Why use ConvertWiki?
Smaller PNG files without losing transparency
PNG is a strong choice for screenshots, interface images, logos, and graphics with transparency, but PNG files can become heavy quickly. Compression helps reduce file size while keeping the format compatible with design tools, websites, and documents.
The best results usually come from graphics with flat colors or large repeated areas. Detailed photos may compress less as PNG, so converting to JPG or WebP can be a better option when transparency is not needed.
Use this compressor for
- Reducing PNG screenshots before publishing or sharing.
- Keeping transparent graphics lighter for websites.
- Optimizing logos, UI captures, and simple product assets.
