You want to post a photo of your car, but not its licence plate. Ninja Mask takes care of that in one tap. Choose a photo and the app finds the licence plate and covers it. No hunting around with your finger, no smearing mosaic over the picture. WHAT IT DOES Finds plates automatically Pick a photo and the app looks for licence plates and covers each one with a solid panel. Handles several vehicles at once If more than one car or motorcycle appears in the same photo, each plate is covered. Follows the shape of angled plates Seen from an angle, a plate is not a rectangle. The mask is shaped to match, so it does not look pasted on. Blends with the colour underneath Sunset, night, deep shade — a plate looks different in each. The mask takes the colour of the actual plate beneath it, so the mood of the photo is kept. White, yellow and green plates are all supported. Adjust it yourself Tap a mask and handles appear at its corners. Drag a corner to reshape, the centre to move. Hold a corner and a magnifier appears for precise work. Pinch to zoom the photo. You can also add a mask by hand. Works with plates from other countries Not only Japanese plates — plates written in Latin characters are found too. Save or share straight away Save the edited photo to your library, or send it directly from the share sheet. YOUR PHOTOS STAY ON YOUR DEVICE Detection, masking and saving all happen on your iPhone. Your photos are never sent to a server. No account is required. GOOD FOR - Posting photos of your car or motorcycle - Sharing a wash, a build or a ride - Listing a used vehicle or parts for sale - Showing someone your parking space or garage PLEASE NOTE - Automatic detection depends on the photo. A plate that is very small, at an extreme angle, dark or blurred may be missed. When that happens, please position a mask by hand. - Saving creates a new image with the mask baked in. Your original photo is not changed. - This app displays advertisements.

Hide Car Plate

Features
Read full description

Before sharing a car photo, quickly hide the car number on any visible license plate. Instead of a blur or mosaic, NumberEraser composites a custom color, text or image plate onto the photo, so it keeps its look. Detection, editing and compositing run on your device. Your photos are not uploaded to a server. ā–  When to use it - Before posting your car on social media - For used-car and parts listings on online marketplaces - When sharing car meet, event or road-trip photos with other people's cars in the frame - For blog and video thumbnails ā–  Three steps 1. Choose a photo 2. License plates are detected automatically and a replacement plate is composited over them (drag the four corners to fine-tune, or add a plate by hand) 3. Save to your photos, or share to messaging apps and social media ā–  Automatic license plate detection An on-device model detects each license plate and estimates its four corners. The replacement follows the angle of the original plate, and the photo is also checked in sections so small plates on cars in the background are easier to find. Choose a detection level - strict, standard or lenient - to balance false detections against missed plates. If a plate is missed, add a frame and adjust it by hand. ā–  Why not just blur it? A blur or mosaic makes it obvious that something was hidden. NumberEraser composites a plain or text plate over the number instead, so the car photo keeps its look. The "Auto" plate fills in with the color of the plate in the photo, so it blends in with the car. ā–  Composite plates you can choose or design Start from samples in the plate colors used in your region, or create your own: a solid color, a plate with text such as PRIVACY, or an imported image. Pick colors from a palette, a color picker, or with an eyedropper on the photo. Choose the border color and width and one of five fonts. ā–  Blend into the photo For plates other than Auto, a slider pulls the composited plate toward the color of the plate in the photo, so it is less likely to stand out in a dark parking lot, evening light or shade. ā–  Plate shapes by region Plate previews follow the proportions used in Japan; North America; Europe, the UK and Korea; China; and Australia and New Zealand, and can be switched at any time. ā–  Privacy - License plate detection and compositing run on your device; your photos themselves are not sent to a server - Saved images do not carry over the original photo's EXIF metadata, including location - Your original photo is left unchanged; the edited photo is saved as a new image - The app is free and shows ads
