The two most common reasons that people need to resize images are to use on a website and for posting on social media. Keep reading to learn how to resize an image without losing quality.
Can You Resize an Image Without Losing Quality?
Regardless of the reason, there will be times when you need to resize an image stored either on your phone or computer. That’s when you need to know how to resize an image quickly and easily.
Not all image formats are created equal. Some types, like GIFs, are older and support fewer colors. BMP is a Microsoft format, and those files can get very large. PNGs and JPEGs are optimal choices for the web because they support millions of colors and can be stored in relatively small files sizes without losing any quality. Additionally, PNG files support transparency, which is a must for website developers. TIFF is a high-quality format great for print and versatile enough to store multiple images in one file.
When resizing images, keep in mind that GIFs and JPEG formats are “lossy” and will lose some quality. Whereas PNGs, BMP, TIFF, and SVG files will not lose quality. A rule of thumb to keep in mind is that raster files (like GIF, JPEG, and even some PNGs) will lose some quality when resized or re-formatted but vector images like SVGS, AI, and XPS will not. They can be sized up or down without any loss of quality. Graphic designers create logos using vector images so they can be increased or decreased in size for different purposes.
Generally, if you take a large image and make it smaller, you will not lose any visible quality. However, if you try to take a small picture and stretch it larger, it will appear blurry and pixelated.
For websites, the human eye can only perceive a certain density of quality and so web graphics and images don’t need to be that high quality (only about 72 DPI). Print images and logos; however, do need to be at least 300 DPI (dots per inch).
