Frequently Asked Questions
Yes. Switch to Selective Brush mode and paint over the exact region you want blurred. Use the eraser to refine the mask and the size slider to control the brush. Everything you do not paint stays perfectly sharp.
No. All blurring, rotation and conversion happens 100% inside your browser using the Canvas API. Your images never leave your device, which makes the tool safe for private, medical and business photos.
Yes. Select multiple images or upload an entire ZIP archive. Use Apply to All to blur every image with the same settings, then download all the results as a single ZIP file.
You can export blurred images as PNG, JPEG, WEBP, BMP and ICO. JPEG and WEBP include a quality slider so you can balance file size and clarity, and a resize option lets you scale the output up or down.
Yes. Rotate 90° left or right, flip 180°, and mirror horizontally or vertically. The orientation is applied before the blur so motion and directional effects always point the right way.
Blurring is, by design, a softening effect, but our tool processes at high resolution (up to 2400px on the long edge) and exports lossless PNG by default, so you keep maximum detail everywhere outside the blurred areas.
Gaussian blur uses a bell-curve weighting for a smooth, natural softening, while Box blur averages pixels equally for a faster, slightly crisper result. Try both to see which suits your image.
Choose the Pixelate effect, switch to Selective mode, and paint over the face or plate. Increase the intensity for larger blocks that completely hide the detail.
Yes. The interface is fully responsive and touch-friendly, from small keypad phones to smartphones, tablets, laptops and 4K desktops. The selective brush works with both touch and mouse.
Unlike paid software or upload-based sites, our tool is free, requires no account, and never uploads your image. You get ten pro blur engines, a selective brush and batch ZIP processing with complete privacy and instant results.
