How to Convert PNG to JPG

PNG is lossless and supports a full alpha channel for transparency, which makes it ideal for screenshots, graphics, and logos, but that same lossless storage means PNG files are often considerably larger than a JPG of the same photographic image. JPG's lossy compression discards some image data on save in exchange for a much smaller file, which is exactly what you want when you need to email, upload, or store a large batch of PNG photos without the extra bulk.

The tradeoff to keep in mind is transparency: JPG has no alpha channel at all, so any transparent areas in your PNG files will be filled with a solid background color during conversion, which is worth checking before converting graphics or logos that rely on a transparent background.

1. Install Batchify Image Converter and Resizer Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single PNG.
3. Drag your PNG file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to PNG and the "To" format to JPG.
5. Adjust the JPG quality slider to balance file size against image clarity.
6. Click Convert. JPG files are written to the output folder, fully offline.
