YandexImageResizer is a Yandex service crawler that retrieves images to generate resized, optimized, or cached versions for use in Yandex search results and related products. It fetches original image files to create thumbnails or alternative resolutions suited for different devices and interfaces. This crawler does not perform full page indexing and does not independently rank content. Crawl activity is lightweight and asset-specific, typically triggered when Yandex needs to update or regenerate image variants to improve load performance and visual presentation across its platforms. YandexImageResizer honours the global robots.txt user agent (*) rule. RobotSense.io verifies YandexImageResizer using Yandex’s official validation methods, ensuring only genuine YandexImageResizer traffic is identified.

This bot does not honor Crawl-Delay rule.
