Photo Censor - Blur, Pixelate & Black Out Sensitive Areas Online
Need to hide a face, license plate, or sensitive text before sharing a photo? Photo Censor lets you blur, pixelate, mosaic, or drop a solid black bar over any part of an image — right in your browser. Drag a rectangle for clean blocks, or switch to the brush to paint over irregular shapes with a live size cursor. The preview updates instantly and every image is processed locally on your device, so your photos are never uploaded to a server.
How to Use
Click the upload area or drag & drop a JPG, PNG, WEBP, GIF, BMP, or AVIF file (up to 25 MB). The photo loads straight into the editor — nothing is sent to any server.
Choose Blur, Pixelate, Mosaic, or Black Bar, then select Rectangle for clean blocks or Brush to paint freely. Adjust the intensity and brush size to match the area you need to cover.
Drag over faces, plates, IDs, or text to hide them — the preview updates live. Fine-tune with Undo / Redo (or Ctrl+Z / Ctrl+Y), and use Clear All to redo the masking from scratch.
When you're happy, click Download to save a full-resolution PNG with the censored areas permanently baked into the image.
Key Features
Softens the selected area into a smooth, unreadable haze. Adjust the intensity slider to control exactly how strong the blur is.
Reduces the region to large square pixels — the classic redaction look for faces, screens, and text.
Averages pixels into a tiled mosaic pattern, hiding detail while keeping the rough colors of the original.
Paints a fully opaque bar that completely removes the underlying pixels — the only truly irreversible option for hiding sensitive data.
Drag clean rectangles over blocky areas, or switch to the brush to paint freehand over irregular shapes. A live cursor shows the exact brush size.
Step back and forth through every mask with the buttons or Ctrl+Z / Ctrl+Y, and clear all areas in one click to start over.
Full touch support lets you censor photos with your finger on phones and tablets, just as easily as with a mouse on desktop.
All processing runs locally in your browser. Your images are never uploaded, so sensitive photos stay entirely on your device.

Frequently Asked Questions
Are my images uploaded to a server?
No. Photo Censor runs entirely in your browser using the HTML canvas — your images are never uploaded anywhere and stay completely on your device, even after you download the result.
Can the censoring be undone by someone else?
Blur, pixelate, and mosaic obscure content but are forms of obfuscation that can, in theory, be partially recovered. For information you must hide permanently — ID numbers, faces, license plates — use the Black Bar tool, which paints a fully opaque block that removes the underlying pixels from the exported image.
Is it free?
Yes — completely free, with no watermark, no sign-up, and no limits on how many images you can censor.
Does it work on my phone?
Yes. The editor fully supports touch, so you can draw censor areas with your finger on phones and tablets, with a live brush-size cursor to guide you.
What file formats are supported?
You can upload JPG, PNG, WEBP, GIF, BMP, and AVIF files up to 25 MB. The censored result is exported as a high-quality PNG at the original resolution.
What's the difference between the tools?
Blur softens an area, Pixelate turns it into coarse square blocks, Mosaic averages pixels into tiles, and Black Bar covers it with a solid opaque rectangle. Use Rectangle mode for clean shapes and Brush mode to paint over irregular areas.
Photo Censor gives you four privacy tools — blur, pixelate, mosaic, and a truly opaque black bar — with rectangle and brush selection, a live preview, undo/redo, and full touch support. It's completely free and 100% private, processing every image right in your browser.
