Why we like it

Loop Tools Pro earns a look for keeping animation non-destructive: loops run on markers and expressions rather than baked keyframes, so a full reset is one button away.

What is Loop Tools Pro?

Loop Tools Pro is a script for After Effects that applies multiple non-destructive loop cycles to a single layer while guaranteeing a seamless stop. Your original keyframes stay untouched, because the loops run on a marker-driven "Super-Expression" tied to LOOP_START and LOOP_END markers rather than rewriting your animation.

You can create and manage several unique loop cycles on the same layer property, and multi-layer support lets you apply loops, rebake keyframes, or delete expressions across dozens of selected layers at once. Ranges can be auto-detected from your selected keyframes or dialed in manually with UI sliders. A Smart Rebake function corrects transitions to help ensure a seamless loop exit, and it works with Position, Scale, Rotation, Opacity, Path, and more.

A "Delete Loops" button removes all script-generated markers and expressions when you need to reset, and the controls live in a dockable UI panel. The code uses matchNames for compatibility with all language versions of After Effects, and it supports releases from CS6 through 2026.

Who is Loop Tools Pro best for?

Loop Tools Pro is best for after Effects animators who need to apply and manage repeating loop cycles on layer properties without altering their original keyframes.

How much does Loop Tools Pro cost?

Loop Tools Pro is completely free to download and use.

Frequently asked questions

Does Loop Tools Pro work with After Effects 2026?

Loop Tools Pro supports a wide range of After Effects versions, from the 2026 release back through 2025, 2024, 2023, 2022, 2021, 2020, and the older CC 2019 through CC 2014, CC, and CS6. Its code uses matchNames rather than property names, so it runs across all language versions of After Effects on CS6 and up. If you are working on any of those builds, it should load and run.

Can Loop Tools Pro loop multiple layers at once?

Loop Tools Pro includes multi-layer support, so you can apply loops, rebake keyframes, or delete expressions across dozens of selected layers at once. On a single layer it also handles multiple unique loop cycles on the same property. Ranges can be auto-detected from your selected keyframes or set manually with the UI sliders, giving you control over where each cycle starts and ends before it is applied.

Which properties can Loop Tools Pro loop in After Effects?

Loop Tools Pro works with common transform and animation properties in After Effects, including Position, Scale, Rotation, Opacity, and Path, among others. It keeps your original keyframes untouched by applying a marker-driven "Super-Expression" tied to LOOP_START and LOOP_END markers, so the looping stays non-destructive. A Smart Rebake function is included to correct transitions and help ensure a seamless loop exit when a cycle ends.

How do I remove loops created by Loop Tools Pro?

Loop Tools Pro adds a "Delete Loops" button that automatically removes all script-generated markers and expressions, letting you reset a layer if you need to start over. Because the workflow is non-destructive, your original keyframes remain in place after cleanup. The tool lives in a dockable UI panel, so the controls for applying, rebaking, and deleting loops stay available while you work in your composition.

Is Loop Tools Pro free, and how is it licensed?

Loop Tools Pro is listed as free in this catalog. It ships with the aescripts + aeplugins v4 licensing framework, which uses a trial and full structure, so check the developer's page for the current licensing terms and any trial details. The release notes mark it as an initial commercial release from November 2025, so licensing specifics may change over time on the developer's page.
