Enter —a brilliant, yet lesser-known, image compression tool developed by Google (specifically, the team behind Dropbox’s image optimization research). Unlike standard JPEG compressors that strip metadata or lower quality, Lepton uses a sophisticated predictive coding method to losslessly compress JPEGs by an average of 22% .

A standard web browser read a .lep file. You cannot just upload .lep images to WordPress or a static HTML page.
To get your original JPEG back (perfectly restored): A standard web browser read a
In the world of web performance, every kilobyte counts. Large, uncompressed images are often the #1 culprit behind slow loading times, high bounce rates, and poor SEO rankings.
git clone https://github.com/dropbox/lepton.git cd lepton cmake . make Once downloaded, open your terminal (Command Prompt on Windows, Terminal on Mac/Linux) and navigate to the folder containing your images. 1. Basic Compression (JPEG to LEP) To compress a single image: Large, uncompressed images are often the #1 culprit
lepton input.jpg output.lep Expected result: You will see a output.lep file that is roughly 22% smaller than input.jpg . Use a simple loop to compress everything:
