AEtoGSAP is an After Effects extension that exports animations into web-friendly formats such as GSAP. It analyzes selected layers and generates GSAP-ready code, preserving timing, duration, and custom easing from After Effects, where easing is carried over as custom eases.
The extension supports Shape Layers, Text Layers, Nulls, and parenting. Shape work covers ellipse and rectangle size, corner radius, Polystar point count and radius, fill and stroke color, stroke width, dashed lines, and custom paths. Text layers export with font data, alignment, color, and basic transforms, and basic solid layer transforms are handled too. Effects, layer styles, expressions, trim paths, and text animators are not supported.
Alongside the GSAP timeline, AEtoGSAP outputs HTML and CSS files so you can run the export and preview it instantly without additional setup. The GSAP, HTML, and CSS can also be exported separately. A demo version is available to confirm compatibility.
