The Image Format Landscape
Choosing the right image format affects file size, quality, compatibility, and features like transparency and animation. This guide covers every major format you will encounter.
Format Comparison Table
| Format | Type | Compression | Transparency | Animation | Best For |
|---|---|---|---|---|---|
| JPG/JPEG | Raster | Lossy | No | No | Photographs |
| PNG | Raster | Lossless | Yes | No (APNG: Yes) | Screenshots, logos |
| WebP | Raster | Both | Yes | Yes | Web images (all types) |
| AVIF | Raster | Both | Yes | Yes | Web images (max compression) |
| SVG | Vector | N/A | Yes | Yes | Icons, logos, illustrations |
| GIF | Raster | Lossless (256 colors) | Yes (1-bit) | Yes | Simple animations |
| TIFF | Raster | Both | Yes | No | Print, photography |
| BMP | Raster | None/RLE | Limited | No | Legacy Windows |
| ICO | Raster | Lossless | Yes | No | Favicons |
| HEIC/HEIF | Raster | Lossy | Yes | Yes | Apple device photos |
JPG/JPEG
The most widely used image format on the web. JPG uses lossy compression optimized for photographs, achieving 60-80% size reduction with minimal visible quality loss.
Strengths: Universal support, excellent for photos, small file sizes Weaknesses: No transparency, lossy only, degrades with re-saving Use when: Displaying photographs on any platform
PNG
The standard for lossless raster images on the web. PNG supports full alpha transparency and preserves every pixel perfectly.
Strengths: Lossless quality, full transparency, great for text/screenshots Weaknesses: Large file sizes for photos, no native animation Use when: Screenshots, logos over backgrounds, images requiring transparency
WebP
Google’'s modern format that supports both lossy and lossless compression, transparency, and animation — essentially replacing JPG, PNG, and GIF in a single format.
Strengths: 25-35% smaller than JPG, 20-30% smaller than PNG, 97%+ browser support Weaknesses: Slightly slower encoding than JPG, not universally supported in email clients Use when: Any web image — it is the current best all-around format
Convert with our JPG to WebP or PNG to WebP tools.
AVIF
The newest major web format, based on the AV1 video codec. AVIF delivers the best compression ratios available.
Strengths: 40-50% smaller than JPG, HDR support, 10/12-bit color Weaknesses: Slow encoding, 92% browser support, limited tool support Use when: Maximum compression matters, photograph-heavy pages
Convert with our JPG to AVIF or PNG to AVIF tools.
SVG
A vector format that describes images as mathematical shapes in XML. SVG files are resolution-independent and often tiny for simple graphics.
Strengths: Infinite scalability, tiny file sizes for icons, editable with code, CSS-stylable Weaknesses: Not suitable for photographs, complex SVGs can be large and slow to render Use when: Icons, logos, illustrations, charts, maps
Convert vectors to raster with our SVG to PNG tool.
GIF
The oldest web image format still in common use. GIF is limited to 256 colors but supports animation, making it the original meme format.
Strengths: Universal support, animation, simple implementation Weaknesses: 256 color limit, large animated file sizes, 1-bit transparency only Use when: Simple animations where WebP/AVIF animation is not supported
TIFF
A professional format used in photography, printing, and publishing. TIFF supports high bit depths, multiple layers, and various compression methods.
Strengths: Highest quality, industry standard for print, supports layers and metadata Weaknesses: Very large files, no browser support, overkill for web use Use when: Professional print workflows, archival storage
Which Format Should You Choose?
For web photographs: WebP with JPG fallback, or AVIF with WebP and JPG fallbacks For web graphics with transparency: WebP or PNG For icons and logos: SVG (with PNG fallback where needed) For print: TIFF or PNG at 300 PPI For email: JPG or PNG (WebP support in email clients is limited)
