Building an Image to Text Converter with Next.js and Tesseract.js 🚀

Publish Date: Mar 16

Introduction

As developers, we often encounter challenges that inspire us to build solutions. One common problem I noticed was the need to extract text from images quickly and efficiently. Whether it’s scanning printed documents, extracting text from screenshots, or working with multi-language content, I needed a simple and effective solution. That's when I decided to create an Image to Text Converter using Next.js and Tesseract.js.

🧐 The Problem

OCR (Optical Character Recognition) technology is widely available, but many existing solutions are either too complex, require paid services, or don’t support multiple languages effectively. I wanted to create a tool that:

  • Is free and open-source
  • Supports multiple languages
  • Provides an easy-to-use UI
  • Allows exporting text in various formats
  • Works entirely in the browser without requiring backend processing

💡 The Solution

I built a Next.js application that integrates Tesseract.js, a powerful JavaScript OCR engine. The app allows users to upload images and extract text instantly, supporting multiple languages and various export options.

✨ Features

🌍 Multi-language Support

Extract text in multiple languages like English, Arabic, Spanish, French, and more.

📤 Export Options

Users can export the extracted text in .txt, .pdf, or .md formats.

🖼️ Image Upload

Supports file selection and drag-and-drop image uploads.

🔄 Image Preprocessing (Upcoming)

Enhances OCR accuracy with grayscale conversion and cropping.

🕶️ Dark Mode

A seamless light and dark theme experience.

📱 Responsive Design

Optimized for both mobile and desktop devices.

🛠️ Tech Stack

  • Frontend: Next.js, Tailwind CSS
  • OCR Engine: Tesseract.js
  • File Export: jsPDF

⚙️ How I Built It

  1. Setting Up Next.js
    • Installed and configured Next.js and Tailwind CSS.
  2. Integrating Tesseract.js
    • Used Tesseract.js to process images and extract text on the client-side.
  3. Building the UI
    • Created a user-friendly interface with drag-and-drop support.
  4. Adding Export Options
    • Implemented text, PDF, and Markdown export using jsPDF.
  5. Enhancing with Preprocessing (Upcoming)
    • Working on grayscale conversion and cropping for better OCR accuracy.

    I had trouble with blurry images reducing accuracy, so I added a basic canvas step to resize and sharpen before processing. It made a noticeable difference for image ocr. If you're getting inconsistent results, try cleaning the image a bit first—it helped me get cleaner text output, especially with screenshots or handwritten notes.
