Every page on WebReady Lotties — the free, private tool to preview Lottie files in your browser and diagnose why an animation breaks on real websites.
Drop a .json or .lottie file to preview it on transparent, white, black or custom backgrounds, switch SVG / Canvas renderers, and get a plain-English diagnosis.
This page — a human-readable index of the site.
Machine-readable sitemap for search engines.
True browser preview with the real lottie-web engine, including play/pause, frame scrubbing, speed and loop.
Spot JPEGs that can't be transparent, PNGs with no alpha channel, and blend modes lottie-web can't render.
Isolate any layer to see it alone, and check every image asset's real format, size and transparency.
