Lottie File Size Optimizer & Compressor
To compress a Lottie file, drop your .json below and export it as optimized JSON or dotLottie. Lotiqlab minifies the JSON, packages it in the compressed dotLottie format, and can convert embedded PNG images to WebP for up to 80% smaller files.
How it works
- Drop your Lottie .json file below, or paste a URL to load it.
- The safe passes run automatically: editor metadata, unused assets, hidden layers, redundant keyframes and float noise all come out.
- Open Advanced options to push further, with a live before-and-after: WebP for embedded images, keyframe simplification.
- Export as optimized JSON, or as dotLottie for the smallest file.
By the numbers
- 0 KB
- Added overhead. Minification and dotLottie packaging change nothing about playback
Frequently asked questions
Quick answers about Lottie files and how Lotiqlab works.
How does Lotiqlab reduce Lottie file size?
It strips what only an editor reads (match names, property indices, default values), deletes unused assets and hidden layers, collapses keyframes that never change, and rounds the long float coordinates After Effects exports. On top of that, the dotLottie format zips the result into a compact archive, and embedded PNG images can be converted to WebP, which is typically the biggest win for image-heavy animations.
What is a dotLottie (.lottie) file?
dotLottie is a compressed container format for Lottie animations. It zips the JSON (and its assets) into a single small .lottie file that modern Lottie players support, often cutting file size dramatically versus raw JSON.
Will compressing change how the animation looks?
Not with the default settings. Every pass that runs by default is checked after it runs: the animation is sampled across its timeline before and after, and any pass that moves a value is thrown away rather than shipped. The settings that can change the output — image re-encoding and keyframe simplification — are off by default and live under Advanced options, where you can preview before exporting.
Why does Lottie file size matter?
Smaller animations mean faster page loads and better Core Web Vitals on the web, and smaller bundle sizes in iOS and Android apps. Image-heavy Lotties especially benefit from compression.
Do I need an account?
Not to optimize. Drop a file in, pick your settings, and download the smaller file — no account, no limit. A free account is only needed to open the file in the full editor, or to save it to the cloud.
