12801280When an image is downsized, Claude scales it to the largest size that fits the tier's limits while preserving its aspect ratio. This caps the token cost. For the precise rule and a reference implementation, see [How Claude resizes and pads images](https://platform.claude.com/docs/en/build-with-claude/vision-coordinates#how-claude-resizes-and-pads-images).

1282To estimate cost, multiply the token count by the [per-token price of the model](https://claude.com/pricing) you're using. For example, at Claude Haiku 4.5's $1 USD per million input tokens (standard tier), the 1000×1000 image costs about $1.30 USD per thousand images. At Claude Opus 5's $5 USD per million (high-resolution tier), the same image costs about $6.48 USD per thousand and the 4K image about $23.92 USD per thousand.

12841284High-resolution images can use up to roughly three times more visual tokens than the same image on a standard-tier model. If you don't need the additional fidelity that high resolution provides for computer use, screenshot understanding, and dense documents, downsample images before sending to control token costs. To minimize latency and to simplify [coordinate-based workflows](https://platform.claude.com/docs/en/build-with-claude/vision-coordinates), prefer resizing images before uploading them.
