PDF processing

Claude models can analyze both text and visual elements (like images, charts, and graphics) in PDFs that are under 100 pages. Claude will only process text from PDFs over 1000 pages.

Tips for best results

For images: Use images that are 1000x1000 pixels or larger. Avoid small or low-resolution images where possible.

For PDFs: When referring to specific pages, use the PDF page numbers as shown in your PDF viewer, not the page numbers printed on the document itself.

For large documents: If you're working with larger files, consider dividing them into smaller sections to stay within limits.

For non-PDF documents: Claude extracts text only from these files. If they contain embedded images, Claude won't be able to read or interpret them.
