Frequently Asked Questions

What's the difference between PNG and JPG formats?

PNG uses lossless compression and supports transparency, making it ideal for graphics and logos but resulting in larger files. JPG uses lossy compression without transparency support, creating smaller files perfect for photographs and web images where file size is important.

Will I lose image quality when converting PNG to JPG?

JPG uses lossy compression, so some quality loss is inevitable. However, our quality slider lets you control the compression level. Settings above 80% maintain excellent visual quality while significantly reducing file size compared to PNG.

How does the tool handle transparent backgrounds in PNG files?

Since JPG doesn't support transparency, our converter replaces transparent areas with your chosen background color. You can select white, black, or any custom color using the color picker to match your design needs.

Can I convert multiple PNG files at once?

Yes! Our tool supports batch conversion. Simply select multiple PNG files, adjust your quality and background settings, and convert them all simultaneously. Each file will be processed with the same settings for consistency.

What quality setting should I use for web images?

For web images, we recommend 80-85% quality for the best balance of file size and visual quality. For thumbnails, 60-70% is sufficient. For high-quality images where file size is less important, use 90-95%.

Is it safe to use this converter? Are my images uploaded anywhere?

Absolutely safe! All image processing happens entirely in your browser using HTML5 Canvas. Your images are never uploaded to our servers or any external service. The conversion is performed locally on your device, ensuring complete privacy.

Why are my converted JPG files sometimes larger than the original PNG?

This can happen with simple graphics or images with few colors at high quality settings. PNG is more efficient for simple images, while JPG excels with complex photographs. Try lowering the quality setting or consider keeping the PNG format for simple graphics.

Can I convert JPG back to PNG using this tool?

This tool specifically converts PNG to JPG. For JPG to PNG conversion, you would need a different converter. However, note that converting JPG to PNG won't restore any quality lost during the original PNG to JPG conversion.
