Open toolIf you need to black out or mask private areas with rectangles and circles without sending files to a random server, use a browser-local tool. Toolkase’s Image Redactor keeps the work on your device.
Draw rectangles or ovals over faces, IDs, addresses, or other private details, then download a redacted image. Masks overwrite pixels in your browser — nothing is uploaded.
Why people search for “redact image”
“redact image” is usually a job-to-be-done query: you have an input, you want a result quickly, and you do not want friction (accounts, watermarks, or mystery uploads). Browser tools win when they are honest about where processing happens.
Because this workflow often involves personal files, prefer tools that process on your device. Upload-based sites may be fine for public flyers — not for IDs, medical scans, or confidential PDFs.
How to use Image Redactor on Toolkase
Open Image Redactor and follow these steps:
- Choose an image from your device.
- Pick rectangle or circle / oval, then drag over areas to mask.
- Undo or clear as needed, then download the redacted image.
That is the whole loop — open, process, copy or download.
How to verify processing stays local
After the page loads, open DevTools → Network and run the tool with a small sample file. You should not see your document uploaded as a multipart payload. You can also try airplane mode after load: if the tool still works, it is not depending on a remote processing API.
Tips for private image edits
- Start with a copy of important photos so you can redo settings.
- On phones, very large camera originals may be slow — try a smaller export first.
- Strip location metadata before sharing travel or home photos when privacy matters.
- Convert to WebP or compress after resizing for the smallest shareable file.

FAQ
- Is my image uploaded?
- No. Redaction runs on a local canvas in your browser.
- Can someone recover what I covered?
- The download overwrites those pixels with your fill color. It does not keep the original content underneath as a separate layer. Still avoid sharing originals.
- Does Toolkase upload my files when I use Image Redactor?
- No. Image Redactor is privacy-critical: processing stays on your device and files are not uploaded to Toolkase servers for this workflow.
- Is Image Redactor free on Toolkase?
- Yes. Image Redactor runs in your browser with no account required.
- Do I need to install software to use Image Redactor?
- No. Open the tool page in a modern browser and work there — nothing to install.
