React Native has an<\/span><span style=\"font-weight: 400;\"> image <\/span><span style=\"font-weight: 400;\">component that can adjust single images well but performs very poorly for large-size images.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">That\u2019s why it is very essential to optimize images to improve the performance of your React Native application. Rendering multiple images will lead to high memory usage if the images are not properly optimized in terms of resolution and size. In some cases, the app can also get crashed due to memory overload.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some of the below-mentioned enhancements can be made to optimize images in a React Native application.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Instead of JPG format use the PNG format\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Use images that have smaller resolutions<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Lastly, you can also use the WEBP format to reduce the binary size of images on iOS and Android by almost one-third of the original size.\u00a0<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">In a nutshell, you should resize and scale down the image size before you load it into your application.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"4-Avoiding-Scroll-View-to-Render-Huge-Lists\"><\/span>4.
