Convert to PNG with smart quality-size balance, real-time preview, batch processing

All image processing is done locally in your browser via WebAssembly, ensuring privacy. Conversion supports custom quality, smart compression, batch processing, real-time before/after comparison, and one-click download to optimize image loading and transfer efficiency.

  • Why convert to PNG?

    JPG, HEIC, and most other formats do not support transparency, making them unsuitable for icons and design assets. Convert to PNG to unlock transparency, meeting design upload requirements across all platforms with clear, stable visuals.

  • What is PNG?

    PNG (Portable Network Graphics) is a lossless image format supporting transparency, indexed color, and true color. Widely used for icons, logos, UI design, and transparent assets requiring pixel-perfect preservation.

  • Why compress PNG?

    PNG files are often large, slowing page loading and consuming storage and data. Proper compression significantly reduces file size while preserving transparency and clarity, improving load speeds and meeting platform upload limits.

  • How does PNG compression work?

    PNG supports both lossless and lossy compression. Lossless compression reduces size through data optimization, palette reduction, and filtering algorithms without losing any pixels. Lossy compression can moderately reduce color count and optimize channel data for higher compression ratios while preserving transparency with no visible difference.
