Uploading files and adding context to a conversation

Claude can analyze not only text but also the content of uploaded files. Supported formats include: PDF, DOCX, CSV, TXT, HTML, as well as images in PNG and JPEG formats. When you upload a file, Claude automatically reads its content and considers it when answering your questions. This works as a shortcut: instead of explaining the entire context to Claude manually, you simply attach the relevant document. Practical examples of use: upload a document and ask to highlight key points, attach an image and ask to describe or analyze it, upload a spreadsheet and ask to find patterns in the data, attach code and ask to explain how it works or find errors. In addition to files, you can connect external data sources through connectors, as well as set persistent preferences in the "Settings" section so that Claude takes them into account in every response.
