Why Convert Images?

Different image formats are built for different jobs. A PNG is perfect for logos with transparency, but a JPEG is often smaller and better for photographs on a website. A WEBP or AVIF file provides even better compression, making your website load lightning fast. This tool gives you the power to choose the right format for your needs.

Understanding the Formats

  • PNG (Portable Network Graphics): A lossless format (no quality loss) that supports transparency. Great for logos, icons, and text.
  • JPEG (or JPG): A lossy format (some quality is lost) that is excellent for photographs. You can control the quality to get a very small file size.
  • WEBP: A modern format from Google that offers superior lossless and lossy compression compared to PNG and JPEG. Widely supported.
  • AVIF: The newest format, offering even better compression than WEBP. Perfect for performance-focused websites.
  • BMP (Bitmap): An old, uncompressed, and lossless format. Files are very large and not recommended for web use.

Frequently Asked Questions (FAQ)

Is this image converter safe to use?

Yes. This is the safest possible way to convert images because your files are never uploaded to a server. The entire conversion process happens locally on your computer using your web browser.

Will I lose quality when converting?

It depends on the format. Converting from a JPEG to a PNG will not add quality. Converting from a high-quality PNG to a low-quality JPEG will result in quality loss (but a smaller file). For best results, always start with the highest quality image you have.

Why does my PNG with transparency get a white background?

Formats like JPEG (JPG) and BMP do not support transparency. When you convert a transparent PNG to one of these formats, a white background is automatically added to fill the transparent areas.
