GIF to BMP Converter

Summary

Upload a GIF and instantly download it as a BMP bitmap — animated GIFs export the first frame, fully in-browser with no file upload.

How it works

1. Select or drag a GIF image onto the upload area.
2. The browser decodes the GIF (capturing the first frame of animated GIFs) using its built-in image decoder.
3. The Canvas API reads all pixel data from the decoded frame using getImageData().
4. JavaScript assembles a valid 24-bit BMP file binary in memory, writing the file header, DIB header, and pixel rows in the correct bottom-up order.
5. A live preview of the converted image is displayed before download.
6. Click "Download BMP" to save the bitmap file to your device.

Use cases

• Convert a GIF logo or screenshot to BMP for use with legacy Windows software.
• Extract a static first frame from an animated GIF as an uncompressed bitmap.
• Prepare GIF images for workflows or tools that require BMP input.
• Convert GIF graphics to BMP for use in embedded systems or microcontroller projects.
• Process images privately without uploading to any third-party service.
• Convert GIF screenshots to BMP for compatibility with older paint programs.
• Archive GIF graphics in BMP format for lossless pixel-perfect storage.
• Supply BMP assets for game development or retro software projects.
