When to Convert
Common scenarios where this conversion is useful
Legacy software compatibility
Older image editors, CAD programs, and Windows applications that don't support WebP can open BMP files natively without plugins.
Uncompressed editing source
BMP provides a lossless, uncompressed representation of your image. Use it as a source for editing workflows where you need zero compression artifacts.
Embedded systems and firmware
Many embedded displays, firmware splash screens, and industrial equipment require BMP format for bitmap rendering.

Frequently Asked Questions
The conversion itself is lossless — every pixel in the decoded WebP is preserved exactly in the BMP output. However, if your original WebP used lossy compression, those artifacts will be present in the BMP.
BMP stores image data uncompressed (or with minimal RLE compression). A 500 KB WebP image can easily become 5-15 MB as a BMP. This is normal and expected.
Standard BMP does not support transparency. If your WebP has an alpha channel, the transparent areas will be rendered as white in the BMP output.
No. The conversion happens entirely in your browser using the Canvas API. Your file never leaves your device.
There is no hard limit, but very large images (over 50 megapixels) may be slow or cause memory issues depending on your device.
BMP does not support animation. If you convert an animated WebP, only the first frame will be captured in the BMP output.
The converter produces 24-bit BMP files (16.7 million colors), which is compatible with virtually all software that reads BMP.
Yes. The converter works in any modern mobile browser on iOS and Android. Just tap the drop zone to select your file.
BMP is needed for specific legacy software, embedded systems, or workflows that require raw uncompressed bitmap data. For most purposes, PNG is a better lossless choice.
Yes. You can drop multiple files at once and they will all be converted individually.
