This is something that could very easily be run locally, if it were a library. Libraries do the "heavy lifting" in most software. The only reason this is an api is so that you can charge people for each single use. While requiring an internet connection to work, and sending a copy of the file to your servers (unfortunately we live in a world where I cannot possibly trust any claims that data will be deleted within any timeframe). There is no conceivable reason for this to be a web api, imo.
