What is a ERF file?
ERF is a proprietary RAW image format developed by Epson for its line of digital cameras, such as the Epson R-D1. It stores unprocessed sensor data, giving photographers full control over image adjustments like exposure, white balance, and contrast.
ERF files are based on the TIFF format and contain metadata specific to Epson’s camera system. While not widely used today, the format is valued by enthusiasts and collectors of Epson rangefinder-style cameras.
How to open ERF files
ERF files can be opened using Epson’s own software or RAW-capable editors such as Adobe Lightroom and Photoshop. Third-party tools like RawTherapee or IrfanView (with plugins) may also provide limited support for ERF files.
To enhance compatibility, you can convert ERF to JPG or PNG using AnyConv for easier access and sharing.

What is a PNG file?
PNG stands for Portable Network Graphics. It’s a popular raster image format developed as an open alternative to GIF. Released in 1996, PNG supports lossless compression, which means the image quality is preserved when the file is saved.
PNG is ideal for graphics that need transparency, sharp edges, or repeated editing - such as logos, icons, and screenshots. Unlike JPG, it retains full detail but usually results in larger file sizes.
How to open PNG files
PNG files are supported by nearly all operating systems and applications. You can open them using default image viewers on Windows, macOS, Linux, Android, and iOS.
Web browsers, design software like Adobe Photoshop, and online tools such as AnyConv also handle PNG files without issues.
