However, it is preferable to use CSS styles rather than having to set fixed attributes to these images unless absolutely necessary when you want to receive these values dynamically, in which case inline styling can also be used. In this article, we learned how to resize images in React by looking at the various options available to us. Other CSS properties, such as max-width, min-width, max-height, and min-height, can define the maximum and minimum values an image can hit, limiting distortion. This property can accept a variety of values such as contain, cover, fill, none and scale-down. It's always a good idea to include the object-fit property, which specifies how an image should be resized to fit its container. When we use the height, width, max-height, and other CSS properties to resize our images, they tend to distort them, making them shrink or stretch. This can be fixed by using object-fit: cover. The main drawback of this method is that fiddling with the height and width tends to distort images, making them shrink, stretch or otherwise lose their ratio. In traditional HTML, one way to resize images is to make use of the height and width property with the img tag and this also works with React:ĭownload the eBook import Logo from './images/react-logo.png' How to Resize an Image With the width And height Attributes Begin the first step with installing the new react application using the npx create react cli command. If we have many images that need similar styling and don't want to use external styling, we could create an object to hold these styles objects and then add the object to the styles attribute: import Logo from './images/react-logo.png' Ĭonst myImageStyle = Step 1: Set Up New React App Step 2: Add React Image Crop Package Step 3: Implement Image Resizing in React Step 4: Update App Js File Step 5: Start React App Set Up New React App. We will make use of string for the styles' key value: import Logo from './images/react-logo.png' The style attribute value must be a JavaScript object with key-value pairs: import Logo from './images/react-logo.png' īy default, the basic unit is in pixels, but suppose we want to make use of other units like rem, %, vh, etc. We used external styling in the previous example, but just like in traditional HTML, we can use the style attribute to add CSS styling. How to Resize an Image With Inline Styles For that you can run this command.Note: we used img as the selector, we can decide to give it a className and make use of it as the selector. You can visit this link if you are using bare-react-native.įirst we need to install: expo-image-manipulator. You can also use it if you are using bare-react-native cli but for that you need to go some extra miles and unfortunately I am not covering that here. If you want more information on it then you can go to this link. Now, import the Resizer utility from the react-image-file-resizer library. Inside the expo we have an expo-image-manipulator which we can use to compress image size and also for other manipulations as well like flip, rotate, crop etc. So, in this small post I will teach you guys how we can compress the Image size in React Native Expo.įor that you don’t need to do any special coding because expo has a cool npm package which we can use to decrease or compress image size. And if I were just a normal user this would not be a topic of discussion but because I am a programmer it costs my cloud storage. (if downloaded) Easy cropping UX using react-easy-crop.
