Frequently Asked Questions

Why convert PNG to JPG?

JPG files are 70-90% smaller than PNG for photos and complex images. Convert PNG to JPG to reduce file sizes for web use, email attachments, faster uploads, or saving storage space. JPG is also more universally compatible with older software and devices.

Will I lose quality?

Some quality loss with JPG compression, but it's minimal at high settings. At 90-95% quality, the difference is nearly invisible. For photos and complex images, this tradeoff is worth it for dramatically smaller files. For graphics with transparency or text, keep PNG.

What happens to transparency?

JPG doesn't support transparency. Transparent areas will be replaced with a solid color (usually white or black). If you need transparency, keep PNG or convert to WebP. Use PNG to JPG conversion only for images where transparency isn't needed.

Can I control the quality?

Yes! Choose quality from 60% (small files, visible loss) to 100% (large files, minimal loss). Recommended: 85-90% for web, 90-95% for high quality. Diwadi shows estimated file size before conversion.

Can I batch convert folders?

Absolutely! Select entire folders and convert thousands of PNG files to JPG in one operation. Perfect for optimizing photo libraries, website images, or product catalogs. Much faster than online tools.

When should I use JPG instead of PNG?

Use JPG for photos, complex images, backgrounds, and anywhere file size matters. Use PNG for logos, icons, graphics with text, screenshots, images with transparency, and images needing lossless quality.

How much smaller will JPG files be?

Typically 70-90% smaller. A 5MB PNG photo often becomes 300-500KB JPG at 90% quality. Exact savings depend on image complexity and quality settings. Simple graphics save less than photos.

Is PNG to JPG conversion free?

Completely free with unlimited conversions. No file limits, no watermarks, no credit card required.
