Claude Code has introduced a method that reduces input token costs by converting text to images. This approach utilizes a local proxy called pxpipe, which transforms large text blocks into compact PNGs, significantly lowering processing costs during interactions with the model.
Claude Code has implemented a novel approach to manage input tokens more efficiently. By using a local proxy named pxpipe, text requests that are typically bulky can be rendered as images, allowing for reduced token usage during model processing.
The key advantage of this method is the fixed cost of image tokens based on pixel dimensions rather than text length. This results in a higher character-density per image token (approximately 3.1 characters) compared to standard text tokens (about 1 character).
The transformation of around 25k text tokens into roughly 2.7k image tokens exemplifies the efficiency of this approach. Measured actual costs indicate a reduction of approximately 59–70% in end-to-end billing when using pxpipe for token-dense queries.
This solution is particularly beneficial for those who handle complex requests with dense data formats like code or JSON. Although savings can depend on workload type, the overall strategy presents a significant opportunity for cost reduction in using Claude Code.
