Compression Techniques We Apply
Remove Unused Properties
~5-15%Strip metadata, editor-specific keys (ddd, nm, mn), and properties that don't affect rendering.
Simplify Path Data
~10-30%Reduce decimal precision on bezier curves and vertices from 6+ to 2-3 decimal places.
Collapse Static Transforms
~5-20%Replace animated transform arrays with static values when only one keyframe exists.
Remove Hidden Layers
~VariableDelete layers with opacity 0 or visibility disabled that never appear on screen.
Minify JSON Output
~15-25%Remove whitespace, newlines, and indentation from the final JSON for minimal transfer size.
Deduplicate Assets
~5-15%Identify and merge duplicate shape groups, gradient definitions, and image references.

Manual Optimization Guide
1. Audit Your Composition in After Effects
- Delete unused layers and pre-comps before exporting.
- Flatten unnecessary layer hierarchies.
- Replace raster images with vector shapes where possible.
- Avoid expressions that generate complex keyframe data.
2. Optimize Shape Complexity
- Use fewer anchor points on paths — simplify in Illustrator before importing.
- Avoid heavily nested groups and compound paths.
- Convert strokes to fills when stroke animation isn't needed.
- Use shape repeaters instead of duplicated layers.
3. Export with Bodymovin Best Practices
- Enable 'Standalone' mode to avoid external dependencies.
- Disable 'Include hidden layers' in export settings.
- Set 'Extra compositions' to only what's needed.
- Use standard features — avoid unsupported effects.
4. Post-Export Optimization
- Run JSON through a minifier (e.g., jq -c or online tools).
- Use LottieFiles optimizer or our compressor tool above.
- Validate playback after compression to catch visual regressions.
- Serve with gzip/brotli compression on your CDN.
