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.

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

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.

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

Drop a WebP image and download it as a 24-bit BMP file — entirely in your browser, nothing uploaded.

Done!

Drop a WebP image and download it as a 24-bit BMP file — entirely in your browser, nothing uploaded.

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.
