Convert Between JPG, PNG and WebP

Different image formats serve different purposes. This tool supports conversion between JPG/JPEG, PNG and WebP, so you can choose a format that fits your intended use.

  • JPG/JPEG: Commonly used for photographs and everyday image uploads.
  • PNG: Useful when you need to retain transparency or work with graphics that benefit from it.
  • WebP: A modern web image format that supports lossy and lossless image encoding, including transparency.

You can convert JPG to PNG, PNG to JPG, JPG to WebP, WebP to JPG, PNG to WebP and WebP to PNG. The output format determines which image characteristics can be retained. For example, JPG does not support transparency.

Adjust Image Quality Where Supported

The best conversion settings depend on the output format and how you plan to use the image. For JPG and WebP output, use the available quality slider to balance visual appearance and file size. Higher quality settings generally preserve more image detail, while lower settings may create smaller files with more visible compression.

PNG uses a different encoding compression setting. Its compression level is not the same as the JPG/WebP quality scale.

Changing an image's format does not guarantee a smaller file. The resulting file size depends on the original image, output format, image content and selected settings. Check the converted result before using it.

Understand Transparency and Image Dimensions

PNG and WebP can retain transparency when the selected conversion and source image support it. JPG cannot store transparent pixels, so transparent areas become white when an image is converted to JPG using this tool.

Image conversion with iToolsEra preserves the original pixel dimensions. It changes the file format rather than resizing the image. If you need different width or height values, use the separate Image Resizer tool.
