Zero Compression

BMP preserves raw pixel data without any compression — what you see in your WEBP source is exactly what you get in the output.

Legacy Compatibility

BMP is supported by every version of Windows ever released and countless legacy applications that may not recognize WEBP.

No Software Needed

Convert WEBP to BMP entirely in the cloud — no image editors or conversion utilities to install on your local machine.

About formats

WebP is an image format developed by Google, announced on September 30, 2010, designed to provide superior compression for web images in both lossy and lossless modes. The lossy mode is derived from the VP8 video codec's intra-frame coding (the same technology used in WebM video), applying block prediction, transform coding, and adaptive quantization to photographic content. The lossless mode uses a distinct algorithm combining predictive coding, color space transforms, backward reference to repeated pixel patterns, and entropy coding. WebP also supports alpha transparency in both modes — lossy WebP with transparency is unique among common web formats, offering semi-transparent images at much smaller sizes than PNG. The format supports animated sequences as well, providing a modern alternative to GIF with full-color support and dramatically better compression. One advantage is substantial file size reduction — lossy WebP produces images 25-35% smaller than JPEG at equivalent visual quality, and lossless WebP is typically 26% smaller than PNG, directly improving web page loading speed and reducing bandwidth costs. Universal browser support provides another key strength: Chrome, Firefox, Safari, Edge, and all mobile browsers now render WebP natively, achieving the broad adoption threshold needed for practical deployment. Google's core web infrastructure (Search, YouTube thumbnails, Gmail) uses WebP extensively, and the format is supported by major CDN platforms, CMS systems, and image processing services. WebP has established itself as the primary modern alternative to JPEG and PNG for web content.

BMP (Bitmap) is a raster image file format developed by Microsoft for the Windows operating system, introduced with Windows 3.0 in 1990. The format stores pixel data in a straightforward structure: a file header specifying dimensions, color depth, and compression method, followed by an optional color palette and then the raw pixel array. BMP supports color depths from 1-bit monochrome through 4-bit and 8-bit indexed color to 16-bit, 24-bit true color, and 32-bit with alpha channel. Most BMP files store pixels uncompressed (BI_RGB), though optional RLE compression is available for 4-bit and 8-bit modes. Pixels are arranged in bottom-up row order by default, with each row padded to a 4-byte boundary. One advantage is absolute simplicity — the format has no complex encoding, filtering, or compression layers, making BMP files trivial to read and write programmatically in any language. This simplicity also means BMP images render with zero decoding overhead, useful in scenarios where decompression latency matters. The format's deep Windows integration is another strength: BMP is the native bitmap format for Windows GDI, clipboard operations, and device-independent bitmap (DIB) handling, ensuring first-class support across the entire Windows ecosystem. While BMP's lack of compression produces large files unsuitable for web use or storage-constrained environments, it remains widely used as an intermediate format in image processing, as a clipboard exchange format, and in embedded systems where decoding simplicity outweighs file size.

Frequently Asked Questions

Why convert WEBP to BMP?

BMP is an uncompressed raster format with broad legacy support — some older Windows applications and embedded systems require BMP input specifically.

What programs open BMP files?

Windows Paint, Photos, Preview on macOS, GIMP, Photoshop, IrfanView, and virtually every image viewer supports BMP natively.

Will BMP files be larger than WEBP?

Yes — BMP stores pixel data without compression, so files are significantly larger. This is the trade-off for raw, uncompressed quality.

Is there any quality loss?

No — BMP preserves every pixel without compression artifacts. The conversion from WEBP to BMP is effectively lossless.

Does BMP support transparency?

Standard BMP does not support transparency. Transparent areas in your WEBP image will be filled with a solid background color.

Can I batch convert multiple files?

Upload several WEBP images simultaneously — each converts to BMP independently for individual download.
