Lottie Animation Community to Present at Open Source Summit Europe 2025

Wed, 30 Jul 2025 12:01:01 GMT

The Lottie Animation Community (LAC) will be presenting at Open Source Summit Europe 2025 in Amsterdam, scheduled for August 25-27, 2025.

Our session will detail the process of establishing the Lottie 1.0 specification under the Linux Foundation. We will discuss the technical challenges encountered during the standardization of the format, focusing on achieving cross-platform compatibility and consistent feature rendering.

The presentation will cover the collaborative effort involved in developing an open specification, which incorporated input from various industry stakeholders. Topics will include key components of the Lottie format, the standardization work undertaken to improve interoperability between creation tools and rendering engines, and demonstrations of the format's capabilities through practical applications. We will also provide an overview of future initiatives and invite further collaboration.

Speakers for this session include:

Mattia Basaglia, Principal R&D Engineer, LottieFiles.
Brandon Wilson, Senior Software Engineer, Google.

We look forward to sharing these developments with the open-source community in Amsterdam.

Lottie Animation Community Achieves Formal Recognition from IANA and IESG

Mon, 24 Feb 2025 12:13:57 GMT

The Lottie Animation Community (LAC) announces the formal assignment of ".lot" file extension and the "video/lottie+json" MIME type with the Internet Assigned Numbers Authority (IANA). This registration establishes a formal standard for identifying and handling Lottie animation files.

Additionally, the Lottie Animation Community has received recognition as an authority by the Internet Engineering Steering Group (IESG).

The formal registration of both the ".lot" extension and the "video/lottie+json" MIME type by IANA significantly contributes to the standardization, interoperability, and overall adoption of the Lottie animation format. It allows for smoother integration and a more reliable user experience across different platforms and applications.

Recognition by the IESG acknowledges the Lottie Animation Community's efforts in developing and maintaining standards for Lottie animations. This acknowledgement reinforces the community's commitment to open and accessible animation technology.

Lottie Animation Community announces Lottie v1.0 specification

Tue, 17 Sep 2024 12:01:01 GMT

Lottie Animation Community announces Lottie v1.0 specification

The Lottie Animation Community (LAC), a Joint Development Foundation project, is pleased to announce the release of the v1.0 Lottie JSON specification. This marks a significant milestone in our efforts to establish the Lottie File Format as an open standard for efficient, scalable, and cross-platform animated vector graphics.

The v1.0 specification lays the foundation for future advancements, with a clear roadmap guiding the ongoing development of the format. We invite creators, implementers, and the wider community to explore the specification, contribute to its evolution, and help shape the future of animation technology.

For more details on the v1.0 specification and what lies ahead, visit https://lottie.github.io/changelog/.

About Lottie v1.0

Version 1.0 of the Lottie Animation Format is the result of the collaborative work of many Lottie stakeholders, starting with the formation of the Lottie Animation Community and its working group. The goal of v1.0 is to include all well known, commonly implemented, documentable features, to establish a foundational baseline for the format and setting the stage for future iterations. Features that are not widely supported will not be in the v1.0 specification, but implementers are encouraged to use it as a baseline and propose additions for an upcoming revision.

Lottie Animation Community announces public review draft of Lottie v1.0 specification

Lottie Animation Community announces public review draft of Lottie v1.0 specification

The Lottie Animation Community (LAC), a Joint Development Foundation project, is pleased to announce the public review draft of the v1.0 Lottie JSON specification. v1.0 will be the first major step in securing the Lottie File Format as an open standard for efficient, scalable and cross-platform animated vector graphics.

The public review period for the Lottie v1.0 draft will be from August 6 to September 3, 2024. We request all significant changes be proposed by August 26 to allow for final review and publishing. Review the documentation here and validate your existing Lotties here. Participate in the review by opening github issues for the spec here.

About Lottie v1.0

Version 1.0 of the Lottie Animation Format is the result of the collaborative work of many Lottie stakeholders, since the forming of the Lottie Animation Community and working group. The goal of v1.0 is to include all well known, commonly implemented, documentable features, to establish a baseline for the format and pave the way for future iterations. Features that are not widely supported will not be in the 1.0 specification but may be added in a later revision. We envision implementers may want to declare a profile referencing the spec version, to allow for some variance in feature support while driving API consistency and schema reliability.

Lottie as a standard with Lottie Animation Community (LAC) format specification body

Wed, 31 Jan 2024 12:01:01 GMT

We are excited to announce the Lottie Animation Community (LAC), a non-profit open source project hosted by The Linux Foundation, dedicated to establishing the Lottie File Format as an efficient, scalable and cross-platform animated vector graphics technology and open file format.

The evolution and prevalence of Lottie has prompted the need for a formal format specification and democratic change mechanism, to help developers and consumers of the format ensure reliable performance and compatibility across the diverse platforms on which Lottie is used.

LAC was founded by a community of pioneers in recognition of that need. LAC aims to develop a formal Lottie format specification for implementation across renderers and other tools, and works towards the promotion and widespread adoption of the Lottie file format as an industry standard.

LAC operates as a project under the governance of the Joint Development Foundation, guaranteeing an open, collaborative approach to our standardization efforts. Our work is deeply rooted in transparency, ensuring that everyone in our community has a voice in the development and refinement of the Lottie File Format.

The current LAC steering committee members are Hernan Torrisi, Google, LottieFiles, Airbnb, Salih Abdul-Karim and Gabriel Peal. Our community is growing with new members such as LottieLab, who share our commitment to the advancement of the Lottie File Format.

We invite like-minded organizations and individuals to join us at github.com/lottie

Together, we can make the digital world a more animated place.
