PNG, or WebP image.
  2. Drag on the preview or enter a rectangular selection.
  3. 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.

Yes. It is free to use with no signup and no daily usage caps. You can process up to 20 files of up to 30MB each in one batch, then download your results.

Does this tool find faces automatically?

No. Selection is manual. Drag over the preview or set percentage coordinates to choose the region. Check that every intended face or detail is covered before using the result.

Can I undo the blur after downloading?

The blur is baked into the exported image. Keep your original if you may need an unedited copy. Reset lets you restart the current tool session but does not alter files already downloaded.
