Short Comment

Upscale Media is a good online AI image upscaler, but it still has some drawbacks. First is the file size limitation. Second, when I click the Upload button on the home page, I actually open and use a new webpage that has a big ad. At last, I personally think that the uploading and processing speed is not that fast, and I failed to upload the test image it offers.

Part 2. How to Enhance JPEG Resolution with Adobe Photoshop

Most image content creators must be very familiar with Adobe Photoshop. It is one of the most powerful images editing software. You can almost finish all image editing with this software, from simple cropping and resizing to complicated layer mixing and editing. Of course, it can also be used as an image upscaler. Here are the detailed steps to enlarge JPG image with Photoshop.

Step 1. Download and install Adobe Photoshop from the official website.

Step 2. In the interface, click File on the top menu and choose Open to load the image you want to improve.

Step 3. To resize the image, you can go to Image › Image Size or press Crtl+Alt+I on your keyboard.

Step 4. The Image Size window will pop up. You need to activate Resample and we recommend you choose Bicubic Smoother (enlargement) in the drop list.

Step 5. To adjust the Resolution, you can add new values to the Width and Height options. Click OK and Photoshop will process automatically.

Step 6. Click File > Save As to rename your new image and choose the destination and format to save it.

Photoshop is fast to make high resolution JPEG because it uses its inner program to scan and resize the image. You don’t even need to connect to the internet. But Photoshop has a very complicated interface and it will slow down the computer.
