Drag images here
Supported formats: JPG, PNG, WebP, GIFWhether you need to quickly anonymize sensitive data in screenshots, create an aesthetically blurred background for your website, or just want to cover faces in photos, our Image Blur Tool is here for you.
Forget launching Photoshop for simple blurring. Here you can apply a blur effect to hundreds of photos at once, set the precise blur intensity, and download everything in one package – all securely within your browser.
Why Use Our Online Blur Tool?
Our editor combines speed with precise settings, allowing you to achieve exactly the result you’re looking for.
1. Absolute Control Over Blur Intensity 🎚️
Not every image requires the same adjustment. Our tool offers you a slider for blur intensity (in pixels).
- Subtle Blur (1–5 px): Ideal for softening details or creating a “dreamy” feel.
- Strong Blur (20+ px): Perfect for absolute illegibility of text or anonymizing individuals.
- You see the result in real-time (if the tool supports preview), or simply adjust it as needed.
2. Security First – Anonymize Without Risk 🔒
Sensitive documents, car license plates, or children’s faces are often blurred. Most online editors require data to be uploaded to an external server. We don’t.
- Client-side Processing: All adjustments take place directly in your browser, using your device’s power.
- Your photos are never uploaded anywhere. What’s on your computer stays there.
3. Batch Edits and Smart Export ⚡
Do you have a folder full of product photos from which you want to create backgrounds?
- Batch Processing: Upload even 100 images at once.
- Format Flexibility: Input files can be diverse (JPG, PNG…), but you determine the output. You can unify everything into an efficient WebP, for example.
- Download as ZIP: Don’t save files one by one. At the end of the process, we’ll offer you a single ZIP archive with all the blurred images.
When to Use a Blur Effect?
Blurring isn’t just a photography mistake; it’s a powerful graphic tool:
- Privacy Protection (GDPR): Do you need to publish a screenshot, but names, emails, or passwords are visible? Blurring the entire image or parts of it (if you crop them beforehand) is the fastest way to anonymity.
- Background Creation: A sharp photo under text often looks distracting and makes the text unreadable. By heavily blurring the photo, you create an abstract, color-harmonized background on which white text stands out perfectly.
- Focus and Attention: In e-commerce and design, blur is used to suppress less important elements to highlight what’s essential (e.g., a button or a product in the foreground).
- Placeholder Images: Developers often use blurred versions of images (called LQIP - Low Quality Image Placeholders) for faster website loading before the full version is fetched.
Quality and Format Settings Guide
Our tool gives you full control over how the resulting file will look.
| Setting | Recommended Value | When to Use? |
|---|---|---|
| Blur Intensity | 5–10 px | For subtle blurring where content is still recognizable (e.g., website background). |
| Blur Intensity | 20+ px | For complete censorship and illegibility of text. |
| Output Quality | 90 % | The golden mean. The image looks great, but the file isn’t unnecessarily large. |
| Format: WebP | Always for Web | If you’re putting images on the internet, WebP ensures the smallest size while maintaining quality. |
