How to Convert Multiple TIFF Images to IGES?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting TIFF files in under two minutes. Apply image edits like resize, crop, or color adjustment while converting.
2. Load your TIFF files
Add TIFF files to reaConverter. One file or a thousand, the process is the same. Everything runs locally on your machine.
You can drag-and-drop files, browse to a folder, or add entire directory trees including subfolders.

3. Select IGES as output format
Select IGES from the output format list and set your destination folder. You can also adjust quality and compression settings.

4. Start TIFF to IGES conversion
Click the Convert button to start. reaConverter will process all your files with the settings you selected.

When finished, your new .iges files will be waiting in the destination folder.
Before you convert TIFF to IGES
TIFF is made of pixels and IGES 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 IGES container, and that determines whether a CAD or design tool can work with it. One TIFF file can hold several pages or frames, while IGES 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.
