Convert BMP Images to WebP
If PNG is about “don’t lose detail,” WebP is about “make it web-friendly.”
This tool converts BMP → WebP so old bitmap files stop being huge and start behaving like modern website assets.
Why Convert BMP to WebP?
BMP is often unnecessarily large.
WebP is built to reduce size while keeping images looking good — which helps when you’re:
- publishing images on a site
- sending files to clients
- trying to keep folders lightweight
- optimizing page load time (smaller images download faster)
If your BMPs are photos, WebP is usually a strong default.
Where WebP Shines on Websites
WebP is most useful when the image is part of a page load:
- hero images and banners
- blog covers
- product photos
- portfolio galleries
- background images (where big files quietly hurt performance)
Smaller files mean less bandwidth and faster delivery — especially on mobile.
Common Use Cases
-
Web publishing Turn heavy BMPs into WebP so pages load faster.
-
Exports from older tools Convert BMP files from legacy software into a modern format.
-
Asset cleanup Standardize old folders so everything is easy to preview, upload, and reuse.
-
Batch conversion Convert a whole set and download everything as a single ZIP.
How to Use the Converter
-
Add BMP images Drag & drop or select one or multiple
.bmpfiles. -
Convert to WebP This variant locks the output to WebP for a fast, focused workflow.
-
Download results Save images one-by-one or download all converted files as a ZIP.
No setup, no uploads, no extra steps.
Important Notes
- Size reduction depends on the image. Photos usually shrink a lot; flat graphics vary.
- Some BMP files may not decode in every browser. Support depends on the BMP type and your browser engine.
- Transparency isn’t invented. If the original image doesn’t contain transparency, the WebP output won’t magically gain it.
- Metadata is removed. EXIF and similar metadata is typically stripped during conversion.
How This Tool Works
All processing happens entirely in your browser:
- BMP images are decoded using modern browser graphics APIs.
- Conversion runs inside Web Workers to keep the interface responsive.
- Multiple files are processed in parallel for faster batch results.
- Finished WebP images are bundled locally into a ZIP for download.
