How to Convert Multiple STEP Files to PPM?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting STEP files in under two minutes.
2. Load your STEP files
Add your STEP files to reaConverter. Whether it's a handful or an entire archive, the batch engine processes them efficiently.
Browse for files, drag them in, or add entire folders at once. reaConverter queues everything automatically.

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

4. Start STEP to PPM conversion
Start the conversion with one click. reaConverter handles everything and notifies you when it's done.

When the batch finishes, your PPM files are ready in the destination folder you chose earlier.
Before you convert STEP to PPM
STEP describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the PPM afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.
