What Is PNG to JPG Conversion?
This tool converts between PNG and JPG image formats in both directions. Use PNG when you need transparency and JPG when you want smaller files, and pick the format that fits the job.
Everything is processed in your browser, so your image data is never sent to any server. Batch conversion of multiple files is supported, so a whole folder of images can be converted in one go.
Whether you need to lighten images for the web by converting to JPG, keep logos and icons as PNG, or want a lossless PNG for further editing, this tool handles it. There is no sign-up or login, and it is free to use as often as you like.

PNG ⇔ JPG Converter FAQ
- Is my file sent to a server?
- No. All processing happens entirely in your browser. Your images are never uploaded to any external server, so private photos stay on your device.
- What happens to transparent areas when converting PNG to JPG?
- Since JPG does not support transparency, transparent areas are filled with the background color you choose (white to begin with). You can switch it to black or light gray under "Background (transparent areas)".
- What are the benefits of converting JPG to PNG?
- PNG uses lossless compression, so saving again does not degrade the image. It is ideal for re-editing text and logos that need to stay crisp, and it supports transparency.
- Will the image quality degrade?
- JPG → PNG conversion preserves quality as-is (though information already lost to JPG compression cannot be recovered). For PNG → JPG, choose a "JPG quality" preset: Standard suits most uses, and High quality keeps more fine detail.
- How many files can I convert at once?
- Select as many as you need and convert them in one go. There is no fixed cap on how many files or how large they are; it depends on your device's memory. There is no sign-up and no daily limit.
- Why is my screenshot so large?
- Screenshots are saved as PNG, which keeps every pixel exactly. Converting to JPG usually cuts the size dramatically with little visible change, though very fine text can soften slightly.
- Does converting JPG to PNG improve quality?
- No. PNG stores the image without further loss, but it cannot recover detail the JPG already discarded. Convert to PNG for compatibility or repeated editing, not to sharpen an image.
