Dropbox has announced the release of open source Lepton. This image compression format has been released under the Apache license.<\/p>\n

Lepton is not just a file format for losslessly compressing JPEGs by an average of 22%. It is also doubles as an image compression tool. Dropbox has been using this tool to compress billions of JPEG images hosted on their infrastructure saving them petabytes of storage space.<\/p>\n

What Lepton can Do No One Does it Better<\/h2>\n

Compressing JPEG files at 5 Megabytes per second, the tool is able to preserve the original file bit-for-bit without any loss of data. It is then able to decode the JPEG compression at a rate of 15 Megabytes per seconds with a minimal footprint of 24 MB.<\/p>\n

All this is done using some clever mathematical algorithms working with coefficients that are the result of a reversible transformations. It also leverages kernel-protected, read-only memory for compressed files to guarantee they are immutable during the full verification process.<\/p>\n

There is more to the entire process and Dropbox has this insightful blog post<\/a> that explains Lepton in finer details.<\/p>\n","protected":false},"excerpt":{"rendered":"
