• JPG → PNG: Quality stays same (no improvement)
• PNG → PNG: Quality maintained
• JPG → JPG: Quality may decrease further

Q: When should I use WebP?

A: Use WebP for modern websites when:

• Target audience uses modern browsers
• File size is priority
• Need transparency or animation
• Want best quality/size ratio

Q: Can I convert multiple images at once?

A: Yes, use the Batch Conversion feature to convert multiple images with same settings.

Q: Why is my converted image larger?

A: Converting from lossy (JPG) to lossless (PNG) increases file size because PNG preserves all data.

Q: What's the best format for email?

A: JPG - widely supported, small files, perfect for email attachments.
