Screenshot Text Recognition: How to Quickly Extract Text from Screenshots
Learn how to extract text from screenshots, including OCR recognition methods for computer and mobile screenshots, and tips for improving screenshot text recognition accuracy.
Why Screenshot Text Recognition?
In daily work and study, we often need to extract text from screenshots:
- Copy text from web pages that can't be selected (like text in images, scanned PDFs)
- Extract subtitles or text information from videos and live streams
- Save chat records, comments, and other content
- Extract data from software interface screenshots
- Organize text notes from online courses and presentations
Manual typing is time-consuming and error-prone. OCR technology can complete text extraction in seconds.
Computer Screenshot Text Recognition Methods
Method 1: Use EasyOCR Online Recognition
The simplest way, no software installation needed:
- Use system screenshot tool to capture screen content
- Open EasyOCR Online Recognition
- Paste screenshot directly or upload image file
- Click recognize, get text in seconds
Method 2: System Screenshot Shortcuts

Mac:
Cmd + Shift + 4- Capture selected areaCmd + Shift + 3- Capture full screenCmd + Shift + 4 + Space- Capture current window
Method 3: Browser Extensions
Install OCR browser extensions to select and recognize text areas directly on web pages without saving screenshot files.
Mobile Screenshot Text Recognition
iPhone / iPad
iOS 15 and above has built-in "Live Text" feature:
- Open image after taking screenshot
- Long press on text in image
- System will automatically recognize and allow selection and copying
If system version is older or recognition isn't working well, use EasyOCR web version.
Android
Some Android phones have built-in text recognition. You can also:
- Open easyocr.org/ocr in browser after taking screenshot
- Upload screenshot for recognition
Tips for Improving Screenshot Recognition Accuracy
1. Screenshot Clarity
- Use original resolution screenshots, avoid scaling
- For web content, zoom in on page before taking screenshot
- Avoid capturing blurry or low-resolution content
2. Capture Range
- Only capture the text area that needs recognition
- Avoid including too many images, icons, and other interfering elements
- Ensure sufficient contrast between text and background
3. Special Cases
- Dark mode screenshots: Recognition usually works fine, no special processing needed
- Color backgrounds: If recognition is poor, convert to grayscale first
- Artistic fonts: May have lower accuracy, recommend manual proofreading
Common Screenshot Recognition Scenarios
Scenario 1: Copy Text from Web Images
Many websites make text into images to prevent copying. Screenshot + OCR can easily extract it.
Scenario 2: Extract Video Subtitles
Pause video, capture frame with subtitles, then use OCR to recognize subtitle text.
Scenario 3: Save Social Media Content
Long posts on social platforms are more convenient to capture and OCR recognize than manual copying.
Scenario 4: Organize PPT/PDF Content
For scanned PDFs or image-format presentations, screenshot recognition is the fastest text extraction method.
Scenario 5: Game/Software Interface Text
Extract text information from game guides, software settings, and other interfaces.
Screenshot Format Selection
Impact of different screenshot formats on OCR recognition:
| Format | Characteristics | Recommended Scenario |
|---|---|---|
| PNG | Lossless compression, highest quality | First choice, suitable for all scenarios |
| JPG | Lossy compression, smaller files | Photo-type screenshots |
| WebP | Modern format, balanced quality and size | Web screenshots |
| BMP | No compression, very large files | Not recommended |
PNG format is recommended to maintain best text clarity.
Batch Screenshot Recognition
If you need to recognize many screenshots:
- Save all screenshots to one folder
- Use batch processing solution to call API for batch recognition
- Export results to text files or spreadsheets
API Call Example
Developers can automate screenshot recognition via API:
// Get screenshot from clipboard and recognize
async function recognizeFromClipboard() {
const clipboardItems = await navigator.clipboard.read();
for (const item of clipboardItems) {
if (item.types.includes('image/png')) {
const blob = await item.getType('image/png');
const formData = new FormData();
formData.append('file', blob, 'screenshot.png');
const response = await fetch('https://api.easyocr.org/ocr', {
method: 'POST',
body: formData
});
const result = await response.json();
console.log('Recognition result:', result);
}
}
}FAQ
Q: Can tables in screenshots be recognized?
Text in tables can be recognized, but table structure may not be fully preserved. Recommend capturing and recognizing by region.
Q: Can handwritten text in screenshots be recognized?
Yes, but accuracy depends on handwriting clarity. Neat handwriting recognizes well.
Q: What if recognition results have garbled text?
May be due to low screenshot resolution or text being too small. Try zooming in and retaking screenshot.
Summary
Screenshot text recognition is one of the most common OCR use cases. With EasyOCR, you can quickly extract text from any screenshot without installing software - just open your browser. Try screenshot text recognition now and say goodbye to manual typing.
