Launch PhotoWorks and open the image you want to resize. Your images won't get all fuzzy and blurred even after significant reduction. This image resizer features several resizing presets that offer optimal dimensions and settings for your purpose (social sharing, an HD photo movie, etc.).
Need to resize an image quickly and easily? Try PhotoWorks, a smart photo editor. Let's take a closer look at them, so that you could choose the perfect tool for your needs. The best programs use bicubic interpolation to achieve maximum quality and clarity of the resulting image. There are other image scaling algorithms, but we won't describe them here, because most resizing tools use the three ones we've just listed. You get a sharpened image that is very close to the original one. It is the most effective algorithm, which calculates the color on the basis of 16 nearest pixels. The resulting quality is higher, but the image can lose in saturation and fine details.īicubic interpolation. It calculates the average value of 4 pixels around a certain point. The processing speed is high, but color fidelity leaves much to be desired.īilinear. It uses only the value of the nearest pixel to calculate the color of a certain point. There are three most popular algorithms of interpolation: Reduce its quality using interpolation (color change).Lower the resolution of a photo (reduce the number of pixels).If you need to reduce the image size, you can use one of the three methods: On the contrary, PNG uses a lossless compression algorithm, so the resulting file size is bigger. Image quality also depends on the format: JPEG is a lossy one that can drastically shrink the picture size. But bitmap images, such as photos, should be resized with the help of advanced algorithms to keep fine details and avoid blurriness. Logos and other vector images can be scaled up or down without any harm. If you resize (reduce or enlarge) an image, you just change its factual size and the number of pixels, while keeping all the visual information. When you crop an image, you simply cut out its part. First, you shouldn't confuse resizing and cropping. Detailed instructions and screenshots will help you sort out the resizing process in no time! What Is Image Scaling and How It Works? What's more, you will get acquainted with 5 excellent resizers for different operating systems. Keep on reading this guide and you will learn what methods and algorithms work best to resize an image and keep high quality.
