What is a image annotator?

learn more about this tool
This tool adds various annotations (text, labels, arrows, boxes) to images. They are overlaid on top of the input images and can be easily customized using options for color, font, size, position, and alignment. Now, let's go into detail. The annotation you want to add to the image can be specified in the text field provided in the options. It can contain any textual letters and characters, including Unicode emojis. You can color it in any desired color and also add a background fill underneath it. Additionally, you can apply a shadow effect to the annotation text by specifying shadow properties such as offset, blur radius, and color. For example, "1px 2px 3px gray". You can determine the font size for the annotation text based on the size of the input image. You can also specify the line height of the annotation text, which determines the vertical spacing between lines. The font for the annotation can be chosen from a list of available options. The list includes popular fonts such as Arial, Times New Roman, Helvetica, and more. You can also import a custom font from a URL. The annotation text can be formatted in bold or italic style. The position of the annotation is controlled by placing a rectangular region on the image. This can be done either in the input preview by dragging the mouse or in the options using parameters such as the left position (X-coordinate of the annotation's left position), top position (Y-coordinate of the annotation's top position), width (width of the annotation label), and height (height of the annotation label). You can also align the annotation text within the rectangular region to the center, left, or right. For saving the annotated image, the available formats are PNG, JPEG, and WebP. Image-abulous!

Image annotator examples

Click to use
Add a Formula to a Newton's Cradle
In this example, we use an image annotation program to comment on a physical experiment. We upload an image of a Newton's Cradle example and add the annotation "m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'". This formula describes the system and represents the law of conservation of momentum, which states that the sum of the momenta of the objects in a system remains constant if no external forces act upon them. To display the formula, we use bold Arial font in black color on a white rectangular background. (Source: Pexels.)

Add a Color Label to Image
In this example, to study colors in design courses, it was necessary to visualize the "Gold" color. For this, we upload an image of a lemon on a golden background and add a label with the color name in hex, RGB, and HTML/CSS format. For good contrast, we choose black color for the text (without background) and use the popular sans-serif font Helvetica, aligning it to the left. (Source: Pexels.)

Annotate an Image with a Quote
In this example, we annotate an image of a hiker in the mountains with a short and powerful quote to inspire viewers. We enter the quote by the ancient Chinese philosopher Lao Tzu in the options and position it at the top of the image. To give the annotation an appealing look, we choose the custom font Raleway and apply a shadow effect with a blur radius of 6 pixels. (Source: Pexels.)
