An Image Converter is a kind of file converter that converts one image file format (like jpg, bmp, tif, etc.) into another format. Whether you’re designing a website, writing a blog post, or sharing your latest photography shots, sometimes you’ll find yourself with a handful of images that need to be processed and converted. There are plenty of image converter tools out there, but many of them require a long installation process, and most are limited to one particular operating system.
Online Image Converters are a good solution if you want to escape that lengthy process to convert your images. Unlike with the installable image converter programs which mostly supports Windows and macOS, the online image converters can be used on any operating system that has a web browser. In a lot of cases, it’s just faster and more convenient to use free online tools because they’re accessible from anywhere at any time.
Online image converter software plays their crucial role by converting an image into any desired format on a day-to-day basis. Not just converting formats, an image converter software is also capable of tweaking image attributes, such as color, quality, brightness, contrast, etc. There are loads of image converter tools available online, so we decided to refine this list by comparing and picking the best ones for you.
