Convert WebP to BMP
Turn WebP images into BMP bitmaps for older software. Everything happens in your browser, so your images never leave your device.
Why convert WebP to BMP?
WebP is great for websites, but plenty of apps, upload forms and print services still won't take it. BMP is simple and uncompressed, and some older or specialised software won't take anything else.
Transparent areas get a background
BMP has no transparency, so any transparent parts of your WebP are filled with a solid colour. White is the default, and you can pick another colour before converting, for example to match the page or slide the image will sit on. If you need to keep the transparency, convert to PNG instead.
Animated WebP files
If your WebP is animated, only the first frame is converted and you get a still BMP. Non-animated WebP files convert as normal.
File size and quality
BMP is uncompressed, so nothing more is lost in the conversion. It can't bring back detail the WebP compression already removed, though. BMP is usually stored uncompressed, so the file will be many times larger: about 36 MB for a 12-megapixel photo.

Questions
What happens to transparent areas when I convert WebP to BMP?
BMP can't store transparency, so transparent areas are filled with a background colour. It's white by default, and you can choose any colour before converting.
Can I convert an animated WebP?
Yes, but only the first frame is kept, so you get a still BMP.
Will converting WebP to BMP reduce quality?
No further loss: BMP stores the decoded pixels exactly. It can't restore detail the WebP compression already removed, and the file will be bigger.
Are my WebP images uploaded anywhere?
No. The conversion runs in your browser, on your own device, so your images are never sent to a server. Once the page and converter have loaded, it keeps working even if your connection drops.
