WEBP File

File extension	.WEBP
Category	Image File
Description	WebP is a new lossy image file format, whose mission is to overthrow JPEG, which has long been the ruler of the web image world. Although it is not expected to outdo JEG in image quality right away, it seems to be outdoing it in user-friendliness. With Webp, you get a same-quality image almost 50% smaller than its JPEG counterpart. Webp uses VP8 ñ an open-source codec, and a RIFF-based container, which creates a good potential for further development. The format was created by Google.

BMP File

File extension	.BMP, .RLE, .DIB
Category	Image File
Description	May be the simplest file format, BMP was developed jointly by Microsoft and IBM. That is why it is widespread on Windows platform. This extension is characterized a raster graphic format which is recognized by many programs today. In comparison with other bitmap formats, JPEG and GIF, BMP keeps color data for each pixel in the image and doesn't compress images to decrease a file size. That is what makes it perfect file format for printable images.

WebP to BMP Converter — Frequently Asked Questions ▼

Why would I need BMP instead of PNG or JPG?

BMP is required by legacy Windows applications, industrial software, game modding tools, and embedded systems that cannot read modern compressed formats. Windows GDI programs load BMP without any codec — it is the lowest-common-denominator Windows image format. PNG and JPEG require codec support that may not be present in older or embedded environments.

Is any quality lost when converting WebP to BMP?

For lossless WebP input: no. The pixel data is decoded and written to BMP exactly — pixel-identical output. For lossy WebP input: the WebP compression artifacts are already present in the decoded pixels. The BMP conversion itself adds no further quality loss — it preserves whatever the WebP contained.

Why is the BMP file so much larger than the WebP?

WebP uses efficient VP8/VP8L compression. BMP stores every pixel as uncompressed raw data — no compression of any kind. A 1920×1080 24-bit BMP is approximately 5.9 MB; the equivalent WebP might be 100–400 KB. BMP's large size is acceptable for use cases that need codec-free loading performance.

Does WebP transparency transfer to BMP?

24-bit BMP does not support alpha transparency — transparent areas are composited against white in the output. 32-bit BMP supports alpha, but many legacy applications only read 24-bit BMP. If you need transparency preserved and your application supports 32-bit BMP, specify 32-bit output in the converter settings.

What color depth does the BMP output use?

The default output is 24-bit RGB, which is the most compatible BMP variant supported by virtually all Windows applications. 32-bit RGBA BMP is available if your application supports it and you need alpha channel output.

Can I use the BMP output in a game modding tool?

Yes. Game asset editors and texture modification tools that require BMP input (common in older game modding communities) will accept the output BMP directly. Verify your specific tool's requirements for color depth (24-bit vs 32-bit) before converting.

Can I batch convert WebP folders to BMP?

The online converter handles multiple WebP uploads. For bulk conversion of WebP image libraries to BMP for legacy pipeline integration, Total Image Converter (Windows, $29.90) processes entire folders automatically.

Convert WEBP to BMP Online — Web Image to Uncompressed Bitmap

WebP is Google's compressed web image format, used by CDNs and modern browsers for fast delivery. BMP (Bitmap) is Microsoft's uncompressed raster format, used by legacy Windows applications, industrial software, game modding tools, and embedded systems that cannot read modern compressed formats. Converting WEBP to BMP decodes the WebP image and writes every pixel as uncompressed data in the BMP container — maximum compatibility with any application that reads BMP, with no decompression required at load time. No software installation required.

What Is a BMP File?

BMP (Bitmap Image File) is Microsoft's native raster image format, introduced with Windows 1.0 in 1985. It stores pixel data as an uncompressed grid of color values — no lossy or lossless compression by default — making it the simplest and most universally readable Windows image format.

Uncompressed: Pixels are stored as raw RGB or RGBA values — no compression artifacts, no decoding overhead.
Color depth: Supports 1, 4, 8, 16, 24, and 32 bits per pixel — most common output is 24-bit RGB.
Windows native: Natively supported by all Windows APIs, GDI applications, and Win32/Win64 software without additional codecs.
No metadata: BMP stores only pixel data and basic image dimensions — no EXIF, ICC color profiles, or embedded thumbnails.
Compatibility: Supported by all Windows applications, many Linux/macOS image tools, and virtually all legacy imaging software; not efficient for web delivery.

Who Needs WEBP to BMP Conversion?

Legacy Windows applications: Industrial control software, medical imaging viewers, and legacy Windows desktop apps that accept BMP natively but cannot read WebP.
Game modding tools: Game asset editors and texture modification tools that use BMP as their native import format for textures and sprites.
Embedded system firmware: Microcontroller and embedded display firmware that reads raw BMP pixel data directly without a software decoder.
Automated Windows pipelines: Windows batch processing scripts using GDI or Win32 APIs that require uncompressed BMP input to avoid codec dependencies.
Print and scanning software: Older scanner and print drivers that output or accept BMP as the baseline format for scan and print jobs.
Archive compatibility: Converting WebP assets to BMP for long-term archival in systems where BMP is the lowest-common-denominator readable format.

WEBP vs BMP — Key Differences

Property	WEBP	BMP
Introduced	2010 (Google)	1985 (Microsoft)
Compression	VP8/VP8L (lossy or lossless)	Uncompressed (raw pixel data)
File size	Small (optimized for web delivery)	Large — 3× or more vs PNG/WEBP
Compatibility	Modern browsers only; poor legacy support	All Windows software; universal legacy support
Transparency	Full alpha channel	Supported in 32-bit BMP; not in 24-bit
Best for	Web image delivery	Legacy Windows apps, embedded systems, game tools

How WEBP to BMP Conversion Works

The converter decodes the WebP image using the VP8 (lossy) or VP8L (lossless) algorithm to recover the full-resolution RGBA pixel grid. The decoded pixel data is then written into the BMP container format: a BMP file header records image dimensions, bit depth (typically 24-bit RGB), and pixel data offset; the pixel rows are written in bottom-up order (BMP's default row order), with each row padded to a 4-byte boundary. For 24-bit BMP output, any WebP alpha transparency is composited against a white background. For 32-bit BMP output, the alpha channel is preserved as the fourth byte per pixel. The resulting BMP file is uncompressed and immediately readable by any Windows application without codec installation.

WEBP to BMP Use Cases

Legacy app asset import: A developer converts WebP marketing graphics to BMP for import into a legacy Windows desktop application that uses BMP for UI asset loading.
Game texture modding: A game modder converts WebP textures downloaded from a mod site to BMP for import into a game texture editor that requires BMP format.
Embedded display firmware: An engineer converts WebP product images to BMP for loading into an industrial display controller that reads raw BMP pixel data from flash storage.
Print driver input: Converting WebP artwork to BMP for submission to an older print driver that accepts BMP for precise raster output.
Batch conversion: Total Image Converter (Windows, $29.90) converts entire WebP image folders to BMP in one automated run for bulk legacy pipeline processing.
GDI batch processing: Converting WebP assets to BMP for a Windows GDI batch processing pipeline that manipulates pixel data directly without codec overhead.
