Convert Multiple 3D Files from a ZIP

Use a ZIP archive when several supported models need the same conversion pass. The worker scans supported entries and packages the resulting STL files together.

What to check before you export

ZIP processing has file-count, upload-size, decompressed-size, and output-size limits. Unsupported entries are skipped and duplicate output names receive a numeric suffix.

Frequently Asked Questions

Which files can a ZIP archive contain?

Supported model and image extensions are listed in the upload control. Unsupported files are ignored, while archives with no supported models return an error.

Will I get one download or many?

The conversion returns one ZIP containing the generated STL files. Review the output names before importing them into a slicer.

Can I repair every STL in a ZIP?

Batch conversion is supported. Repair currently focuses on one STL upload at a time so each topology result can be reviewed.
