How do I convert ERF to JPG?

Upload your ERF file above. It is converted to JPG automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting ERF to JPG lose quality?

JPG is lossy, so some fine detail is discarded to make the file smaller. Raise the quality in Settings for a closer copy.

ERF or JPG: which should I use?

Use ERF for adjusting exposure and white balance with maximum latitude. Use JPG for photos you share, email, print or upload. Keep in mind the main drawback of JPG: no transparency, and every re-save loses a little more detail.

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 JPG 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 JPG.

Is the ERF to JPG 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.
