100% in-browser — nothing uploaded
Unlike online editors that send your image to a server, RedactPix applies the blur locally with the Canvas API. Your photos and documents stay on your device.

Why use RedactPix to blur image?
Precise control over blur intensity
Adjust the blur radius from a soft haze to a heavy scramble. Every box you draw can have its own intensity — blur one face lightly and pixelate another area heavily.
Flattened export — metadata stripped
Download a single PNG with the blur baked into the pixels. GPS data, EXIF tags, and all metadata are removed automatically. No layers, no recovery.
How to blur image — step by step
From raw image to safely redacted file in four steps.
Step 01

Step 02
Select the area to blur
Drag on the image to draw a box over the area you want blurred. Or click "Scan" to let local AI find faces and sensitive text automatically.
Step 03
Apply blur and adjust
Choose "Blur" from the masking options and adjust the intensity slider. Preview the result instantly before exporting.
Step 04
Download the flattened result
Click Download to get a single PNG with the blur permanently baked in — no layers, no metadata, no trace of the original.
Frequently asked questions
Is blurring an image with RedactPix safe for sensitive documents?
Blur is applied locally in your browser — the image is never uploaded. However, for highly sensitive text (like ID numbers or passwords), a solid black box is safer than blur, because blur can sometimes leave enough detail to be recovered at high resolution.
Can I blur multiple areas in one image?
Yes. Draw as many boxes as you need — each can have a different masking method (blur, pixelate, or blackout). Mix and match freely.
What blur strength should I use?
For faces, a medium blur (radius 15-20) is usually enough. For text, use a heavier blur or switch to a solid black box for maximum security. You can preview each setting before downloading.
Does RedactPix blur faces automatically?
Yes. Click "Scan" and RedactPix detects faces on-device using MediaPipe, then suggests blur boxes you can review and adjust before applying.
