image format converter

Convert images between PNG, JPG, WebP, and other formats.

An image format converter allows you to change image file formats to meet specific requirements for websites, applications, or compatibility needs. This tool is essential for web developers, graphic designers, content creators, and anyone who needs to convert images between different formats like PNG, JPEG, and WebP. By converting formats, you can optimize file sizes, ensure compatibility with different platforms, preserve transparency when needed, and meet specific technical requirements. The tool processes images entirely in your browser, ensuring privacy and instant results without uploading files to external servers.

What is image format converter?

Image format conversion is the process of changing an image file from one format to another, such as converting PNG to JPEG or JPEG to WebP. Different formats have different characteristics: PNG supports transparency and is lossless, JPEG offers smaller file sizes with lossy compression, and WebP provides modern compression with transparency support. This online converter uses HTML5 Canvas technology to process images client-side, meaning all conversions happen in your browser without server uploads. You can adjust quality settings for JPEG and WebP formats to balance file size and image quality.

Common use cases

  • Web optimization: Convert images to WebP format for better compression and faster website loading
  • Transparency preservation: Convert images to PNG when transparency is required for logos or graphics
  • File size reduction: Convert PNG images to JPEG for smaller file sizes when transparency is not needed
  • Platform compatibility: Convert images to formats required by specific platforms, applications, or devices
  • Print preparation: Convert images to appropriate formats for printing requirements
  • Legacy system support: Convert modern formats to older formats for compatibility with legacy systems

Limitations and common mistakes

  • Converting from lossy formats (JPEG) to lossless formats (PNG) does not restore original quality lost during previous compression
  • Converting PNG with transparency to JPEG will result in a solid background color, losing transparency information
  • Some advanced image features like animation (GIF) or multiple layers may not be preserved during conversion
  • Very large images may take longer to process, and browser memory limits may restrict maximum file sizes
  • Quality settings for JPEG and WebP are lossy, meaning some image data is permanently discarded during conversion

Frequently Asked Questions

Which image formats are supported?

You can convert images to PNG, JPEG, or WebP formats. The tool supports all common input formats including PNG, JPEG, GIF, WebP, and BMP. Conversion happens entirely in your browser.

Is conversion lossless?

PNG conversion is lossless, maintaining original quality. JPEG and WebP conversions are lossy, meaning some quality is sacrificed for smaller file sizes. You can adjust quality settings for JPEG and WebP to balance size and quality.

Can I convert between all formats?

Yes, you can convert from any supported image format to PNG, JPEG, or WebP. The conversion happens automatically when you select a target format.

What happens to transparency when converting?

PNG supports transparency, which is preserved when converting to PNG. When converting PNG to JPEG, transparency is lost and replaced with a solid background. WebP supports transparency and preserves it when converting from PNG.

Does the tool reduce image quality?

For PNG, quality is always maintained as it is lossless. For JPEG and WebP, you can adjust quality settings. Lower quality results in smaller files but may show compression artifacts. Higher quality preserves more detail but creates larger files.

Is my image data secure?

Yes, all processing happens in your browser. Images are never uploaded to any server, ensuring complete privacy and security of your files.
