What is Transparent Image Generator?

An AI-powered design tool that instantly generates high-quality, transparent assets for creators, businesses, and digital artists.

Are my files uploaded anywhere?

No. Your BMP is decoded and re-encoded inside your browser, so the file never leaves your device. That also makes it fast, even on large images.

Why convert BMP to WebP?

WebP is a good choice for fast-loading website images that may need transparency. BMP is usually used for legacy Windows software.

Which browsers can create WebP files?

Chrome, Edge and Firefox create WebP directly. Older Safari versions can show WebP but cannot create it; if the converter reports this, open the page in Chrome, Edge or Firefox.

How do I convert BMP to WebP?

Drop your BMP file into the converter above. It is decoded in your browser, redrawn at full resolution and saved as WebP. BMP has no transparency, so the WebP will be fully opaque. To cut out the background, use the background remover. Nothing is uploaded and there is no watermark.

Details

About BMP

BMP is an old, mostly uncompressed Windows bitmap format. Files are very large for what they contain, and many websites and apps no longer accept them.

About WebP

WebP is a modern web format from Google. It supports lossy and lossless compression, alpha transparency and animation, and is usually smaller than the same image as JPG or PNG. Every modern browser shows it, but some older desktop apps and upload forms still reject it.

Frequently asked questions

Yes. It is free with no signup, no watermark and no daily limit, because the conversion runs on your own device instead of a paid server.
