Convert PNG to JPG Online

PNG images provide exceptional graphical fidelity and transparency support, but uncompressed screenshots and photographs in PNG format often result in huge file sizes. Converting PNG to JPG reduces storage payloads by up to 80% while ensuring seamless compatibility with web portals, emails, and photo galleries.

PNG Format (Lossless & Alpha)

PNG preserves 100% of pixel data and supports alpha transparency. Ideal for vector logos, UI icons, and technical diagrams, but produces large file sizes for photographs.

JPG Format (Compact & Universal)

JPG uses discrete cosine transform lossy compression to dramatically reduce photo file sizes. Supported by every web browser, operating system, and image viewer worldwide.

Transparency Flattening Explained

Because JPEG format does not have an alpha transparency channel, transparent pixels are composited onto a solid background (white by default, or your chosen custom color).

Adjustable JPEG Compression

Our quality slider controls the JPEG quantization matrix directly. Setting quality to 85% achieves optimal compression with zero visible degradation to the naked eye.
