How to Convert Multiple ERF Images to STEP?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting ERF files in under two minutes. Built-in editing tools let you resize, crop, or watermark as you convert.
2. Load your ERF files
Open reaConverter and import your .erf files. No file limits, no slowdowns. Add as many as you need.
Drag-and-drop ERFs directly into reaConverter or use the folder browser to load entire directories.

3. Select STEP as output format
Pick STEP as the output format. Set the destination folder and optionally configure resolution, quality, or file naming.

4. Start ERF to STEP conversion
Press Convert to begin processing. You can watch the progress or minimize and let it run in the background.

Your converted STEP files will appear in the destination folder as soon as processing completes.
