Unlimited Image Translator: Translate Text in Images Automatically

Project Specifications & Benefits

• $0 Operational Fees: Deploys to Vercel's Hobby plan for free with no credit card registration.
• Unlimited Character & Image Limits: Tesseract.js runs OCR processing locally in browser memory, eliminating character limits and API caps.
• No CORS blocks: Directly utilizes Google's client-side translation endpoint with native origin-sharing support.
• Google Lens visual search integration: Forward local files programmatically to Google's search engine in a new tab with one click.

How It Works: Browser-Based OCR & Routing

Traditional image text extraction depends on costly backend cloud processors. By running Tesseract.js inside a dedicated web worker thread in the client browser, text characters are extracted locally. This text is then passed to Google Translate's public endpoint and mapped directly to the dashboard, preserving complete privacy:

Pipeline Architecture: Uploaded images are read via browser web workers, translated in real-time, and visual searches are forwarded to Google Lens.

Client-Side JavaScript Translation Logic

The Javascript handles processing local image files, running OCR, querying translation endpoints, and submitting files directly to Google Lens:

// Run OCR and Translation Client-Side

async function processTranslation() {

 const ocrData = await Tesseract.recognize(activeFile, 'eng+fra+spa+deu');

 const extractedText = ocrData.data.text.trim();

 

 const sl = document.getElementById("sourceLang").value;

 const tl = document.getElementById("targetLang").value;

 

 const url = `https://translate.googleapis.com/translate_a/single?client=gtx&sl=${sl}&tl=${tl}&dt=t&q=${encodeURIComponent(extractedText)}`;

 const res = await fetch(url);

 const data = await res.json();

 const translatedText = data[0].map(item => item[0]).join('');



 document.getElementById("translationResult").textContent = translatedText;

}



// Forward to Google Lens Search

function searchGoogleLens() {

 document.getElementById("lensForm").submit();

}

Deploying Your Image Translator to Vercel

Deploying your private image translator and lense search tool to the cloud requires zero manual configuration or coding. You can host it directly on Vercel using the 1-Click deploy integration below:

⚡ 1-Click Cloud Deployment (Recommended)

Clicking the button above will automatically clone the repository, preserve a clean short project URL, and configure it inside your Vercel dashboard.

Step-by-Step Instructions (How it works):

1. Create a free account on Vercel.com (signing in with your GitHub account is recommended).
2. Click the Deploy with Vercel button above. This redirects you to Vercel's template cloning page.
3. Vercel will prompt you to name your new GitHub repository. By using our deploy button configuration, the project name is pre-populated as unlimited-image-translator. Enter the name and click Create.
4. Vercel will automatically provision a new repository on your GitHub account, push the files, and serve your app on a clean, short unlimited-image-translator.vercel.app subdomain within a few seconds!

Terminal Output: Verification and packaging of the serverless image translator assets.
