About Image Format Conversion

Converting between image formats is essential for optimizing files for different uses. Each format has its advantages: some are better for photos, others for graphics with transparency, and some offer better compression. Our tool processes everything in the browser, ensuring complete privacy.

Supported Formats

  • JPEG: Ideal for photos. Offers good compression but doesn't support transparency.
  • PNG: Perfect for graphics and images that need transparency. Lossless compression.
  • WebP: Modern Google format with excellent compression and transparency support.
  • GIF: Limited to 256 colors. Mainly used for simple animations.
  • BMP: Uncompressed format. Large files but no quality loss.

When to Convert

Convert to WebP when you want smaller file sizes for web. Use PNG for logos and graphics that need transparency. JPEG is ideal for photographs. Avoid converting lossy images (JPEG, WebP) multiple times, as each conversion can degrade quality.

Usage Tips

For best quality, always keep a copy of the original file. When converting from PNG to JPEG, transparent areas will be replaced with white. WebP is the most versatile format, offering small sizes with good quality, but check browser compatibility for older websites.
