How to Batch Convert Files for ChatGPT and Claude
Convert dozens of PDFs, Word docs and images into AI-ready text in one pass, entirely in your browser.
One folder, one pass
Converting files one at a time is tedious and error-prone. The Batch Document Extractor accepts a mixed batch and returns a ZIP with clean text for each file.
Organize before uploading
Group the outputs by topic and check total size with the Token Counter. Several focused uploads beat one giant dump.
- Rename outputs descriptively
- Delete duplicates and drafts
- Combine tiny related files
Good for knowledge bases
This workflow is ideal for Claude Projects, Custom GPTs, and RAG pipelines, where clean, consistent inputs directly improve retrieval and answers.
