Javascript image resize library8/9/2023 ![]() then(b64 => document.querySelector('img').src = b64) Then you can use this code to generate a simple image: //write this inside of your javascript file Install the library itself: npm install -save merge-images Or you can find this library helpful for personal use, for example, combining a few different images to generate a collage. For example, you can generate an NFT Collection where you can merge all components to have a complete set of variations. It’s a valuable library that can help with several tasks. You can also create parameters like positioning, opacity, and several more. It's a wrapper around the Canvas API, abstracting its low-level functions, which makes this specific task a lot easier. Merge Images abstracts all repetitive tasks into simple function calls. ![]() Working with the canvas can be slightly tedious, especially when you need the canvas context to do relatively simple things like merging a few images. This library can be installed with the following command: npm install cropperjsĬonst image = document.getElementById('image') Ĭheck out the Cropper.js demo, click on any property that you want to apply to your image and see the result instantly.įor an in-depth guide on how to add image cropping to your React app, check out our guide on using react-image-crop. It will be more efficient because it requires almost nothing, doesn’t have any useless features, and is very optimized for cropping! Example You can use its flexible API to create a custom image cropping UI in your web app allowing your users to adjust photos to the correct size and aspect ratio. Cropper.js is the right choice for cropping without any extra features. You can use it to crop your images in all possible ways, change aspect ratio, rotate, zoom and work with canvas data. This is how you would resize an image using sharp: const sharp = require('sharp') Ĭropper.js is another popular JavaScript library for image manipulation. You can install this library by using the command below: npm install sharp So again, if you would like to use it for resizing several large images, then it’s the best choice for you - you’ll do it in the fastest and most efficient way. I used it to resize a whole NFT Collection with a size of over 80Gb, which after compression came out at circa 10Gb. Sharp is taking full advantage of multiple CPU cores and L1/L2/元 cache, allowing you to resize and compress your images much more quickly. Instead, ordinary HTML and vanilla JavaScript will be more beneficial. If, on the other hand, you only want to resize a single small image, then you probably shouldn’t use it. Sharp is helpful only if you want to resize a giant file or a variety of them. The typical use case for this high-speed Node.js module is to convert large images in standard formats to smaller, web-friendly images. Sharp is a high-performance Node.js image processing library to resize different image formats such as JPEG, PNG, WebP, AVIF, SVG, and TIFF. To finish up, we wandered into the realm of testing images, since no image manipulation application is complete without a reliable way to test results. We have included libraries for every significant image manipulation task, from simple, low-level operations such as filters, brightness, and saturation to single-purpose libraries for cropping or image composition. ![]() Image Manipulation Libraries (IML) are used to perform various manipulation functions on images: you can increase the brightness of an image, add saturation or filters, crop and resize, and more valuable features that will help you to do almost everything and turn your web browser into an Adobe Lightroom! ![]()
