Batch conversion

Batch conversion is for converting several files without repeating the same steps for each one.

When to use batch conversion

Use batch conversion when:

• You have many files that need the same output format.
• You are preparing assets for a web viewer, game engine, CAD handoff, or marketplace upload.
• You want one download after all conversions finish.

Convert multiple files

1. Open the converter.
2. Add all files that should use the same output format.
3. Include sidecar files such as .mtl, textures, or .bin files when the source format needs them.
4. Choose the output format.
5. Start conversion.
6. Download the converted files when the batch is done.

If the app bundles the results, the download is a zip file.

Keep batches simple

Batch conversion works best when every main file is going to the same output format. If some files need different targets, split them into separate batches.

Examples:

• Convert several .obj files to glb for a web catalog.
• Convert several CAD files to stl for 3D printing review.
• Convert several game assets to fbx for a downstream tool.

Sidecar files in a batch

Some files are not complete by themselves. For example, an .obj file may reference .mtl and image texture files.

When adding a batch:

• Keep each model's related files together.
• Add texture files at the same time as the main model when possible.
• Avoid renaming sidecar files before upload unless you also update the model references.

If a converted model has missing materials or textures, check the original source folder and convert again with the missing files included.

Practical limits

• Keep related sidecar files with the main file.
• Split very large batches into smaller groups.
• Retry failed files individually instead of restarting files that already converted.
• Check the first converted result before using the same settings for a large batch.
