Part 1. General Knowledge About HD Photo

If you're a pro photo editor, you already know that it's not easy to adjust a photo resolution manually, regardless of the image size. It even gets worse if you want to resize your image to a larger size because the result will be quite blurry. For instance, if a client gives you a small photo of 500 x 500 at 72dpi to resize it to 4000 x 4000 at 300dpi, the result might not be as good as you want.

In short, making a higher definition photo might not be that simple if you don't have the right tools. In most cases, only digital cameras can shoot HD photos at 1920 x 1080 pixels. These photos should fit perfectly on a widescreen like HDTV for full-screen viewing.

Fortunately, you can convert pictures to high-resolution quality easily using a third-party app, as I will show you in this article.

Part 2. Best Way to Convert Picture to HD You Should Know

If you want to batch process some pictures into a unified format, you can click the Select All on the upper displaying tab. Then click the Convert all images to choose an output format and click on the Gear icon on the top-right corner to choose an output quality.
