History

Explore the timeline of JPEG XL’s development and the key milestones that have shaped its evolution.

In 2010, a Paris-based Google team created lossy WebP as single-frame WebM (VP8).

In 2012, the Zurich-based Google compression team lead by Jyrki Alakuijala added alpha support and a lossless mode to WebP.

They went on doing other things:

In 2017, they released the first version of Pik.
2017
End of 2017, JPEG started drafting a Call for Proposals for JPEG XL. Jon Sneyers starts working on FUIF, the Free Universal Image Format, based on FLIF.

Early 2018: JPEG launches Call for Proposals for a next-gen image codec (‘JPEG XL’)

In September 2018, Google submits Pik to the JPEG XL Call for Proposals.
In September 2018, Cloudinary submits FUIF to the JPEG XL Call for Proposals.
Combining Pik & FUIF
It took almost two years to combine Pik and FUIF
  • September 2018: 7 proposals submitted to the JPEG XL CfP, including Pik and FUIF
  • October 2018: The JPEG committee investigates the different proposals
  • January 2019: Combination of Pik+FUIF selected
  • Two years of shared development, many improvements made along the way
