About This Tool

This is the ultimate 3D model compression tool powered by glTF-Transform. It combines mesh simplification (reducing polygon count), texture optimization (resize, format conversion to WebP/JPEG), and Draco encoding (geometry compression) into one streamlined workflow. Everything runs locally in your browser - no uploads, no servers.

Frequently Asked Questions

Q

What does this tool do differently from the vertex/texture-only tools?

A

This tool applies ALL optimizations in a single pass: mesh simplification + texture resize/compression + Draco encoding. It is the most comprehensive option for maximum file size reduction.

Q

What is the difference between mesh simplification and Draco encoding?

A

Mesh simplification actually reduces the number of faces/vertices in your model — lower ratio means fewer polygons, smaller files, but visible quality loss. Draco encoding compresses the existing geometry data without changing face count, achieving 50-90% size reduction with nearly no visual difference. For best results, use both together: simplify first, then apply Draco.

Q

How much smaller will my model be?

A

Results vary widely: simple models may see 30-50% reduction, while complex textured models can achieve 70-90% reduction when all options are enabled.

Q

Should I enable all compression options?

A

For web deployment, enabling all options (simplify + texture compress + Draco) gives the smallest files. For archival purposes, you may want to skip simplification to preserve full detail.

Q

Which texture format is best for web?

A

WebP offers the best compression ratio (~30% smaller than JPEG at similar quality) and is supported by all modern browsers. Use JPEG for maximum compatibility if needed.
