How to Convert Multiple AVIF Images to STEP?
1. Download and Install reaConverter
First, grab reaConverter from the download button below. Installation is fast, and the software runs offline — no account or signup needed. reaConverter also includes editing tools: resize, crop, rotate, and more.
2. Load your AVIF files
Open reaConverter and add your AVIF files. You can load individual files, entire folders, or even nested subfolders.
Drop your AVIF files into the window or use File menu to browse and select folders.

3. Select STEP as output format
Choose STEP as the target format. Pick a destination folder or let reaConverter save files alongside the originals.

4. Start AVIF to STEP conversion
Hit Convert and let reaConverter do the work. The progress window shows status for each file in real time.

After conversion, find your STEP files in the output folder. Click 'Show converted files' to open it directly.
How AVIF and STEP differ in practice
AVIF is made of pixels and STEP is a geometry format, so the two describe images in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains editable geometry or a picture placed inside a STEP container, and that determines whether a CAD or design tool can work with it. One AVIF file can hold several pages or frames, while STEP holds one image each. reaConverter writes a separate output file per page and numbers them, so a single input can produce a whole folder of results.
