The Read tool is the action Claude uses to open files. When Claude asks it for a whole PDF without naming any pages, and that PDF is over a certain file size and its page count is known, Claude Code can now read it as a page range covering page 1 through the last page. Each page then reaches Claude as an image.
A second switch can add the text extracted from each page alongside its image. That text is left out when adding it would make the result larger than a size limit.
Both switches are off unless they are turned on remotely. A separate switch, also off by default, still decides whether a PDF with too many pages returns its first pages instead of an error.
This changes the form in which big PDFs reach Claude: as page images, with the page text attached when that option is on. Because it is switched on remotely, the same PDF may be read differently from one account to another.
