How does PDF compression work? The SaferPDF difference

Have you ever wondered how a PDF compressor works and manages to keep all of your file’s information intact whilst making it weigh less? If not, you are about to (you’re welcome!). In this blog post, we’ll share the ins-and-outs of PDF compression, so you can impress your in-laws at your next awkward dinner party. We’ll also explore what sets SaferPDF’s browser-side compressor apart from the competition, as the ultimately safest solution on the PDF market.

Understanding PDF compression

At its core, PDF compression involves removing redundant data and optimising file elements to decrease the overall size of a PDF document. This process typically targets non-essential components (don’t come for us dear designers!) such as embedded fonts, images, and metadata, without compromising the readability or integrity of the document.

How traditional PDF compressors work

Traditional PDF compressors operate by analysing the structure and content of a PDF file and applying compression algorithms to reduce its size. These algorithms can be either lossy or lossless, depending on whether they sacrifice some quality for greater compression efficiency. “Lossy? What kind of word is that?” Let us break it down for you.

• Lossy compressions are also commonly known as irreversible compressions, meaning that when the algorithms go through the file and look for elements to delete to reduce the overall weight of the document, they delete parts of the original data… permanently. Lossy compression is not necessarily visible to the naked eye (unless abused) and is mostly used to compress images, video files and other media files.

• Lossless compression on the other hand removes unnecessary metadata and rebuilds the original file after the process of elimination. Also known as reversible compression, this type of process is used on files that just cannot lose an ounce of their data.
