The first article of our PDF Optimization In-depth Series is available here. The PDF format is interactive. During the release cycle of a PDF document, different people will use tools such as forms, annotations, attachments, and more. Archived PDF documents generally do not have the same use as those in circulation in a collaborative context. […]
Here are the links for the two previous articles of the series: A PDF document is composed of various data structures, described as different objects. In the scope of optimization, one is particularly important: the stream object. This object aims to store binary data representing the content of an image, font file, color profile, embedded […]
Organizations often find that information governance is a complex subject, as it covers a lot of domains. The PDF format can help simplify processes thanks to its many features such as digital signing, compression, redaction, encryption, and tags, to name a few. Favoring PDF/A for archives also helps with compliance as it is an ISO […]
Previously in the PDf Optimization In-depth Series. Resizing images Resizing images can provide significant gains in occupancy. For example, decreasing unnecessary high resolutions can dramatically reduce the file size without affecting the viewing experience. But sometimes it is also a pretty destructive approach. There exist many sophisticated resizing algorithms, but it is rare to obtain […]
Previously in our PDF Optimization In-depth Series: MRC compression in PDF documents is highly efficient in file size reduction without visible degradation of document rendering. MRC, also known as hyper-compression, is an image compression benefiting from image segmentation methods. It is particularly useful for images containing text and continuous-tone graphics. This method reduces the size […]
Previously published in the PDf Optimization In-depth Series: Sometimes, when acceptable or necessary, it may be interesting to recompress images already included in an existing PDF file to reduce the file size. The PDF specification allows for seven compression schemes for such purposes. All of them can be used to compress images. Among these different […]
