About ERF
ERF is the raw format of the Epson R-D1, the first digital rangefinder camera, made with Cosina in 2004 for Leica M mount lenses, and its R-D1s and R-D1x.
An ERF is built on TIFF and holds the 6 megapixel sensor's 12 bit data with the camera's settings and a preview.
No browser shows ERF by itself. Filepeek develops it with LibRaw, the open source raw decoder, using the camera's white balance, and Export saves a JPEG or a PNG.

Questions
How do I open an Epson R-D1 raw file?
Drop it on this page or press Peek an ERF. It opens right in your browser, with nothing to install.
Can I convert ERF to JPEG?
Yes. Choose Export, then Save as JPEG.
Why does it look flatter than the camera's JPEG?
The camera applied its own contrast and color. Filepeek develops the raw data neutrally, with the camera's white balance.
Is my photo uploaded?
No. The photo opens inside your browser and never leaves your device.
