About EasyLottie
EasyLottie is an independent project that builds focused browser tools and tested guides for people who work with Lottie animation files.

What EasyLottie does
Designers receive Lottie files they cannot open in a motion tool. Developers receive animations with the wrong brand color, a placeholder logo, or a file size that blows the bundle budget. EasyLottie exists for that last mile: open the file, change the one thing that is wrong, export, and move on.
Each tool does one job. The viewer plays JSON, ZIP, and .lottie files and shows layer and asset data. The color changer detects every color in a file and lets you swap palettes. The image replacer swaps embedded bitmaps. The compressor reduces JSON size without touching keyframes. The GIF exporter and the video converter move animation between formats and explain, on the page, what each format cannot do.
Who builds it
EasyLottie is built and maintained by one independent developer. It is not owned by an animation marketplace, a design-tool vendor, or an agency. There is no sales team and no investor roadmap; features are added when a repeated user problem shows up in feedback, support emails, or aggregate analytics.
Because one person maintains the site, the scope stays deliberately small. We would rather ship six tools that are verified against real files every release than thirty that are not. Every refactor is re-tested with a set of real Lottie files in the uploaded state, not just the empty landing state.
How the tools work
Core file processing runs inside your browser. Parsing, preview rendering, color detection, image replacement, compression, GIF encoding, video decoding, and chroma keying all execute locally with WebCodecs, WebGL2, and standard JavaScript libraries. Unpublished artwork and client assets stay on your device unless you explicitly choose an action that uploads them.
Three features do use a server, and each says so on its page: optional accounts and cloud sync (so a result can be reopened on another device), share links (which store the shared result), and the AI image-to-Lottie generator (which sends your uploaded image and prompt to a model and returns animation data). Nothing else leaves the browser.
Each tool page lists its accepted formats and its known limits. When a conversion is lossy or cannot do something — video does not become editable vectors, GIF cannot keep soft edges — the page says so above the tool rather than in a footnote.
How the site is funded
All tools are free and there is no paid tier. The project is funded by its maintainer. Guide pages may carry advertising; tool workspaces never do, and ads are kept away from upload, playback, export, and download controls so they cannot be mistaken for part of the tool. Advertising has no influence on which workflow a guide recommends — see the editorial policy.
How the product is maintained
We review product analytics in aggregate, investigate repeated failures, test representative Lottie files, and update guides when browser capabilities or file workflows change. Analytics events use coarse technical attributes such as a file extension or size bucket. EasyLottie does not send file contents or file names to analytics.
Guides are based on workflows that can be reproduced with the tools on this site. The editorial policy explains how articles are written, checked, updated, and corrected, and every guide shows the date it was last reviewed.
History
- July 2025. EasyLottie starts as a single-page static toolbox with a Lottie viewer, a color changer, and an image replacer. The goal was narrow: fix a delivered Lottie file without reopening After Effects.
- Late 2025 – early 2026. V1.2.x adds ZIP support, dark mode, Chinese and English UI, GA4 instrumentation, and the first SEO pass. All processing still runs in the page itself.
- May 2026. The site is rebuilt on Next.js (V2.0) with a design-token system so the tools and the guides share one shell. The tool pages are ported one at a time; business logic is kept identical and re-verified with real files.
- June – July 2026. Figma animation to Lottie, SVG color changer, and the AI image-to-Lottie generator ship. Optional accounts and a workspace arrive so results can be saved and shared by link.
- August 2026. Lottie compressor, Lottie to GIF, and six additional interface languages. The guide library is audited and the six most-read guides get real screenshots, measured results, and reviewed dates.
- September 2026. Video tools: MP4 / MOV / WebM to image-sequence Lottie, a Keylight-style chroma key, transparent WebM and GIF export, PNG sequences, and MP4 to GIF. A research page publishes statistics from a corpus of real Lottie files.
- October 2026. V3.7 redesign: tool-first layouts, a unified post-upload workspace, and neutral typography. The language set in search is narrowed to English, Chinese, and Russian until the other locales carry real copy.
Who EasyLottie is for
- Product designers checking animation handoffs and fixing colors or assets before review.
- Frontend and mobile developers validating Lottie assets and trimming file size before they ship.
- Motion designers making small delivery changes without reopening a full authoring project.
- Teams comparing JSON, ZIP, .lottie, GIF, WebM, and video-based delivery options with real exports.
- People with an AI-generated or green-screen clip who need a transparent asset for a web page.
What EasyLottie is not
It is not a Lottie marketplace and does not host a library of other people's animations. It is not a full keyframe editor; if you need to redraw shapes or retime a complex rig, use After Effects, Figma, or another authoring tool and bring the export here. It does not turn video into vector Lottie — no browser tool does — and it will not claim otherwise.
