将 WEBP 转换为 BMP

BMP是某些应用程序和嵌入式系统专门因其简单性而需要的旧版Windows格式。相比之下，WebP是一种具有复杂压缩的现代网络格式。将WebP转换为BMP会生成旧版软件无需任何编解码器即可加载的未压缩像素数据。

何时将 WEBP 转换为 BMP

🏭
工业自动化

PLC显示器和嵌入式HMI系统通常只接受BMP用于屏幕图形。

🖥️
旧版Windows应用

Windows XP时代及更早的软件依赖BMP作为其原生图像格式。

⚙️
无需解码器

读取BMP文件非常简单——像素数据从定义的偏移量开始。非常适合受限系统。

🔧
管道测试

BMP的简单性使其在格式复杂性不受欢迎的图像处理管道测试中非常有用。

WEBP vs BMP — 格式对比

属性 WEBP (input) BMP (output)
Format type Raster Raster
Compression Lossy+Lossless None
Transparency Yes (alpha) No
Best used for Web images, modern apps Legacy Windows apps
File size Very Small Very Large
ℹ️ Important note

只有动画WebP的第一帧被转换为BMP。透明度被白色背景替换，因为BMP不支持Alpha通道。

WEBP
  • 文件扩展名.webp
  • 描述WebP provides superior lossless and lossy compression for images on the web. WebP images are typically 25-34% smaller than comparable JPEG or PNG files.
  • 相关程序Google Chrome, Firefox, Adobe Photoshop (with plugin), GIMP
  • 开发者Google
  • MIME 类型image/webp
BMP
  • 文件扩展名.bmp
  • 描述BMP (Bitmap) stores uncompressed bitmap digital images independently of the display device. Large file sizes but no quality loss.
  • 相关程序Microsoft Paint, Adobe Photoshop, GIMP, MS Photo Editor
  • 开发者Microsoft
  • MIME 类型image/bmp

WEBP vs BMP：完整格式指南

功能
WEBP
BMP
压缩
WEBPLossy+Lossless
BMPNone
透明度
WEBPFull 8-bit alpha channel — same capability as PNG, with better compression efficiency
BMPOnly in 32-bit BMP via BITMAPV4/V5HEADER alpha channel — inconsistently supported by applications
动画
WEBPSupported — animated WebP stores multiple frames with per-frame timing data, offering vastly better quality and smaller files than animated GIF
BMPNot supported
色彩深度
WEBP24-bit RGB + 8-bit alpha — 16.7 million colors with full alpha transparency
BMP1-bit monochrome to 32-bit RGBA — most common use is 24-bit (16.7 million colors)
文件大小
WEBP25–35% smaller than an equivalent-quality JPEG or PNG — typically 30–80 KB for standard web images
BMP3 MB – 25 MB per image — a 1920×1080 24-bit BMP is approximately 5.9 MB
浏览器支持
WEBPChrome 23+, Firefox 65+, Edge 18+, Safari 14+, Opera 12+. Not supported in Internet Explorer or Safari prior to iOS/macOS in 2020.
BMPTechnically supported by most browsers but virtually never used on the web due to enormous file sizes
最适合

BMPLegacy Windows apps

常见使用场景：WEBP → BMP

⚙️ Legacy Windows applications🔧 Hardware display systems
⚠️WebP to BMP dramatically increases file size while eliminating all web optimization. This conversion is only useful for specific legacy system compatibility requirements.
WEBP

关于 {from} 格式 WEBP

Google developed WebP and announced it in 2010 using technology from the VP8 video codec. Initial adoption was Chrome-only, but Firefox added support in 2019 and Apple's Safari 14 followed in 2020 — finally making WebP viable for all modern web deployments without compatibility caveats. It is now Google's officially recommended image format for web performance optimization.

优点
+25–34% smaller than JPEG/PNG at equal quality — direct page load improvement
+Both lossy and lossless compression modes in a single format
+Full alpha transparency like PNG at significantly smaller file sizes
+Animated WebP replaces GIF with full-color quality and dramatically smaller files
局限性
−Not supported in Internet Explorer or Safari before iOS 14 / macOS Big Sur
−Print shops, Outlook, and Office apps don't accept WebP
−Limited native support in professional desktop imaging software
−Not practical for offline print workflows requiring Photoshop or Lightroom native support
使用时机
→Websites targeting modern browsers (Chrome, Firefox, Edge, Safari 14+)
→E-commerce and high-traffic sites where image performance impacts conversions
→Mobile-first apps where bandwidth and load time are critical
→Replacing animated GIFs with higher-quality, much smaller animated alternatives
提示
•Use the HTML <picture> element to serve WebP with a JPG fallback for older browsers
•WebP lossy quality 80 is perceptually equivalent to JPEG quality 90
•Animated WebP is dramatically better than GIF — smaller, full-color, and smoother
•CDNs like Cloudflare and Cloudinary auto-convert and serve WebP to supported browsers
BMP

关于 {from} 格式 BMP

BMP (Device-Independent Bitmap) was introduced by Microsoft with the Windows 3.0 SDK in 1990 as the native raster format for Windows. It stores pixel data with zero compression, ensuring perfect reproduction across all hardware. BMP dominated early Windows computing for wallpapers, icons, and application graphics. As the internet grew, its massive file sizes made it impractical for any networked use, displacing it with JPG, PNG, and WebP.

优点
+Zero compression artifacts — the highest possible fidelity for raw storage
+Simple, well-documented format trivial to read/write programmatically
+Universal support across all Windows software and development tools
+Direct pixel data access with no decoding overhead
局限性
−Extremely large files — a 1080p image is ~6 MB vs ~300 KB as JPG
−No practical web use — impractically large for any internet delivery
−Limited support outside Windows ecosystem
−No meaningful advantages over PNG for any modern use case
使用时机
→Legacy Windows applications that exclusively require BMP format
→Automated Windows image processing pipelines as an intermediate format
→System resource files (wallpaper, specific application bitmaps)
→When absolute raw pixel fidelity is needed and file size is irrelevant
提示
•PNG achieves identical lossless quality to BMP at 50–70% smaller file sizes
•Convert to JPG for a 95%+ file size reduction with visually excellent quality
•24-bit BMP and 24-bit PNG are visually identical — PNG is always the better choice
•There are essentially no modern use cases where BMP is preferable to PNG
