Open your web browser and go to an online image converter website. You can use a reputable service like OnlineConvertFree, Convertio, or Zamzar.
Look for an option to upload or select your JPG image. Typically, you’ll find a button that says “Upload” or “Choose File.”
Use the file picker dialog to locate and select the JPG image you want to convert from your computer.
After selecting the file, you may be asked to choose the output format. In JPG to PNG this case, select “PNG” as the output format.
Start the conversion process. This is usually done by clicking a “Convert” or “Start” button on the website.
Wait for the conversion to complete. The time it takes may vary depending on the size of the image and the speed of the conversion service.
Once the conversion is finished, you should see a download link for the converted PNG image. Click the link to download the PNG file to your computer.
