How to convert HEIC to BMP

1. Upload your HEIC file

   Click the upload area or drag a HEIC image. The file is processed locally.

2. Convert

   Press Convert. Sharp decodes the HEIC and re-encodes it as an uncompressed 24-bit BMP. No quality setting is needed — BMP stores raw pixel data.

3. Download the BMP

   Click Download to save the .bmp file. BMP files are large because every pixel is stored uncompressed — expect a significantly bigger file than the source.

4. When to use BMP

   BMP is useful for legacy Windows applications, older image-processing pipelines, or tools that cannot read compressed formats. For any modern use case, PNG provides the same lossless quality at a fraction of the file size.
