About this PNG to WEBP converter

Convert PNG to WebP for smaller file sizes and faster loading on the web. Keeps quality with better compression. Ideal for websites and modern browsers.

What is a PNG file?

PNG (1996) is a lossless raster image format created as a patent-free replacement for GIF. It reproduces every pixel exactly, supports an alpha channel for transparency and up to 16 bits per channel, and compresses flat-colour areas very efficiently.

Strengths

  • Lossless, so text and line art stay perfectly sharp
  • Transparency (alpha channel)
  • Ideal for screenshots, logos, charts and UI graphics

Limitations

  • Photographs become 3 to 10 times larger than as JPG
  • No animation in common use (APNG is rare)
  • No native colour-management metadata in older files

Typical uses: Screenshots and diagrams; Logos and icons with transparent backgrounds; Images that will be edited again.

What is a WebP file?

WebP was released by Google in 2010 and is supported by every major browser since 2020. It offers lossy and lossless compression, transparency in both modes, and animation. Lossy WebP is typically 25 to 35 percent smaller than JPG at the same visual quality; lossless WebP is about a quarter smaller than PNG.

Strengths

  • Smaller files than JPG and PNG, so faster web pages
  • Transparency and animation in one format
  • Lossy and lossless modes

Limitations

  • Older desktop software and some upload forms still reject it
  • Not a good archive format: keep the original
  • Printing workflows generally expect JPG, PNG or TIFF

Typical uses: Images on websites and in web apps; Product photos and hero images; Animated stickers and short loops.

What changes when you convert PNG to WebP

Lossless mode keeps every pixel and typically saves about a quarter of the size; lossy mode saves far more and is fine for photographs. Transparency is preserved in both modes.
