Photo Blur & Pixelate Tool Draw boxes over faces, plates or private info and blur or pixelate them instantly — your photo never leaves your device

What is the Photo Blur & Pixelate Tool?

This free online tool runs entirely in your browser. Drag in a photo, then draw a box with your mouse or finger over any face, license plate, ID number, address, or private information visible in a screenshot. Choose either "Pixelate" or "Blur", adjust the intensity, and watch the live preview update instantly. When you're happy with the result, download it with one click — no photo-editing software required.

🔒 Privacy first: every box you draw and every pixelation or blur effect is computed using the browser's built-in HTML5 Canvas API on your own device. Your photo is never uploaded to any server and nothing is stored — refreshing the page clears everything. That matters a lot when the photo contains faces, license plates or ID numbers you don't want to hand over to an unknown cloud service.

Common Use Cases

• Blur strangers' faces: before sharing travel, street or party photos, box out the faces of bystanders who didn't agree to be shown.
• Hide license plates: before posting dashcam footage, used-car listing photos or parking-dispute screenshots, cover the plate so the owner can't be identified.
• Redact ID documents: before uploading a passport, driver's license or ID card for an application, blur out the name, ID number or address fields.
• Anonymize screenshots: before sharing chat, invoice or order screenshots online, cover phone numbers, emails or account details.

How to Use It (3 Steps)

1. Upload a photo: drag and drop, or click to select a JPG, PNG or WEBP file.
2. Draw boxes and set the effect: drag over the photo to create as many boxes as you need; each box has its own effect (pixelate or blur) and intensity, and can be resized or deleted independently.
3. Check the preview and download: the live preview on the right shows the final result — download it once you're satisfied.

Pixelate or Blur — Which Should You Choose?

Pixelation chops the selected area into large solid-color blocks. It is the more thorough option — the original content is essentially impossible to reconstruct — so it's the right choice for license plates or ID numbers that must be fully unreadable. Blur softens the details while keeping a rough outline and color tone, which looks more natural and works well for faces or background bystanders where you just want to reduce recognizability rather than destroy the content completely. The higher the intensity, the larger the pixel blocks or the stronger the blur.

Frequently Asked Questions (FAQ)

Q1: Is my photo uploaded to your servers?

No. This tool is entirely client-side — drawing, pixelating and blurring all happen inside your own browser, and our servers never see the photo. That's different from many "automatic face detection" tools that quietly upload your image to the cloud to run their AI model.

Q2: Why isn't there an automatic face-detection feature?

Automatic face detection requires loading a large machine-learning model, which slows the page down and still can't guarantee 100% accuracy — profile views, masks and license plates are frequently missed entirely. Manual selection takes one extra step, but it's fully under your control with zero risk of a missed spot, and it also works on plates, document fields and other objects that face-detection models simply don't recognize.

Q3: Can I draw multiple areas on one photo?

Yes. You can draw as many boxes as you need on the same photo, each with its own independent effect and intensity, and each can be resized or deleted on its own.

Q4: Does it work on mobile?

Yes. Drawing, dragging and resizing all support touch input, so the experience on phones and tablets matches using a mouse on desktop.

Q5: Can the result be reversed back to the clear original?

Pixelation destroys the original pixel data and generally cannot be perfectly reversed; blur is theoretically reversible but extremely difficult in practice. If you need a genuinely reversible mask for text content, try our PII Mask & Restore Tool instead.
