Fuji OCR: A 100% Local, Privacy-Focused Screenshot OCR Chrome Extension

Introduction

We often need to copy text from images, videos, or protected websites. However, many people hesitate to use online OCR tools due to privacy concerns about uploading sensitive images to external servers.

Enter Fuji OCR, a Chrome extension designed to solve this exact problem. Its standout feature is that 100% of the OCR processing happens locally on your device using WebAssembly. No images or extracted text are ever sent to any server.

In this post, I'll walk you through the key features and how to use Fuji OCR effectively.
