What Does This PNG to JPG Converter Do?
This tool converts PNG images to JPG format directly in your browser. Because JPG does not support transparency, any transparent pixels in your PNG are filled with a background color you choose before the image is encoded as a JPG.
The result is a smaller file that is easier to share, embed, or print, while keeping you in control of how transparent areas look in the final image.
How to Convert PNG to JPG
- Drop one or more PNG files onto the drop zone, or click Browse Files.
- Pick a background color for transparent areas - a preset swatch or a custom color.
- Adjust the JPG Quality slider if needed.
- Click Convert - results appear in the list with size and change info.
- Use the preview button on any row to compare the original PNG and converted JPG side by side.
- Download images individually or grab them all as a ZIP.
Why the Background Color Matters
PNG supports an alpha channel, so logos, icons, and graphics often have transparent backgrounds. JPG has no transparency support - every pixel needs a solid color. If you skip this step, transparent areas typically default to white, which can look wrong on a colored page or when the image is later placed on a different background.
Choosing white works well for documents and print. Black suits dark themes. Matching your website or brand color keeps the flattened image blending in seamlessly wherever it's placed.
How the Quality Slider Works
The quality setting (1-100) controls the lossy compression level applied during conversion:
- 85-95 - Best for most use cases. Excellent visual quality with solid size savings over PNG.
- 60-84 - Good for thumbnails or previews where file size matters most.
- 96-100 - Near-lossless, useful for images that will be printed or re-edited.
- Below 60 - Noticeable compression artifacts, only suitable for small decorative images.
Batch Conversion and Side-by-Side Preview
Drop as many PNG files as you like - each gets its own row with independent status, size, and download controls. Every file uses the same background color and quality setting, so you can process a whole folder of icons or graphics in one pass. The preview panel lets you check exactly how the transparent areas were filled before you commit to downloading.
Privacy & Security
Your images never leave your device. Conversion happens entirely inside your browser using the Canvas API - no files are uploaded to any server, no account is needed, and there are no usage limits.
Frequently Asked Questions
What happens to transparent parts of my PNG?
They are filled with the background color you select before the image is saved as a JPG, since JPG cannot store transparency.
Can I convert multiple PNGs at once?
Yes. Drop as many images as you like - each appears as a row in the list with its own preview and download button once converted.
Will converting to JPG reduce image quality?
At quality 85 and above, the difference is typically minor. JPG uses lossy compression, so very high quality settings keep results close to the original while still reducing file size.
Why is my JPG larger than the original PNG?
This can happen with small, simple, or mostly flat-color images. Try lowering the quality setting slightly, or keep such images as PNG if size is more important than format.
What happens to my images after I convert them?
Nothing - they stay on your device. This tool does not upload, store, or share any image data.
