  1. How does a PDF Compressor Work?

  2. What is a PDF compressor? A PDF compressor is a tool that reduces the size of a file. By doing so, users are now allowed to send that file through email (which can usually hold only up to 25MB) and upload online.

  3. Why do we need to compress? Other than the online requirements, having a small file size is also necessary for printing and transferring, which is also resolved by compressors.

  4. How does it work? When using online PDF compressors, the original PDF file is still intact and all the information is still the same. So how does it make it smaller? The compressor basically rearranges the codes, removes duplicate data, and fix disorganized information inside to make it much more efficient for storage. For some compressors, there are additional options that make it more optimized such as lowering image file size and converting images into grayscale. Since photos and media are often the reason for large file size, it is often the one affected when compressor tools begin the process.

  5. How DeftPDF compressor works? • Just like our PDF compressor here at DeftPDF.com, there is also an option to optimize images according to your preference such as selecting image quality, changing image resolution, or turn it into grayscale if you really need the PDF to be smaller in size.

  6. What are the two kinds of compression?

  7. 1. Lossless With the term lossless itself, you can actually conclude that lossless means no data, and quality is removed from the file. This is used for text documents and PDF files. In this method, the compressor usually recognizes the algorithm in the file, creates reference points for patterns, and reorganizes it for efficient storage.

  8. 2. Lossy On the other hand, lossy means quality may be compromised. Though this is the case, it's not for all kinds of files as lossy types of compressions are usually used for images and graphics. When this process takes place, bits of information are deleted and therefore provides a low-quality output.
