Part 1. How to Choose the Best JPG Converter? 6 Things You Must Know

In selecting a JPEG image converter, you must know first that there are guidelines you must follow before selecting the converter of your choice. Here, we enlist the most common things that a user should look over and not overlook to have the best converter on hand to use in converting the JPG or JPEG format.

1. Price or Cost

Since there are different types of converters to use, there are some converters you will need to purchase before you can use them. Determining the price of the converter can be a significant factor that you can use as a baseline for the app you are about to download or use. Sometimes, a free converter can perform well, like what a paid converter can provide you.

2. Platform Supported or Availability on Operating System

Now that you have selected the converter you want to use, there is no exemption to see where these JPG creators or converters are available. Inspecting the availability of the program is essential because only some Windows-supported apps are available on Mac, or vice versa. Even if you have downloaded the file for the app, you wouldn't be able to install it when your OS isn't supported by the file or the tool itself.

3. Input File Size Limitation

Even though the JPG or JPEG uses lossy compression, there are times that its file size will go over the board, which means the more detailed the image is, the larger its final file size. However, you can compress JPG to lower the file to upload it on the app. Look for the input file size and the JPG or JPEG file that you are about to convert, then compare if the file size will fit precisely the restriction of the app.

4. Batch Processing or Batch Converting

Batch converting is essential; why? It helps users to convert multiple JPGs into one go. It helps users to alter JPG images simultaneously instead of placing them one by one on the app they are about to use. So, if you have more than 2 JPG and want to process them all in a one-uploading only, then it is better to look if the converter you are about to use supports batch converting.

5. Final Output Formats

Your choice of JPG maker or converter must support the final output format you desire the most. There has been an incidence that the converter of a user choice doesn't support the final output that they want to have. So, before you process the image on the converter, you need to check if the final output you want is available on the list of the things it supports.

6. Advance Settings for Quality Control

Changing the quality of a JPEG can be beneficial for the users since you can change the final output quality. This way, you can quickly improve the JPEG image quality when needed, but not every converter supports advanced settings. Even though the app doesn't have advanced settings, you still need to make sure that the app doesn't reduce the final output quality.
