How file optimization works
Compared with traditional compression, File Optimization takes a different approach to tackling the problem of large files. Its remarkable performance stems from the fact that many large files, such as PDFs and Microsoft Office documents, contain a great deal of hidden bloat that can be stripped away or 'optimized' in order to reduce file size without changing the file format or affecting the visual integrity of the file.
File Optimization tackles individual elements inside a document, assessing how to reduce each component in turn. By examining each component in isolation it will choose the most effective method of reduction rather than applying general settings across the whole file. This approach creates much smaller files that remain in the same format, so no readers or decompression tools are required.
