Does compressing PNG preserve transparency?

Yes! Our compressor fully preserves the alpha transparency channel in your PNG images. All transparent and semi-transparent areas remain intact.

What is lossless vs lossy PNG compression?

Lossless compression reduces file size without any quality loss by optimizing the encoding. Lossy compression reduces the color palette and applies quantization for much smaller files with minimal visible difference.

How much can PNG files be compressed?

Typical PNG compression reduces file sizes by 40-80% depending on the image content. Simple graphics with few colors compress more than complex photographs.

Should I convert PNG to JPG instead?

If your image does not require transparency, converting to JPG will usually result in smaller files. However, for graphics, text, screenshots, and transparent images, PNG is the better choice.

PNG is one of the most widely used изображение formats, known for graphics with transparency, logos, screenshots, text-heavy изображения. PNG uses lossless compression and supports full transparency, making it ideal for logos and graphics. However, PNG files can still be larger than necessary for web, email, and mobile use. Our specialized PNG compressor analyzes each изображение individually and applies format-specific optimization techniques that go beyond basic качество reduction. The engine considers color distribution, spatial detail, transparency channels, and content type to find the smallest possible размер файла at your chosen качество level. Whether you are optimizing PNG files for a website, preparing them for email, or reducing storage consumption, our tool delivers the best compression ratios available. Загрузить single files or process entire batches — all compression runs locally in your browser for complete privacy. No signup, no watermarks, no limits.
