How to Convert Multiple HEIF Images to GLTF?
1. Download and Install reaConverter
Download reaConverter and install it in seconds. The setup is straightforward — no complex configuration, no extra software required. Need edits? Resize, rotate, or add watermarks during conversion.
2. Load your HEIF files
Open reaConverter and add your HEIF files. You can load individual files, entire folders, or even nested subfolders.
Drop your HEIF files into the window or use File menu to browse and select folders.
3. Select GLTF as output format
Choose GLTF as the target format. Pick a destination folder or let reaConverter save files alongside the originals.
4. Start HEIF to GLTF conversion
Hit Convert and let reaConverter do the work. The progress window shows status for each file in real time.
After conversion, find your GLTF files in the output folder. Click 'Show converted files' to open it directly.
HEIF to GLTF: what carries over and what does not
HEIF is made of pixels and GLTF 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 GLTF container, and that determines whether a CAD or design tool can work with it. One HEIF file can hold several pages or frames, while GLTF 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.
