ERF or PNG: which should I use?

Use ERF for adjusting exposure and white balance with maximum latitude. Use PNG for screenshots, logos, text graphics and cut-outs. Keep in mind the main drawback of PNG: large files for photographs.

ERF is the RAW format of the Epson R-D1 rangefinder. It stores the unprocessed sensor data for maximum editing latitude, so most apps can’t show it as a normal picture.

Can I convert ERF to PNG without Photoshop or Lightroom?

Yes. The ERF file is opened on our servers, so you don’t need Photoshop or Lightroom or any other software installed. Upload the file, then download the finished PNG.

Is the ERF to PNG converter free?

Yes. Convert, preview and download a single result without creating an account. Premium adds batch conversion (many files into one ZIP) and larger uploads.
