1. A method for determining accurate document transformation, the method comprising: queuing, by one or more processors, a source document for transformation to a target document according to an assigned priority for the target document, wherein the assigned priority is based on a descending order of file sizes for target documents of queued source documents; responsive to determining the source document is next in the queue, transforming, by one or more processors, content of the source document into the target document, wherein transforming the content of the source document includes transforming the content from the first format to the second format; responsive to determining an increased likelihood the source document was not accurately transformed to the target document based on a file size for the target document, rendering, by one or more processors, the source document into a non-rasterized graphical format, wherein a rendered source document represents the source document in the non-rasterized graphical format; and determining, by one or more processors, based at least in part on a comparison of one or more aspects of the rendered source document and a rendered target document in a non-rasterized graphical format, the source document was accurately transformed to the target document.
