Use local pixelation for one area or the whole image
Pixelate a face, license plate, address, order number, or one line of chat content with a local region. If you need a full mosaic effect, switch to full-image pixelation without leaving the page.

Pixelate images online with partial or full-image mosaic
This online image pixelator is built for quick privacy masking in screenshots and photos. Drag to pixelate one area, pixelate the full image, and switch between mosaic, solid cover, and blur based on what needs to be hidden.
Better suited to screenshots and private details
Chat screenshots, payment screenshots, dashboard captures, and ID images often should not be uploaded to unknown servers. This tool keeps preview and export in the browser.
Switch between pixelate, solid cover, and blur
Mosaic is best for obvious censorship, solid cover is better for stronger privacy, and blur is useful when you want a softer result. You can also add multiple regions before export.
When an online image pixelator is useful
Online pixelation is commonly used for privacy before publishing content. It is practical for hiding visible details quickly, but it is not the same as a formal redaction workflow.
Chat screenshots and order screenshots
Before sharing chat logs, support screenshots, order details, or payment records, pixelate names, phone numbers, addresses, and order IDs.
Faces and license plates in photos
Street photos, event photos, parking images, and product shots sometimes capture unrelated people or visible plates. Local pixelation is faster than re-editing the whole image.
Private details before publishing content
Screenshots used in social posts, blog articles, help docs, and support pages often need personal information, account details, or internal data hidden before they go live.
Frequently asked questions
Common questions about pixelating images online, adding mosaic to part of an image, censoring screenshots, and hiding sensitive details.
How do I pixelate part of an image online?
Upload an image, drag on the preview to create a pixelate area, then move or resize it as needed. After that, adjust pixel strength, preview the result, and download.
Can I pixelate just a face or a license plate?
Yes. This tool is built for partial pixelation, so you can target a face, a license plate, an address, a username, or one line of chat content without affecting the whole image.
Can one image have multiple pixelate regions?
Yes. If one image contains several sensitive areas, such as an avatar, a name, an address, and an order number, you can add multiple pixelate regions before exporting.
What is the difference between blur and pixelate?
Pixelate turns the area into visible square blocks and usually looks more like deliberate censorship. Blur softens edges and looks more natural. For screenshots and sensitive text, pixelate is often clearer.
Is this tool good for chat screenshots?
Yes. Chat screenshots, dashboards, payment captures, and order screenshots often only need a few local censor regions instead of full-image editing.
Are my images uploaded to a server?
No. Image preview, pixelation, and export all run locally in the browser. The source image is not uploaded to a server.
Can I pixelate the whole image instead of one part?
Yes. This page supports both partial pixelation and full-image pixelation, so you can switch depending on whether you need privacy masking or a full mosaic effect.
Should I use solid cover instead of pixelate?
Use pixelate when you want the usual mosaic censorship effect. Use solid cover when the hidden detail is more sensitive and you want stronger visual blocking.

After censoring sensitive details, you may still want to compress, crop, or switch to a softer blur effect before sharing the image.
