To convert a PNG file to the JPG format, first download and install an image viewer that’s capable of converting image files, such as IrfanView. Then, open the PNG file in the program, and save the file in JPG format. Alternatively, use an online file conversion service, such as Zamzar.
To use IfranView, first navigate to IrfanView.com, and click on the Download link before selecting your desired download location. Double-click on the executable file once the download is complete, and follow the on-screen instructions to finalize the installation process. After starting the program, click on the File option in the navigation bar, and click Open before double-clicking on the PNG file you want to convert. Make any changes to the file if necessary before selecting the Save As option from the File menu, and select the JPG option from the drop-down menu in the Save As Type section. In the JPEG/GIF Save Options window, select the desired quality and file size before clicking Save.
To convert the PNG file using an online service, first navigate to Zamzar.com, and click on the Choose Files button before selecting the PNG file and clicking on Open. Choose the JPG option from the Image Formats section of the drop-down menu, and enter your email address in the appropriate field before clicking on Convert. Once the conversion process completes, download the converted file from the message that Zamzar.com sends to your email address.
