The Free Lottie Hidden Layer Remover Online
Lottie files exported from design tools often carry hidden and fully transparent layers that never appear on screen but still add size. Our free hidden layer remover strips them out safely.
It keeps any layer that another layer uses as a parent, so removing invisible cruft never breaks a visible element. The animation renders exactly the same — just from a leaner file. Everything runs locally in your browser.
How to Remove Hidden Layers From a Lottie
Hunting for invisible layers in JSON is tedious. This tool finds and removes them for you:
Upload your Lottie JSON file
Drag and drop or click to browse. The tool counts how many layers can be removed.
Choose what to remove
Toggle removing hidden layers and removing fully transparent layers independently.
Preview — it looks identical
The live preview plays exactly the same, because only invisible layers are removed.
Download
Save the cleaned, smaller Lottie JSON.
No account, no server uploads — clean up in seconds.
Key Features
Safe Removal
Layers used as a parent are always kept, so cleaning up invisible layers never breaks a visible child.
Two Cleanup Rules
Remove layers marked hidden and layers with zero opacity — toggle each independently.
Smaller Files
Dropping unused hidden content shrinks the file and reduces parsing work — with no visual change.
Live Preview
Confirm the animation is untouched as you clean — the preview keeps playing identically.
Popular Use Cases
Optimize Before Shipping
Strip leftover hidden layers so production files are as lean as possible.
Clean After-Effects Exports
Remove guide, reference or off layers that got exported by mistake.
Faster Load & Parse
Fewer layers means less JSON to download and process on the client.
Tidy Design Handoff
Deliver clean files without invisible baggage to developers.
Batch Cleanup
Run it over a set of animations to standardize on lean, cruft-free files.
Pre-Minify Pass
Remove hidden layers first, then run the Minifier for the smallest possible output.
Pro Tips
Check the removed count
The info panel shows how many layers will be dropped, so you know the tool has something to do.
Parents are protected
A hidden layer that positions a visible one is kept automatically — you don’t need to worry about it.
Pair with the Minifier
Clean hidden layers here, then minify to squeeze the file size even further.
Verify in the preview
Watch the preview to confirm nothing you wanted disappeared before downloading.
Privacy and Security
We take your privacy seriously. Unlike most online converters that upload your files to remote servers, our tool processes everything locally.
No uploads – Your files are processed entirely in your browser. They never touch our servers.
No tracking – We don't log which files you convert or what settings you use.
No accounts – Use the tool immediately. No registration, no personal data required.
Inspect it yourself – Open DevTools and watch the network tab. You'll see zero file uploads.
Frequently Asked Questions
Everything you need to know about Lottie animations and our tools.
What does this remove?
Layers marked hidden (hd) and layers with a static opacity of 0 — the invisible cruft that adds size without appearing on screen.
Will it break my animation?
No. Layers that other layers use as a parent are always kept, so removing invisible layers never breaks a visible child’s position or transform.
Why remove invisible layers?
Hidden and transparent layers still add to file size and parsing work. Removing the ones that aren’t needed produces a leaner file that renders identically.
Can I choose what to remove?
Yes. Toggle removing hidden layers and removing transparent layers independently.
Does the animation look different afterward?
No. Only invisible layers are removed, so the visible result is identical — the live preview confirms it.
How much smaller will the file be?
It depends how much hidden content the file carries. Files exported with leftover guide or off layers can shrink noticeably.
Are my files uploaded to a server?
No. The entire process happens locally in your browser. Your file never leaves your device.
Is it free?
Completely free, with no registration, watermarks, or usage limits.
