"Image Scrubber" that can easily delete Exif information of photos, write and blur

If you publish the photo taken with your smartphone as it is, information such as the date and time the photo was taken and the name of the device will remain, and there is a possibility that the individual will be identified. In some cases, it may be necessary to blur the subject. In such a case, the browser-based image processing service "Image Scrubber"is. All the processing is completed on the browser, and it is said that the unprocessed photos will not be stored or sent to any server, so I actually tried using it.

Rotate 90 degrees clockwise with each click.

If you select "Paint", you can write on the image with a brush. If this is OK, you can save it with "Save image".

If unsuccessful, select "Undo" and trace the part processed with the brush in the same way to cancel the processing of the corresponding part.

Blurring can be done with "Blur".

The size of the brush and the strength of the blur can be changed with the slider at the top.
