Censor Image Online

Censor any part of an image by drawing over it. Apply a solid black bar, blur, or pixelation to faces, text, or sensitive content. Free, browser-based, no uploads required.

Redact Sensitive Areas Before Sharing

Draw directly on your image to mark faces, text, or personal information. Choose a solid black bar, blur, or pixelation style. Everything runs in your browser — your image stays private.

100% Private · No Uploads

Why Use This Tool?

Stays on Your Device

All image processing uses the browser's Canvas API. Your file is never uploaded to any server.

3 Censor Styles

Solid black bar for maximum redaction, blur for a softer look, or pixelate for the broadcast-style effect.

Draw Multiple Regions

Mark as many areas as needed in a single pass before applying the effect all at once.

Export as PNG

Download the censored result as a high-quality PNG file, ready to share or attach to documents.

How this Censor Image Online works

Upload a photo and use the Censor Image tool to hide sensitive details before you share it. Click and drag on the preview to draw rectangles over faces, license plates, addresses, ID numbers, or any content you want to redact. Draw as many rectangles as you need — each one is listed below the canvas and can be removed individually if you change your mind.

Choose between three censor styles: a solid black bar that completely covers the area, a Gaussian blur that softens details while keeping the general shape visible, or pixelation that replaces the region with a mosaic of color blocks. Click Apply, then download the finished image as a PNG file. Your photo never leaves your device — the entire process runs in the browser, which makes this tool safe for confidential documents, personal photos, and screenshots containing private information.

Frequently Asked Questions

What does the Censor Image tool do?
It lets you draw rectangles over any part of an image and apply a black bar, blur, or pixelation effect to those areas. This is useful for redacting faces, personal information, license plates, addresses, or any sensitive content before sharing an image.
Is my image uploaded to a server?
No. All processing happens locally in your browser using the Canvas API. Your image never leaves your device and is not sent to any server. This makes the tool safe to use with sensitive documents and personal photos.
What is the difference between black bar, blur, and pixelate?
A black bar completely covers the selected area with solid black. Blur applies a Gaussian softening effect that hides detail while keeping the region visible. Pixelation replaces the area with large blocks, similar to the censoring style common in news broadcasts and gaming content.
Can I censor multiple areas in one image?
Yes. You can draw as many rectangles as you need before applying. Each region you draw is added to the list and all of them are censored together when you click Apply.
Will the censored areas be recoverable?
The black bar method is the most secure — the original pixel data is completely replaced. Blur and pixelate reduce visibility but may theoretically be partially reversed with advanced image processing tools. Use the black bar for highly sensitive content.
What image formats does the tool accept?
The tool accepts any image format your browser supports, including JPG, JPEG, PNG, GIF, WebP, BMP, and AVIF. The output is always exported as a PNG to preserve quality.
Can I undo a region I drew by mistake?
Yes. Each region you draw appears in a list below the canvas, and you can remove individual regions before applying the censor effect. Once you click Apply, the export is final, but you can start over by clearing all regions.
Is this tool free?
Yes. The Censor Image tool is completely free with no account required. You can use it as many times as you need without any restrictions.
