Smaller files, same fidelity. Full control over what gets optimized.

What’s new:

• Path simplification — Remove unnecessary anchor points within a tolerance threshold. Less path data, same motion.

• Keyframe simplification — Same bezier tolerance applied to keyframe interpolation. Cleaner easing data.

• Image compression — Toggle advanced compression (vips-wasm) and set output quality with a slider.

• Name truncation — Shorten property names in JSON to a set character length. No effect on rendering.

• Float rounding — Reduce decimal precision across the file. Small per-number, significant at scale.

• Property stripping — Granular toggles to exclude metadata, unused properties, blend mode defaults, 3D flags, and other data not needed for rendering.
