React Js Display Image Selected from Input Type File
React Js Display Image Selected From Input Type File : In Reactjs, to display an image selected using an <input type="file">
, begin by creating a state variable to hold the selected image file. Attach an onChange
event handler to the input, updating the state with the chosen file. To display the image, use an <img>
tag with its src
attribute set to URL.createObjectURL(selectedFile)
. This approach converts the file into a temporary URL that the <img>
tag can render. Remember to handle any clean-up, such as calling URL.revokeObjectURL()
when the component unmounts or when the image changes.

How can I use Reactjs to display an image selected from an <input type="file">
element?
This ReactJS code snippet uses the useState
hook to create a simple app that allows users to select an image using the file input type. The selected image is stored in the selectedImage
state, and its preview is displayed by setting the previewImage
state using the URL.createObjectURL()
method.
The handleImageChange
function captures the selected file, updates the state, and generates a preview URL. The user interface includes a file input and, if an image is selected, displays the preview using an <img>
element.
