Create a new Image object and set its src property to the base64 image string.To resize or change the resolution of a base64 image in Javascript using the Image object, you can follow these steps: In this example, we set the media type to 'image/png' and include the base64-encoded image data after the comma.

The data URL has the following format: data. Note that the toDataURL() method returns a data URL containing the base64-encoded image data. Finally, we get the resized base64 image by calling the toDataURL() method on the canvas element. We then get the canvas context and draw the image onto the canvas with the desired dimensions. We then wait for the image to load before creating a new canvas element and setting its dimensions to the desired resized dimensions. In this example, we create a new Image object and set its source to the base64 image.

src = 'data:image/png base64,iVBORw0KG.' // Wait for the image to load

Create a new Image object var img = new Image ( ) // Set the source to the base64 image
