What Is OCR?
OCR (Optical Character Recognition) is a technology that reads text from images. It analyzes the shapes and patterns in a photograph or scan and converts them into machine-readable text that you can copy, edit, search, and paste.
Modern OCR engines like tesseract.js can recognize text in dozens of languages, handle various fonts, and process images of different quality levels. The technology works on photos, screenshots, scanned documents, handwritten notes, and more.
Why Extract Text from Images?
Image-to-text conversion solves everyday problems:
1. Digitize Printed Documents
Photograph a printed page, receipt, or form and extract the text for digital storage. This eliminates manual typing and creates searchable, editable records from physical documents.
2. Copy Text from Screenshots
When you see text in an image, error message, or screenshot that you cannot select, OCR extracts it for you. This is especially useful for text embedded in UI designs, charts, and infographics.
3. Translate Foreign Text
Photograph text in a foreign language, extract it with OCR, and paste it into a translation tool. This is faster and more accurate than typing unfamiliar characters manually.
4. Process Business Cards and Receipts
Extract contact information from business cards or expense data from receipts. OCR converts this information into text you can paste into spreadsheets, contacts, or expense reports.
How to Extract Text from an Image — Step-by-Step Guide
Convert image text to editable text in seconds:
Step 1: Open the OCR Tool
Navigate to the Extract Text (OCR) tool in any browser. No installation, plugin, or registration required.
Step 2: Add Your Image
Drag and drop your image — a photo, screenshot, scan, or any image with text — into the tool. Supported formats include JPEG, PNG, WebP, BMP, and more.
Step 3: Extract the Text
The OCR engine (tesseract.js) analyzes your image and identifies all readable text. Processing happens entirely in your browser — the image never leaves your device.
Step 4: Copy and Use
The extracted text appears in an editable text area. Copy it to your clipboard and paste it anywhere — word processors, emails, spreadsheets, or translation tools.
Tips for Better OCR Results
Use Clear, High-Resolution Images
OCR accuracy depends heavily on image quality. Use well-lit, focused photos with at least 300 DPI for printed documents. Blurry or low-resolution images produce lower accuracy.
Straighten the Image
Text at an angle or perspective is harder for OCR to read. Straighten your document or photo as much as possible before processing for the best results.
Maximize Contrast
Dark text on a white background produces the best OCR results. If your image has poor contrast, adjusting brightness and contrast before OCR can improve accuracy.
