Format Comparison
| Format | Type | Compression | Transparency | Animation | File Size | Notes | Convert |
|---|---|---|---|---|---|---|---|
JPG/JPEG | Raster | Lossy | ✗ | ✗ | Small (e.g., 200KB - 800KB) | Best for photos; quality loss with higher compression. Typical 1920x1080 photo. | Convert jpg |
PNG | Raster | Lossless | ✓ | ✗ | Medium (e.g., 1MB - 5MB) | Ideal for graphics, logos, images needing transparency. Medium size (e.g., 1MB - 5MB). | Convert png |
WebP | Raster | Both | ✓ | ✓ | Very Small (e.g., 150KB - 700KB) | Modern format, excellent balance of size and quality. Very small (e.g., 150KB - 700KB). | Convert webp |
GIF | Raster | Lossless | ✓ | ✓ | Medium (e.g., 500KB - 3MB for animation) | Good for simple animations and low-color images. Medium (e.g., 500KB - 3MB for animation). | Convert gif |
BMP | Raster | Lossless | ✗ | ✗ | Very Large (e.g., 6MB - 8MB) | Uncompressed, generally not recommended for web. Very large (e.g., 6MB - 8MB). | Convert bmp |
TIFF | Raster | Lossless | ✓ | ✗ | Large (e.g., 5MB - 10MB) | High-quality archival format, often used in print. Large (e.g., 5MB - 10MB). | Convert tiff |
AVIF | Raster | Both | ✓ | ✓ | Extremely Small (e.g., 100KB - 500KB) | Newer, highly efficient, still gaining broad support. Extremely small (e.g., 100KB - 500KB). | Convert avif |
HEIC | Raster | Both | ✓ | ✗ | Extremely Small (e.g., 100KB - 500KB) | Apple's format, excellent compression, good quality. Extremely small (e.g., 100KB - 500KB). | Convert heic |
SVG | Vector | Lossless | ✓ | ✗ | Tiny (e.g., 5KB - 50KB) | Scalable vector graphics, resolution-independent. Tiny (e.g., 5KB - 50KB). | Convert svg |

Start ConvertingFrequently Asked Questions
For modern websites, use WebP or AVIF for the best compression and quality. Always provide JPG or PNG fallbacks for older browsers. Use PNG for images requiring transparency, and JPG for photographs.
Lossy compression (JPG, WebP lossy) reduces file size by removing some image data, which may slightly reduce quality. Lossless compression (PNG, WebP lossless) preserves all original image data but results in larger files.
Newer formats use advanced compression algorithms that can achieve 30-50% smaller file sizes compared to JPG/PNG while maintaining the same visual quality. This means faster loading websites and reduced bandwidth usage.
Check the "Browser Support" column in our comparison table above. Universal formats work everywhere, Modern formats work in recent browsers, and Limited formats have specific browser requirements. Always test or provide fallbacks.
PNG is the universal choice for graphics with transparency. For modern browsers, WebP offers better compression with transparency support. SVG is ideal for simple logos as it's vector-based and scales perfectly.
It depends on your needs. Convert to WebP/AVIF if you want smaller file sizes for web use, but keep your originals. For print or archival purposes, stick with high-quality PNG or TIFF. Consider your audience's browser support before switching.
Yes! Our converter supports all the formats listed above. You can convert from any format to any other, though some conversions (like vector SVG to raster formats) will rasterize the image. Check the "Convert" links in the table for quick access.
Raster formats (JPG, PNG, WebP, etc.) store images as pixels and have fixed dimensions. Vector formats like SVG store images as mathematical descriptions of shapes, allowing infinite scaling without quality loss. Raster is better for photos, vector for logos and simple graphics.
For print: Use TIFF or high-quality PNG for maximum detail and color accuracy. For web: Use WebP or AVIF for modern browsers with JPG/PNG fallbacks. Consider HEIC for Apple ecosystems and SVG for scalable graphics.
Animated GIF and WebP are image formats with animation support, while MP4/WebM are true video formats. For short loops and simple animations, WebP animated files are smaller than GIF. For longer content or complex motion, convert to MP4 for much better compression.
