Faster DOCX Conversion Process

Sometimes, the converted document size may be larger than the original, resulting in longer conversion times. To address this, the document conversion library includes a caching feature to optimize the repetitive conversion process. By implementing the ICache interface through the extension point, developers can customize the cache and manage the conversion process efficiently. With this feature, you can speed up the repetitive DOCX conversion process and control the cache conversion as needed.

The conversion result is saved to the local drive by default but any type of cache storage can be supported by implementing the appropriate interfaces such as Amazon S3, Dropbox, Google Drive, Windows Azure, Reddis or any other.
