A fast, private and browser based tool to annotate images without uploading them anywhere.
This online annotate image tool allows anyone to quickly add notes, drawings, highlights and text to images directly inside the web browser. No installation or registration is required and all processing happens locally on your device.
Digital image annotation became popular long before modern apps existed. Early internet users annotated images using basic paint programs and shared them through email and forums.
Image annotation tools originated from desktop graphics software in the 1990s. As the web evolved, cloud based editors appeared, but concerns about privacy and data ownership led to a return toward local browser based solutions. Modern HTML5 canvas technology now allows powerful annotation capabilities without sending any data to external servers.
