Is my image uploaded to any server?

No. The conversion happens entirely in your browser using the Canvas API. Your image never leaves your device.

What BMP format is produced?

The tool outputs an uncompressed 24-bit BMP (DIB header, BGR pixel order), which is the most widely compatible BMP variant.

Does the tool support animated WebP?

Only the first frame is converted, since Canvas renders one frame at a time. Animated WebP sequences are not supported.

Are there file size limits?

There is no enforced limit, but very large images (above 20 MP) may be slow due to the amount of pixel data that must be processed in JavaScript.

Can I convert multiple files at once?

Yes. Select multiple WebP files at once using the file picker and each will be converted and queued for download individually.

Summary

This tool converts WebP images to the BMP (Bitmap) format using the HTML5 Canvas API, entirely inside your browser. No file is ever sent to a server, so your images stay private. The output is an uncompressed 24-bit BMP file compatible with Windows, legacy software, and tools that do not support WebP.

How it works

Select or drag a WebP image file onto the drop zone.
The tool decodes the WebP using an HTML Image element and draws it onto a Canvas.
The Canvas pixel data is read and packed into a valid 24-bit BMP binary blob.
A download link is generated so you can save the BMP file immediately.
All processing happens in your browser — no data leaves your device.

Use cases

Prepare images for Windows applications that require BMP format.
Convert WebP screenshots to BMP for legacy design or print workflows.
Create BMP assets for embedded systems or older software tools.
Batch-inspect WebP images and export each as BMP without installing software.
Verify pixel-accurate rendering of WebP images in BMP format.
