WebP

WebP Web Picture format

WebP is Google's web image format. It supports both lossy and lossless compression plus alpha transparency, and typically produces files 25 to 35 percent smaller than JPG at similar visual quality. Every current browser displays it.

BMP

BMP Windows Bitmap

BMP is the uncompressed bitmap format native to Windows. Files are large because each pixel is stored raw, but almost every program, embedded device and legacy system can read it.

How to use the WebP to BMP Converter

  1. 1

    Click Choose files or drop your WebP images onto the page.

    Click Convert, then download each BMP or all of them as a ZIP.

Why convert WebP to BMP?

WebP files mostly arrive when you save an image from a website, because Chrome and most large sites now serve WebP instead of JPG or PNG. Older desktop software, some print shops and many upload forms still reject it. Choose BMP only when a legacy program or device needs uncompressed bitmaps.

WebP to BMP settings

Pick a background colour to replace transparent areas. Animated WebP files are converted using their first frame. You can also cap the width and height, which resizes large photos in the same step.

Frequently asked questions

Will the BMP lose quality?

BMP is lossless, so the conversion keeps every pixel or sample that is in your WebP file. It cannot bring back detail that WebP compression already removed, and the BMP file will usually be larger.

Is transparency kept when converting WebP to BMP?

BMP cannot store transparency, so transparent areas are filled with a solid colour. White is used by default; you can pick any background colour in the options before converting.

Will the BMP be smaller than the WebP?

No, usually larger for photos: as a rough guide, the BMP comes out at around 34× the size of the WebP, depending on the quality setting.
