| Feature | PNG (Portable Network Graphics) | JPG / JPEG |
|---|---|---|
| Compression | Lossless (no quality degradation) | Lossy (adjustable compression ratio) |
| Transparency | Supports alpha channel transparency | No transparency support (solid background required) |
| Typical File Size | Larger (especially for complex photographs) | Significantly smaller (ideal for websites & emails) |
| Best For | Logos, screenshots, UI icons, sharp diagrams | Photographs, digital art, social media uploads |
Important note regarding transparency in JPG files:
Because the JPEG specification cannot store transparent pixels, transparent areas in your PNG image will be automatically filled with your chosen background color (default is pure white). If you require background transparency for web design, keep your files in PNG or convert them to WebP.

PNG uses lossless compression, whereas JPG is a lossy compression format. While converting reduces file size, setting the quality to 85%–95% preserves virtually identical visual appearance for everyday photos, web graphics, and screenshots.
