Please take a look at the three PDF examples below, using information which we have gathered from publicly available websites (in this case, a public company’s financial releases which are always in PDF format).Ībove examples are of PDF files that can be compressed well and we estimate that an average PDF will be compressed between 30% and 50% (up to 85% if mostly text) when using reflate, while DOCX files which usually contain more text can be compressed up to 70% on average. In many cases, reflate will enable up to 50% better compression of these files, which is a significant feat that can’t be matched by any of our competitors such as WinZip or WinRAR.

Reflate can work up to 7 levels of nested deflate streams! For example, a ZIP file may contain a. With reflate, PowerArchiver will automatically detect files that can be pre-processed by reflate and use the reflate filter, without any interaction required by the user, to compress the formats even more! More advanced users can specifically select reflate to be applied on all of their files and test various different settings with it, to find the best compression rate and speed that works for them. Obvious examples are formats such as pdf, docx, xlsx, swf, png, zip, that use deflate as compression codec. It removes outdated compression used in these files and then restores it losslessly (without losing any data). Reflate is an advanced re-compression filter designed to improve the compression of files with deflate streams. The main requirement for reflate was to address the needs of today’s corporate environment, where the most used formats in exchange are PDF, DOCX and other Microsoft/Open Office formats. Reflate was designed in-house, by our compression engineer Eugene Shelwien.
During the talk, we will briefly touch upon the current de facto standard for image compression, a standard.
My name is Davide Concion and I manage the Image Compression Team at Apple. We are proud to introduce Reflate, the essential part of our new Advanced Codec Pack (.pa)!
