About This Tool
This tool blurs all or part of an image in your browser: blur the whole picture for a soft background, or brush a rectangle over faces, license plates, addresses or screen content you need to hide before sharing. Because processing is local, it is suitable for anonymizing screenshots of internal dashboards, medical documents or chats before posting them in a public bug report or on social media.
How to Use This Tool
- Drop your image into the dashed zone.
- Choose Full image blur, or select Area mode to blur only a region.
- In Area mode, drag a rectangle over the sensitive part — add as many rectangles as needed (one per face or plate).
- Adjust the blur strength slider: 8-12 px hides text on a full-resolution photo; 20+ px makes the area unreadable even when zoomed.
- Preview the result, then download. The blurred output is a new file; your original stays untouched.
Advantages & Use Cases
Hide a car plate before selling parking space photos, anonymize participants in classroom or event pictures for a website, or blur a client's name in a portfolio screenshot. Support teams blur tokens and API keys in screenshots before attaching them to public issues. A soft full-image blur also works as a background for quote cards and thumbnails, keeping text overlays readable.
Supported Formats & Recommendations
- Works on JPG, PNG and WebP; output stays in the input format so transparency in PNG is preserved.
- For hiding text, prefer PNG output: JPEG compression around a blurred area can leave faint edges that hint at the original shapes.
How We Test This Tool
Each release is checked with a screenshot containing 12-point text: after a 10 px area blur, OCR software must return no readable characters, and rectangles must stay aligned after download (no 1-2 px offset). Full-image blur is verified to keep colors even, with no visible grid artifacts.

Frequently Asked Questions
Can someone reverse the blur to read the hidden text?
A strong blur (12 px or more on a full-resolution image) is destructive — the detail is mathematically discarded, not hidden. For very short text like a 4-digit code, add a second pass or also darken the area to be safe.
Does blurring change the file size?
Blurred areas compress better, so files usually get slightly smaller. The exact size is shown before download.
Can I blur several different areas with different strengths?
Apply the strongest blur first, download, then re-load the result and blur the second area with a different strength — each pass is saved as a new file.
