Exporting compositions as Lottie

Render an After Effects composition out to Lottie and (optionally) upload it to your LottieFiles workspace, all from inside After Effects.

How to access this

Open the LottieFiles plugin in After Effects (Window > Extensions > LottieFiles).
Click Export in the top tab bar.

The Export tab opens to a list of every composition in your current After Effects project.

Before you start

Your After Effects project has at least one composition.
You're signed in to LottieFiles. The render itself works locally, but uploading to your workspace requires a sign-in.
For best results, read Preparing comps for Lottie before rendering — it covers the layer and comp choices that decide how cleanly the render comes out.

Steps

1. Find the composition you want to export

The Export tab shows every composition in your project. Use the search bar at the top to narrow the list — it filters by composition name as you type.

2. Select one or more compositions

Single render — click the Render icon next to the composition's name.
Batch render — tick the checkbox next to each composition you want, or use the Select all checkbox at the top. Hold Shift while clicking to select a range.

The number of selected compositions appears at the top of the list, and a global Render button at the bottom becomes available.

3. (Optional) Configure per-composition settings

Open per-composition export settings by clicking the gear icon on a composition row. You can change settings for one composition or open the global settings panel to change defaults for all compositions in the project.

Common settings include frame range, file naming, and target output format.

4. Run the render

Click Render to start. After Effects may prompt you to save the project before rendering — this is on by default but can be turned off (the plugin remembers your last choice).

If auto-save is on, the render starts immediately.
If auto-save is off, you'll see a Save project prompt. Save and the render begins.

The plugin navigates to the Render queue view (/compositions/render) and shows progress for each composition. Each composition renders in After Effects' background, so the AE UI stays responsive.

5. Save or upload the result

When a render finishes, the row shows the resulting Lottie file and an upload option.

Save locally — the rendered .lottie (or .json) file is written to your local export path.
Upload to workspace — select one or more finished renders and click upload. Pick a destination project or folder in your LottieFiles workspace. The plugin can also save the .aep source file alongside the Lottie if you tick Save AEP (storage limits apply — see Limits and plans).

Verifying the result

The render queue shows ✓ for each finished render.
Your local export folder contains the Lottie file(s).
If you uploaded, the file appears in your LottieFiles workspace at the destination you chose.
Opening the Lottie in a player (or in LottieFiles Creator) plays back what you'd expect.

If playback doesn't match your After Effects preview, check the Lottie compatibility matrix — it lists which AE features convert cleanly and which don't.

Troubleshooting

This section is the consolidated home for After Effects plugin troubleshooting. About 99% of the issues motion designers run into surface during render or export, so they all land here. The few non-export issues (plugin won't load, sign-in stuck) are linked to their specific chapters.

Render-side failures

Render queue stalls without progress — confirm After Effects isn't waiting on a modal (project save prompt, RAM warning). Bring the AE window forward; the plugin can't render while AE is blocked. If AE is responsive but the render still stalls, restart AE.
Render fails and the row shows an error icon — hover the row for the error message. The most common causes: missing fonts, missing footage, or an unsupported effect on a layer (see Lottie compatibility).
Output Lottie plays incorrectly (missing layers, broken transitions, wrong colors) — almost always a compatibility issue. Check the Lottie compatibility matrix for the specific feature you used.
Output Lottie is unexpectedly large — review the comp for raster layers, large pre-comps, or unnecessary effects. See Preparing comps for Lottie.
Upload fails with a network error mid-transfer — re-try the upload from the render queue. If it fails again, check that your workspace has enough storage (the upload UI shows the remaining quota).
"Save AEP" is disabled — your workspace storage is at or near its limit. Either free up space, upgrade, or untick Save AEP and upload just the Lottie.

Plugin doesn't appear under Window > Extensions — see Installation > Troubleshooting.
"Allow Scripts" checkbox is greyed out in AE preferences — quit and reopen After Effects. On Windows, opening AE once as Administrator typically resolves this.
Sign-in opens a browser tab but never returns — the plugin's sign-in flow hands off to your default browser. Confirm the browser actually loaded the LottieFiles login page; switch default browsers if it didn't. After signing in, return to After Effects and click Reload on the plugin panel.

Reporting issues

If you hit a problem not covered here, report it via the Help dropdown in the top-right of the plugin panel, or post in the LottieFiles community forum. Including your plugin version (from the About plugin modal) and After Effects version makes triage much faster.
