Quick guide
Click the image to add a region. Select a region to edit its effect and shape. Drag the region to move it, the blue corner handle to resize, and the green handle to rotate. Use the remove button to delete it.
Keyboard: arrow keys move the selected region; Shift + arrows resize; Alt + left/right rotates. Delete removes the selected region.
Censoring notes
- Black and White cover pixels with a solid color. Blur, Pixelate and Mosaic can leave information recognizable; they do not guarantee anonymity.
- Regions and effect strength keep their image position when the screen size changes. Each region has its own effect, shape, size and rotation.
- Overlapping Blur processes the existing composition rather than restoring pixels hidden by an earlier region.
- The PNG is a static image at the original resolution. Check the complete downloaded image, including mask edges, before sharing.
- Changing or removing the image clears its regions while keeping the effect preferences.
Free Online Image Censor & Redaction Tool
Protect sensitive information in your photos and screenshots with our free online image censor tool. Blur a face in a street photo, pixelate a license plate before posting a car for sale, or black out an account number on a banking screenshot: this image redaction tool offers five local effects and a full-resolution PNG export without uploading the image through this tool. Files may be up to 25 MiB.
Choose from five distinct censoring modes, Black Box, White Box, Blur, Pixelate, and Mosaic, to match any use case. Each mode is fully adjustable: set the blur radius, pixel block size, or rotation angle until the censored region looks exactly the way you want. Add multiple regions, resize them with drag handles, and switch between rectangle and ellipse shapes for pixel-perfect coverage.
Your original images are never uploaded. The finished image exports as a high-quality PNG that preserves the full resolution of the original, ready for sharing, printing, or embedding in reports and presentations.

How to Use the Image Censor Tool
- Upload your image: Click the upload area or drag and drop a JPG, PNG, WebP, or GIF file.
- Click to censor: Click directly on the area you want to hide, a censor region appears right where you click.
- Select a censor mode: Pick Black, White, Blur, Pixelate, or Mosaic from the toolbar.
- Adjust settings: Fine-tune blur radius, pixel size, shape (rectangle or ellipse), and rotation.
- Add more regions: Click "Add Region" to censor additional areas on the same image.
- Download the result: Hit the Download button to save the censored image as a full-resolution PNG.
Use Cases
- Privacy protection: Blur faces in photos before sharing on social media or public websites.
- Document redaction: Black out Social Security numbers, account numbers, and addresses in scanned documents.
- License plate censoring: Pixelate vehicle plates in dashcam footage or real-estate photos.
- Screenshot preparation: Remove usernames, emails, and personal data from screenshots before posting support tickets.
- Legal compliance: Cover personally identifiable information in an image. Using this tool alone does not establish compliance with GDPR, HIPAA or other legal requirements.
- Content moderation: Censor inappropriate content in user-uploaded images before review.
- Real estate & journalism: Protect bystander identities in street-view and news photography.
- HR & internal docs: Remove confidential salary and performance data from shared reports.
Frequently Asked Questions
Can I censor multiple areas at once?
Yes. Click "Add Region" as many times as needed. Each region can have its own censor mode, shape, size, and rotation.
What is the difference between Blur and Pixelate?
Blur softens the region (not available in every browser). Pixelate turns the region into large blocks; Mosaic fills it with tiles of averaged color. Blurred or pixelated information can remain recognizable.
Does censoring reduce image quality?
Effects are applied only inside the chosen regions. The PNG keeps the original dimensions, though metadata and compression may differ from the original file.
Does it work on mobile devices?
Yes. The tool is fully optimized for touch input on phones and tablets, with larger drag handles for easy region manipulation.
Tips & Best Practices
- Use Black Box for text: Solid black provides the most reliable redaction for printed or digital text.
- Choose Blur for faces: Blur can soften faces, but no fixed radius guarantees that an identity is hidden. Use an opaque region when recognizable details need full coverage.
- Increase pixel size for stronger censoring: Larger blocks reduce detail, but recognizable information can remain. Inspect the result rather than assuming pixelation guarantees anonymity.
- Try the ellipse shape: Ellipses follow facial contours more naturally than rectangles.
- Use rotation for angled text: Rotate the censor region to align perfectly with tilted labels or watermarks.
- Always verify before sharing: Zoom in to ensure no sensitive data is visible around the edges of censor regions.
