图像格式比较2026 年指南
不确定该使用哪种图像格式？并排比较不同格式——压缩类型、透明度、文件大小、浏览器支持等等。找到适合您项目的格式。
PNG vs JPG
Use PNG when you need transparency or pixel-perfect graphics. Use JPG for photographs and when smaller file size matters most.
WebP vs PNG
WebP delivers significantly smaller files than PNG with comparable quality. Use WebP for web delivery and PNG when you need universal compatibility or are working in design tools.
HEIC vs JPG
HEIC produces higher quality images at half the file size of JPG, but it lacks universal compatibility. Use HEIC within the Apple ecosystem and convert to JPG for sharing and web use.
SVG vs PNG
SVG is the clear winner for logos, icons, and scalable graphics. Use PNG when you need raster images, photographs, or complex visual content that cannot be represented as vectors.
GIF vs WebP
WebP is the superior choice for animated images on the web — smaller files, more colors, and better quality. Use GIF only when maximum compatibility is required.
AVIF vs WebP
AVIF offers better compression and color depth than WebP but at the cost of slower encoding and narrower compatibility. Use AVIF where cutting-edge performance matters; use WebP as the safe default.
TIFF vs PNG
TIFF is the professional choice for print and archival workflows. PNG is the practical choice for web, screen, and everyday use where lossless quality is needed.
BMP vs PNG
PNG is better than BMP in virtually every scenario. It offers lossless quality with dramatically smaller files, transparency support, and universal compatibility. BMP is a legacy format with no practical advantages for modern use.
选择合适的图像格式
选择合适的图像格式会对网站的性能、视觉质量和用户体验产生显著影响。每种格式都有其优势和不足——JPG 擅长压缩照片，PNG 能保持图像边缘清晰和透明度，WebP 兼顾了两者的优点，尤其适合网络传输，而像 AVIF 这样的新型格式则进一步提升了压缩效果。
最终的决定往往取决于您的具体使用场景：您是为了优化网页性能？为了保持设计素材的透明度？为了存档图像以备印刷？我们的并排比较分析了关键差异，以便您做出明智的选择。
