Benefits

  • Transparency Preserved: Unlike JPG compression, PNG compression keeps your transparent backgrounds fully intact, which is critical for logos, overlays, and design assets.
  • Better Web Performance: Smaller PNG files load faster on websites, reducing bandwidth usage and improving user experience for image-heavy pages.
  • Lossless Option Available: Choose lossless compression to reduce file size without changing a single pixel, perfect for preserving exact image data in design workflows.
  • Metadata Cleanup: Optional removal of unnecessary PNG metadata and colour profile data further reduces file size without affecting visual appearance.

Who Can Benefit

  • Web Designers: Compress PNG icons, UI elements, and graphics before adding them to websites to maintain crisp visuals with smaller file sizes.
  • Graphic Designers: Optimise PNG exports from design software for client delivery, portfolio uploads, and digital asset management with reduced file sizes.
  • App Developers: Reduce PNG asset sizes in mobile and web applications to minimise app download sizes and improve loading performance.
  • Digital Marketers: Compress PNG graphics for social media posts, banner ads, and landing pages to ensure fast loading across all platforms.

Why Choose This Tool
