How to Use
Upload Image
Select or drag-and-drop your image file. You can also paste an image from your clipboard. Supported formats include PNG, JPG, WebP, and BMP.
Choose Language
Select the language of the text in your image from the dropdown. The OCR engine will download the necessary language data on first use.
Configure Advanced Options
Set the number of parallel OCR workers, enable preprocessing filters (grayscale, threshold, denoise), and define zone regions by drawing bounding boxes on the image preview.
Configure Options
Adjust Page Segmentation Mode to match your document layout. Enable grayscale conversion or adjust the threshold for better results on challenging images.
Extract Text
Click Extract Text to run OCR. The first run will download the OCR engine and language data (may take a few seconds). Subsequent runs are faster.
Batch Process
Add multiple images to the batch queue and process them all at once. Each result appears in its own tab for side-by-side comparison and individual export.
View Results
Review the extracted text in the Plain tab. Switch to JSON for structured output with bounding boxes and confidence scores, or HOCR for layout-preserving HTML. If table structure is detected, switch to the Table tab to see it as an HTML table.
Export Your Data
Copy text to clipboard, or download in your preferred format — plain text (TXT), JSON with word coordinates, HOCR, searchable PDF with invisible text overlay, or CSV when table data is available.
How to Calculate
Text is recognized with Tesseract OCR running locally: deskew and contrast options clean the image, multi-worker mode splits pages across cores, and each word ships with a confidence score plus bounding box for review.
About the Image to Text (OCR) Tool
The Image to Text (Advanced OCR) tool uses Tesseract.js — a 100% client-side OCR engine — to extract text from images right in your browser. No images are ever uploaded to any server.
New advanced features include multi-worker parallel OCR for faster, more accurate results; batch processing for handling multiple images at once; zone/layout selection for targeting specific regions; preprocessing presets (Document, Receipt, Screenshot, Handwriting); auto deskew and manual rotation correction; searchable PDF export with invisible text overlay; and automatic table detection with CSV download. Output can be downloaded as plain text, JSON with bounding boxes, hOCR, searchable PDF, or CSV.
OCR runs locally after the model loads, so scanned pages stay with you. For best accuracy use clear contrast scans, then copy and proofread the extracted text.
