How to use Claude for OCR
- On claude.ai, upload the image like any file, or drag it into the chat window[2]. You can also paste from the clipboard[1].
- Ask for the full text of the page, line by line, or as a table.
- Copy the answer from the chat.
Claude takes JPEG, PNG, GIF and WebP images, and PDF, DOCX and other documents[1]. For the best reading, Anthropic recommends images of 1000 by 1000 pixels or larger[1].
What limits does Anthropic list?
- Files per chat
- Up to 20[1]
- File size
- 500 MB per file in a chat, 30 MB per project file[1]
- PDF pages
- Up to 1,000 pages[1]
- Scanned PDFs
- Visual elements read only in PDFs of 100 pages or fewer[1]
That last line matters for OCR. A scanned PDF is made of page images. Anthropic's help page says that for PDFs from 101 to 1,000 pages, Claude processes text only and does not analyze visual elements[1]. A 150-page scan with no text layer gives it nothing to read, so split it into parts of 100 pages or fewer before you upload it.
Can Claude read handwriting?
Claude reads handwriting in a photo as part of the image, the same way it reads print. Anthropic's vision guide lists the cases where it can make mistakes: low-quality, rotated, or very small images under 200 pixels[2]. A sharp, upright photo of each page gives it the best start.
For a whole notebook of lecture notes, LoreAI reads every page in one upload and returns one Word file in the original order, with headings and lists kept. See handwriting to text and the best handwriting OCR.

When to use Claude, and when a document OCR
- Use Claude to ask about a page: what a chart shows, what a clause means, what a set of notes says in short.
- Use Claude when the text is a step toward an answer, not the thing you keep.
- Use LoreAI when you need the document back as a document, every line in order and the tables as tables, ready to edit in Word.
- Use LoreAI for a long scan in one upload, up to 100 pages on Pro.
