Fast, instant WEBP to BMP conversion. No signup required. Just drop your .webp file and get .bmp in seconds.
Batch Settings
Transparency will be lost
WEBP supports transparency, but BMP does not. Transparent areas will be filled with a solid color (typically white). If you need transparency, consider converting to PNG or WebP instead.
Animation frames will be lost
WEBP supports animation, but BMP does not. Only the first frame (or a representative frame) will be preserved. If you need animation, consider converting to WebP or GIF instead.
Some metadata may not survive
Your WEBP file may contain EXIF, XMP, ICC metadata. BMP has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
在处理图片时，您是否曾遇到这样的情况：手头的WEBP文件，想在一些老旧软件、特定游戏引擎或打印店里使用，却发现它们不认这种格式？别担心，WEBP转BMP工具正是为您解决这类烦恼而生。WEBP虽然压缩效率高、网络传输快，但在兼容性方面有时确实会遇到“水土不服”。而BMP作为一种历史悠久、几乎所有图像处理软件都支持的位图格式，就像数字世界的“通用语言”，能确保您的图片在任何地方都能被准确无误地识别和显示。无论您是需要为项目准备素材，还是想把心爱的图片转换成最原始、无损的显示效果，我们的转换工具都能帮您轻松实现，让您的图片在不同平台间自由穿梭，畅行无阻。
- 微信表情包制作
- 游戏素材兼容
- 老旧系统图片适配
在大陆及台湾地区的一些老式或专用图像处理软件（如部分工业设计软件）中，对WEBP格式的支持度可能不如BMP，进行转换能有效避免兼容性问题。
About WEBP to BMP Conversion
WEBP or BMP — which format should you use? The answer depends on your needs. Here's a quick breakdown.
WebP is Google's modern image format offering both lossy and lossless compression at 25-35% smaller sizes than JPG/PNG. It has mostly universal platform support. BMP is an uncompressed raster format that preserves every pixel but produces very large files. It has universal platform support.
Full Name: WEBP uses WebP Image, while BMP uses Bitmap Image. Compression: WEBP uses Lossy & Lossless, while BMP uses None (uncompressed). Transparency: WEBP uses Yes, while BMP uses No.
So when should you convert WEBP to BMP? This conversion is ideal when you You need maximum device and software compatibility. This conversion helps you convert between formats quickly.

What Happens When You Convert WEBP to BMP
Your WEBP image is decoded into raw pixel data, then re-encoded as BMP.
Your WEBP file is decoded — the compressed/stored pixel data is expanded into raw RGBA (with alpha channel) pixels
Transparency is resolved: transparent pixels are composited onto a white background
Pixels are re-encoded using no compression (raw pixel storage)
Metadata (EXIF, ICC profiles) is transferred where BMP supports it
The BMP file is saved and ready for download

Common Mistakes When Converting WEBP to BMP
"My file's transparent background will carry over to BMP"
BMP doesn't support transparency. Transparent areas become solid (usually white). Save as PNG or WebP if you need transparency.
"BMP will be smaller than my WEBP file"
BMP uses no compression, so the output file is often larger than a lossy WEBP. If you need a small file, BMP may not be the right choice.
"My animated WEBP will stay animated after conversion"
BMP does not support animation. Only a single frame will be saved. Use WebP or GIF to preserve animation.
