How to Censor an Image
Upload a photo, drag boxes over anything sensitive, choose pixelate, blur, or black box, then download. Your photo never leaves your browser.
Upload the photo you want to redact.
Choose a censor style: pixelate, blur, or black box.
Click and drag on the image to draw boxes over faces, plates, addresses, or documents.
Adjust pixel size or blur strength, then download the censored PNG.
What to Redact Before Sharing
Before posting photos publicly, scan for faces of people who did not consent, especially children. License plates are a common oversight in car photos and can be linked to registration data. Screenshots often contain names, email addresses, account numbers, or API keys in the background. Home photos can reveal your address through mail, packages, or house numbers visible in the frame. Even reflections in windows, mirrors, and sunglasses can leak faces or screens. Draw a box around each item and double check the preview at full size before downloading. For documents, black box is clearest because it leaves no doubt the content is hidden. For social photos where aesthetics matter, pixelate or blur keeps the image pleasant while protecting privacy. Remember that metadata can also leak information: many phones embed GPS coordinates in photo EXIF data. This tool strips metadata automatically because canvas exports contain no EXIF, which is an extra privacy win.
Technical Notes
Boxes are stored as relative coordinates, so they stay aligned if you change settings. Pixelation works by downscaling the boxed region to a tiny grid and scaling it back up with smoothing disabled, which creates the classic blocky look. Blur uses the canvas filter pipeline. The export renders at up to 1400 px, which preserves plenty of detail for sharing while keeping files manageable. Everything runs locally, so there is no upload delay and no privacy risk from server processing.
Frequently Asked Questions
Which censor style should I use?
Pixelate is the classic choice for faces and license plates and clearly signals redaction. Blur looks softer and more natural in lifestyle photos. Black box is the strongest visual redaction and works well for documents and screenshots. All three are applied permanently to the downloaded file.
Is the redaction permanent and secure?
Yes. The censoring is baked into the pixels of the downloaded image. However, never share the original unredacted file alongside it, and note that heavy pixelation with small block sizes can sometimes be partially reversed by AI tools, so use larger pixel sizes for highly sensitive content.
Can I censor multiple areas?
Yes, draw as many boxes as you need: faces, license plates, addresses, documents, and anything else sensitive. Each box is stored as a separate region, and you can undo the last one individually or clear them all at once. The selected style and intensity apply to every box, and the preview re-renders instantly so you can verify full coverage before downloading.
What pixel size works best?
For faces, 12 to 24 px blocks at typical photo sizes hide identity well while looking clean. For license plates or small text, use smaller blocks around 8 px so the box stays tight. Larger blocks are safer for sensitive content because they destroy more detail.
Does this work on mobile?
Yes, touch drawing is fully supported on phones and tablets. Tap and drag directly on the image to draw censor boxes. For precise placement on small screens, rotate your phone to landscape for a larger canvas, or use a stylus. All controls, including pixel size and blur strength, work the same as on desktop.
Will my photo be uploaded to a server?
No. Redaction runs entirely in your browser with the Canvas API, and your photo never leaves your device. This matters especially for sensitive images: unlike many online tools that upload your files to a server for processing, here there is zero transmission, zero storage, and zero third-party access.
