Welcome to the most versatile and secure Blur Image Tool available on the web. In today's digital age, sharing images online is a daily occurrence, whether for social media, professional portfolios, or documentation. However, privacy concerns and the need for aesthetic refinement often go hand in hand with image sharing. Our tool addresses both needs by providing a robust, client-side solution for selectively blurring parts of an image or creating stunning depth-of-field effects.
Unlike traditional photo editing software that requires heavy installations or costly subscriptions, the Randomly.online Blur Tool operates entirely within your web browser. This means you get the power of a professional editor—complete with adjustable blur intensity, feathering controls, and shape selection—without the lag or complexity. We utilize advanced HTML5 Canvas technology to render effects in real-time, ensuring that your edits are smooth and responsive, regardless of your device's processing power.
Using the Randomly.online Blur Image Tool is designed to be intuitive and fast. Follow this step-by-step guide to master your edits:
1. Upload Your Image: Start by dragging and dropping your image file directly into the large upload zone. Alternatively, click the zone to open your device’s file browser. We support all major image formats including JPG, PNG, and WEBP. Once uploaded, your image will appear in the main canvas area, ready for editing.
2. Select Your Area: Immediately after uploading, you will see a selection box overlaying your image. You can drag this box to move it anywhere on the canvas. To resize the selection, simply grab any of the corner handles and drag them inward or outward. This selection defines the boundary between the blurred and sharp areas of your image.
3. Choose Your Mode & Shape: Use the control panel on the right (or bottom on mobile) to customize the effect.
- Blur Selection: Choose this to blur everything inside your selection box. This is ideal for hiding faces or sensitive text.
- Blur Background: Choose this to keep the inside of the box sharp and blur everything outside it. This creates a focus effect.
- Shape: Toggle between "Rectangle" for documents and boxes, or "Circle/Oval" for faces and organic objects.
Is my data private and secure when using this tool?
Privacy is our top priority at Randomly.online. When you use our Blur Image Tool, all image processing occurs locally within your own web browser. Unlike many other online editors, your images are never uploaded to our servers or stored in any cloud database. The JavaScript code runs directly on your device (computer, tablet, or phone), manipulating the image data in your browser's memory. This ensures that your sensitive photos, documents, and personal data remain 100% private and under your control at all times. You can even use the tool while offline once the page has loaded!
How does the "Feather" control work and why should I use it?
The "Feather" control is a feature often found in professional photo editing software like Photoshop, and we've brought it to the web. Without feathering, the transition between the blurred part of your image and the sharp part is a hard, crisp line. This can often look artificial and make the edit obvious. Increasing the Feather value applies a gradient transparency to the edge of your selection mask. This creates a soft transition zone where the blur gradually fades into sharpness. We highly recommend using at least a small amount of feathering (5-10px) for almost all edits to ensure the final image looks natural and professionally processed.
