Anonymize Image Online
Remove identifying information from images including faces, names, badges, and IDs.
Same local editor as the homepage. This page is a deep link for one job, not a separate upload service.
Blur
Softer cover. Raise the strength until text is unreadable.
Pixelate
Mosaic blocks for faces and photos. Larger blocks hide more.
Black Box
Solid cover for names, IDs, and anything that must not be readable.
This job
Anonymize in passes, not one hopeful box
Anonymize by removing every clue a stranger could use to name someone, not by covering the center of the photo once. Do faces, then badges and captions, then background screens, plates, and house numbers. Stop when the image no longer answers who this is. The edit stays in your browser.
Anonymizing a picture means removing the ways a stranger could name the person, not applying a single effect to the middle of the frame. Do it in passes: faces and profile photos first, then name badges and captions, then screens or whiteboards in the background, then plates or house numbers if the photo is outdoors. Stop when you can no longer answer “who is this?” from the image alone.
The export is a new PNG of the pixels on the canvas, not the original file with a sticker on top. That matters because the original may still hold details you did not draw over, and because sharing the original by mistake undoes the work. This page is the same editor as the homepage. It will not certify a research protocol or a clinical release. If an institution requires a specific method, follow that method and use the canvas only for the pixel step.
Faces, then text
A covered face with a visible name badge is not anonymous.
Background screens
A monitor behind someone often shows a mailbox or a patient list.
What this is not
Not a formal anonymization review and not automatic detection.
Check at full size
Open the PNG and try to identify the person before you publish it.
How to use
How do you redact this image locally?
Load the image in this browser, draw over each sensitive region, and export a PNG. The canvas edit does not upload the file. Paste a screenshot with Ctrl+V or Command-V, or drop a JPG, PNG, or WebP. Undo fixes a box without changing the original on your device.
- 1
Upload the image you want to anonymize.
- 2
Choose how to mask identifying information: Blur, Pixelate, or Black Box.
- 3
Draw a box over faces, names, ID numbers, or any other identifying features.
- 4
Add as many masked regions as needed to fully anonymize the image.
- 5
Download the anonymized image ready for sharing or publication.
You can also paste a screenshot with Ctrl+V or ⌘V. Undo and Redo fix a box without changing the original file.
Why use this tool
Why does this stay in the browser?
This page is for images that already contain private material. Blur, pixelate, and black box run in your browser, so the file is not sent away to be cleaned. Use a black box for secrets that must not stay readable. Use blur or pixelate only after you have checked that the cover is enough.
Sharing images that contain identifiable people or personal information raises privacy concerns. Faces, name badges, location data, and visible IDs can all be used to identify individuals.
Anonymizing an image before publishing or sharing removes that risk. It is standard practice in journalism, research, healthcare, and legal work.
This tool lets you draw over any region of the image and apply Blur, Pixelate, or Black Box with no uploads or accounts required.
Questions
What should you know before you export?
The image is processed locally, and export writes a new PNG. Blur is not the same cover as a black box. Paste works with Ctrl+V or Command-V. If your question is about a specific leak, such as a password, a face, or a sidebar, use the guides linked below before you send the file.
What does anonymizing an image mean?
Anonymizing an image means removing or obscuring all information that could identify a person, such as their face, name, ID number, or address.
Can I anonymize faces in photos?
Yes. Draw a box over any face in the image to blur, pixelate, or black it out.
Is this suitable for publishing anonymized research images or documents?
This tool provides a practical way to visually anonymize images. For formal research or legal contexts, consult your institutional requirements.
My image is large. Will the tool still work?
Yes. The tool processes the image at its full native resolution in your browser. Very large images may take longer to load.
Does the tool store my anonymized images?
No. All processing happens locally in your browser. Nothing is sent to or stored on any server.
Can I anonymize license plates in photos?
Yes. Draw a selection over any region, including license plates, addresses, faces, or name badges.
What is the difference between anonymization and redaction?
Redaction typically refers to covering text in documents. Anonymization is broader and includes faces, biometrics, and other identifying features.
Can I anonymize multiple people in the same photo?
Yes. Draw a separate box over each face or identifying feature. There is no limit to how many regions you can anonymize in one session.
Will the result look professional?
Pixelate and Blur look natural in journalistic and research contexts. Black Box is common in legal and formal document redaction.
Related workflows
Which related tool should you open next?
Every tool on this site is the same local editor with a different starting note. Open a related page when the job is narrower, such as faces, screenshots, or solid black text. You do not upload the image to a second service to switch jobs.
Guides
Which guide matches this job?
Read the guide that matches the mistake you are about to make. Text secrets usually need a black box, not a light blur. Faces, plates, and sidebars need their own pass. Local editing matters most when the file should not be uploaded in order to hide it.
