how many documents can i upload to the free version of claude

Claude’s free version appears to allow up to 20 documents/files per chat , based on the current help-center limits. Each file can be quite large in chat uploads, but the total usable amount still depends on the conversation’s context limits.

What matters most

• Per chat: up to 20 files.

• Per file: up to 500 MB in chat uploads.

• Projects: files can be unlimited , but the content Claude can actually use is still limited by the context window.

Practical takeaway

If you’re using Claude Free for one-off analysis, think of 20 files as the hard chat limit , not the total amount of text Claude can digest. Bigger files, especially PDFs and spreadsheets, may hit practical limits sooner because of the amount of extracted text.

TL;DR: Free Claude chat uploads are capped at 20 documents/files per chat.
