What is a WebP file?

WebP is a modern open image format developed by Google specifically for web performance. Saved under the .webp extension, it offers efficient lossy and lossless compression for web graphics.

Why convert WebP to BMP?

Certain industrial machinery, programmable logic controllers (PLCs), legacy Windows software, and digital signage players cannot decode WebP compression streams. Converting WebP to BMP rasterizes the image into an uncompressed byte array where every pixel color value can be read directly without any CPU decompression processing.

What is a BMP (Bitmap Image) file?

BMP, short for Bitmap Image File or Device-Independent Bitmap (DIB), is an uncompressed raster graphic format originally developed by Microsoft for early versions of the Windows operating system. Carrying the .bmp extension, it maps every pixel color value directly in an uncompressed byte array without utilizing lossy or lossless compression techniques.

How to open and view a BMP file?

Every version of Microsoft Windows natively opens BMP files using Microsoft Paint and Windows Photos. In addition, macOS Preview, Linux image viewers, web browsers, and image editing software support BMP files without extra plugins.

You can generate clean BMP files from your WebP graphics in milliseconds using our safe, offline browser conversion tool.
