Image Format Converter Tutorial

Why Convert Image Formats?

Different image formats serve different purposes. JPG is ideal for photographs with its small file size, PNG preserves transparency for logos and icons, WebP offers the best of both worlds with modern compression, and ICO is required for website favicons. Converting between formats lets you optimize images for web performance, print quality, or application compatibility.

How to Use

  1. Upload your image (PNG, JPG, WebP, BMP, TIFF, or ICO)
  2. Choose the target format from the dropdown
  3. Adjust quality for JPG/WebP (higher = better quality, larger file)
  4. Optionally set new dimensions to resize
  5. Click "Convert Image" and download the result

Format Comparison

  • PNG: Lossless, transparency, best for graphics
  • JPG: Lossy, no transparency, best for photos
  • WebP: Modern, both lossy/lossless, smaller files

Quality Tips

  • 85-95: High quality, slight compression
  • 60-80: Good balance of quality and size
  • 30-50: Aggressive compression, visible artifacts

Alpha Channel

  • PNG, WebP, TIFF, ICO support transparency
  • JPG and BMP do not — transparent areas become white
  • ICO auto-generates standard sizes (16-256px)
