Pixelate & Censor
Paint a pixel mosaic or a blur straight over the parts of a photo you need to hide — faces, plates, addresses, numbers — while everything else stays sharp.
How to pixelate or censor part of a photo
- 1
Open your image
Drag a photo onto the canvas, paste it from your clipboard, or click to pick a file. It opens instantly in the browser with nothing sent anywhere.
- 2
Pick pixelate or blur
Choose the pixel mosaic for hard censoring of text and faces, or the blur for a softer cover-up. For true privacy, pixelate is the safer of the two.
- 3
Set strength and brush size
Turn the pixel size or blur amount up until the area is unreadable, then size the brush to the detail — small for a name tag, larger for a face.
- 4
Paint over what you want to hide
Brush directly across each face, plate, number or line of text — or switch to rectangle mode and drag a box. Keep going to cover several spots; the untouched parts of the photo stay crisp.

Download the result
Export as PNG, JPG, WebP or AVIF at the quality you set. No watermark, no account, no cost — and the original file on your device is untouched.
Why use PicStudio for this?
Most photos are fine to share except for one small thing in them. A screenshot is helpful but it has your email in the corner. A photo of your car for a listing is great until you notice the plate is dead center. The group shot is perfect but one person asked not to be tagged or shown online. This tool exists for that one thing: you brush only over the spot that needs to disappear and leave the rest of the frame untouched.
Blur or pixelate faces, plates, and private details.
You can work with a brush or a draggable rectangle, and the difference matters more than it sounds. Faces, signatures and handwritten notes are rarely neat boxes, so painting over the actual shape covers awkward edges a rectangle would miss or over-crop — the stroke previews translucently as you paint and applies the moment you release. The rectangle is still there for screenshots and anything genuinely box-shaped. Switch between a chunky pixel mosaic and a soft blur, dial the pixel size or blur amount up or down, and resize the brush so a single name tag and a whole face each get the right coverage. Covering five plates in a parking-lot photo is just five passes, and each stroke is its own undo step.
Redacting is the kind of edit that should never touch a server, and here it doesn't. The image loads and is processed entirely on your device, so a passport scan or a screenshot of a private chat is never uploaded, stored or seen by anyone but you. There's no account to make, no watermark on the result, and no cap on how many areas or how many photos you redact. Drag a file in and you're already working.
One thing worth knowing: a faint blur can sometimes be undone or guessed at, especially over short text like a four-digit number. When the goal is real privacy rather than a soft look, push the pixel size or blur strength high enough that the content is unreadable, and paint slightly past the edges so nothing peeks out. Zoom in for tiny details like eyes or small print so your strokes land where you mean them. When it's covered, export to PNG for clean edges, JPG for the smallest file, or WebP for a balance of both. If you'd rather soften the whole picture instead of one spot, the Blur Image tool handles the entire frame, and Draw on Photo lets you add arrows or boxes on top.

Frequently asked questions
Is the Pixelate & Censor tool free?
Yes, fully free. No sign-up, no watermark on the download, and no limit on how many areas or how many photos you redact.
Are my photos uploaded anywhere?
No. Everything runs in your browser, so the image is processed on your own device and never leaves it. That's exactly what you want when you're hiding sensitive details.
Should I use pixelate or blur for privacy?
Use pixelate at a high pixel size. A mosaic destroys the underlying detail, while a light blur can sometimes be reversed or guessed — keep blur for cosmetic softening, not real censoring.
Can someone recover what I censored?
If you use a strong pixelation or heavy blur, the detail is gone from the exported image and can't be brought back. Faint effects over short text are the main thing to avoid.
Can I censor several areas at once?
Yes. Each brush stroke or rectangle applies on its own, so you can cover as many faces, plates or numbers as a photo contains — and undo removes them one at a time.
Which formats can I open and export?
You can open JPG, PNG, WebP and HEIC files, and export your censored image as PNG, JPG, WebP or AVIF at a quality you choose.
Does it work on a phone?
Yes. The tool is touch-friendly and runs in your mobile browser with no app to install — brush over areas with your finger and pinch to zoom in on small details.
