Image Blur: Cover Plates and Faces with Mosaic
You are listing the car, the plate shows. You are sharing the kid photo, the face is exposed. This tool pixelates your selected rectangle into unreadability. Plates, faces, phone numbers, addresses, whatever needs hiding. You set the mosaic size yourself; bigger blocks hide more. Everything happens in the browser; the photo never reaches a server.
Step by step
- Upload the image; the preview appears.
- Frame the area to hide with finger or mouse.
- Type the mosaic size; 12 starts well for plates, 16 for faces.
- Press blur and watch the area close up.
- For more areas, reframe and blur again.
- Download and zoom into blurred spots before sharing.
Example scenario
Emre sells his used car and knows plates must not show in listing photos. He uploads the image, frames the plate, sets mosaic to 12 and applies. The plate turns unreadable while the car shines. He also covers the house door number in the same photo. The listing goes live and nobody reads the plate.
Check your result
Open the downloaded image full size and try reading blurred spots; if letters peek through, enlarge the mosaic and repeat. Check no piece sticks out past edges. Keep the original separately; blurring cannot be undone.
Frequently asked questions
Can blurring be undone?
No, mosaic is permanent in the downloaded file. Keep the original, work on a copy.
Does it beat face recognition?
With a large enough mosaic, yes. Narrow covers like eye bars fall short; cover the whole face.
Can I cover several areas?
Yes, frame and blur each area separately. Everything downloads in one file.
Do videos blur?
No, photos only. See the trimmer tool for video.
Does my photo reach a server?
No. Everything runs in the browser; the file never leaves the device.
