Resizing JPG Images Online

An image’s aspect ratio and resolution directly affect the visual perception of your project. For example, distorted, stretched pictures look displeasing, while well-defined, proportional images attract attention. That’s why digital creators manipulate and adapt visuals in graphics editors. And this process often includes resizing. But what can you do if you are just starting out and know nothing about editing? 

Simple, user-friendly online tools can easily change image size and improve quality. You don’t need in-depth design skills to master them, while automated picture processing takes only a few seconds. In this article, you’ll find three online tools suitable for the task. Keep reading! 

Why do you need to resize your pictures?

Different online sources and design projects might pose specific technical requirements for photos. For example, the optimal image size for Facebook posts is 1200x630px. And if your picture is bigger than 2048x2048px, the platform will automatically decrease its quality. When posting photos on Instagram feed, you must fit into 1080x1350px; otherwise, the system will crop some of your image parts.

Designers and online creators often use multiple social media platforms to build their content marketing. Therefore, they need to be familiar with the requirements of each platform and be able to adapt their visuals to a specific source.

How to resize your image online 

The easiest way to rescale pictures and boost their resolution is to use web-based resizers that provide simple and user-friendly functionality. Just upload your file, set new dimensions, and get the result. To ensure your picture format changes proportionally and the number of pixels doesn’t decrease, use AI-powered upscalers. Besides automated resizing, they also enhance your image quality and fix defects.
