OCR (Image → Text)
Use Tesseract.js to extract text from images directly in the browser.
OCR – Image to Text, Local Processing
Convert scanned images or photos of documents into editable text using Tesseract.js running in your browser. MiniAIToolset's OCR tool offers an accessible and private way to recover text from receipts, scanned pages, and screenshots without sending images to external servers. It supports common languages and provides a quick workflow for extracting editable text that can be reviewed, copied, and summarized using our AI Summarizer.
Why OCR in the browser
- Privacy-preserving: Images are processed locally by Tesseract.js.
- Convenience: Extract text without installing desktop OCR software.
- Integration: Combine OCR with the Summarizer to get instant highlights from scanned sources.
Use cases
Digitize receipts for expense tracking, extract contact information from business cards, convert meeting whiteboard photos to text, or prepare scanned contracts for editing.
How to run OCR
- Upload an image (photo, scanned page, or screenshot) using the file selector.
- Select the language for OCR if available (English by default).
- Click 'Run OCR'. The engine will process the image and output recognized text into the result area.
- Copy or export the text for editing, summarization, or archival.
OCR tips
- Ensure images are clear and well-lit — high-contrast, straight scans yield the best results.
- For multi-page documents, process pages individually or use a PDF-to-image step before OCR.
- Handwritten text has significantly lower recognition accuracy compared to printed text.
Extract text from images privately in your browser and accelerate document workflows with local OCR processing.
Frequently asked questions
Which languages are supported?
The tool includes common languages via Tesseract.js. Select your desired language before running OCR. Availability depends on included language packs.
Is handwriting supported?
Handwriting recognition is limited and generally less accurate than printed text recognition.
Do images get uploaded to a server?
No. The OCR engine runs in your browser and images are not transmitted to external servers.
How can I improve OCR accuracy?
Use high-resolution images, crop unnecessary borders, and ensure text is horizontally aligned where possible.
Can I OCR a multi-page PDF?
Convert PDF pages to images first (e.g., export pages as PNG) and then run OCR on each image for best results.
Is OCR fast?
Speed depends on image size and device performance. Typical single-page OCR completes in seconds on modern devices.
Can I copy the extracted text?
Yes — the recognized text appears in the result area and can be copied to the clipboard.
