Journal Impact is an online information platform focused on journal rankings and publication metrics. It helps readers explore journals by subject and compare measures such as impact scores and quartiles. The site organizes coverage across a broad range of fields, including medicine, engineering, environmental science, business, computer science, arts and humanities, and physics, with additional subject-level categories for more targeted browsing.

Its main resource is a subject-organized list of journals that displays titles, ISSNs, categories, and impact scores. The published examples span prominent medical, scientific, technical, and social science journals, allowing users to scan rankings across disciplines. The site also presents information about journal impact factors and describes its latest list in relation to Clarivate’s Journal Citation Reports, while distinguishing impact scores from other journal metrics.

Journal Impact offers a journal finder app, with a QR code and download prompt shown on the site. Navigation includes About and Contact sections, alongside tools and subject menus intended to make journal metrics easier to find and review.
