Image Format Comparison
Different image formats serve different purposes. Understanding when to use each can dramatically improve your website's performance and your images' quality.
| Format | Best For | Transparency | Compression |
|---|---|---|---|
| PNG | Logos, icons, screenshots, graphics | Yes | Lossless |
| JPEG | Photos, web images, social media | No | Lossy |
| WebP | Modern web images, all-purpose | Yes | Both |
| BMP | Legacy applications, raw image data | No | None |
| TIFF | Print, archival, professional photography | Yes | Both |
For web use, WebP is the modern standard — it provides the best compression efficiency and supports both lossy and lossless modes with transparency. JPEG remains the most widely compatible format for photographs. PNG is ideal when you need pixel-perfect lossless quality. This converter can open the formats your browser can display and saves PNG, JPEG or WebP; it does not save TIFF.
