Why convert BMP to WebP?
BMP and WebP serve different purposes. Converting between them lets you use whichever format works best for your situation.
What is a BMP file?
Bitmap Image File: BMP is an uncompressed image format from Microsoft. Files are large because every pixel is stored individually without compression. It is mostly used in legacy Windows applications.
Created by: Microsoft, introduced with Windows 1.0 in 1985
Used for: Legacy Windows applications, raw pixel data, internal processing
Technical details: Typically uncompressed, storing raw pixel data. Supports various color depths. Files are significantly larger than equivalent PNG or JPEG.
Compatibility: Natively supported on Windows. Most image editors can read BMP, but web browsers have limited support.
What is a WebP file?
Web Picture format: WebP is Google's image format built specifically for the web. It produces smaller files than both JPEG and PNG while keeping similar quality. Most modern browsers support it, though older software sometimes does not.
Created by: Google, first released in 2010
Used for: Web images, page speed optimization, anywhere file size matters
Technical details: Supports both lossy and lossless compression, plus transparency and animation. Typically 25-35% smaller than JPEG at comparable quality.
Compatibility: All modern browsers (Chrome, Firefox, Safari, Edge). Some older image editors may not open WebP files.
