ERF to BMP3
File Converter

ERF (Epson Raw File), is a raw image file format used by Epson digital cameras, capturing all the data directly from the camera’s sensor without any in-camera processing or compression. This format enables photographers to have extensive control over post-processing, allowing for adjustments to exposure, color balance, and other parameters to achieve the desired image quality. However, ERF files are typically larger in size compared to standard compressed image formats and require specialized software for viewing and editing.

BMP3 (Bitmap Image File V3) is an image file format developed by Microsoft, commonly used for storing two-dimensional digital images in a wide range of color depths. While BMP files are capable of storing detailed images without any compression—preserving the original quality—they often result in large file sizes, making them less ideal for web usage or sharing.
