How to Add a Censor Bar to an Image Online
A censor bar hides a selected part of an image while leaving the surrounding context visible. It is useful for editorial images, screenshots, memes, and other content where cropping would remove too much or a visible cover communicates that something was intentionally omitted. ImgToolkit's Image Redaction tool lets you draw one or more rectangular areas and apply a solid cover, blur, or pixelate effect directly in your browser.

Step-by-Step Guide
7 steps · takes under 1 minute
Decide which area needs censoring
Choose the exact word, object, or rectangular region to hide. Leave enough of the surrounding image visible to preserve the context you want readers to understand.
Open the Image Redaction tool
Go to ImgToolkit's Image Redaction tool. It accepts JPG, PNG, and WebP files and does not require an account or an installation.
Upload your image
Drop the image into the upload area or choose it from your device. Processing happens locally in your browser while you edit.
Draw the censor bar
Drag a rectangle across the content you want to conceal. Make the rectangle wide enough to cover the complete word or object, including edges that might otherwise remain recognizable.
Choose a solid cover
Select Solid cover for the classic black-bar appearance. Use Blur or Pixelate instead when you want to show that content is present without displaying it clearly.
Add and review any extra bars
Create another rectangular cover wherever the same restricted content appears. Review the whole image for captions, labels, reflections, or nearby details that undermine the censoring.
Download the censored image
Download the full-resolution PNG and open the exported file separately before publishing. Confirm that every intended area is covered and that the censor bars do not hide important context by accident.
