Have a chart image but need the raw data? Whether it's a screenshot from a PDF, a slide from an old presentation, or a chart you found online, AI can now extract the underlying data for you—no manual typing required.
When Is This Useful?
You might need to extract data from chart images when:
- You have screenshots from old reports and lost the original spreadsheet
- You're analyzing competitor charts from their website or reports
- You received a PDF presentation and need to recreate the charts
- You want to update an old chart with a fresh design
- You're doing research and found charts in academic papers
Step 1: Upload Your Chart Image
Go to PrettyChart and upload your chart image. You can drag and drop it onto the page, or use the upload button. PrettyChart automatically detects that it's an image and triggers AI extraction.
Supported formats include:
- PNG, JPG, WebP images
- Screenshots from any device
- Cropped charts from PDFs
Tip: For best results, crop the image to show only the chart itself—remove headers, footers, and other text around it.
Step 2: Let AI Extract the Data
Once you upload the image, PrettyChart's AI analyzes it and extracts:
- Chart type – Identifies if it's a bar chart, line chart, pie chart, etc.
- Labels – Reads the category names (x-axis labels or legend items)
- Values – Extracts the numeric data from the chart
The process takes just a few seconds. You'll see a preview of the extracted data in a spreadsheet format.
Step 3: Review & Edit the Data
AI isn't perfect—especially with blurry images or complex charts. Take a moment to review the extracted data:
- Check that all labels were read correctly
- Verify the numeric values match what you see in the image
- Add or remove rows if the AI missed something
The built-in spreadsheet editor makes it easy to correct any mistakes before moving on.
Step 4: Recreate as a New Chart
Now comes the fun part. With your data extracted and verified, you can create a brand new chart with a professional look:
- Choose from 18 chart types
- Apply one of 30 professional templates
- Pick a color theme that matches your brand
- Add effects like glow, shadows, or patterns
- Export as PNG, SVG, or PDF
The result? A presentation-ready chart that looks far better than the original screenshot.
Limitations & Tips
AI extraction works best with certain types of charts. Here's what to keep in mind:
- Clear bar charts (horizontal and vertical)
- Simple line charts
- Pie and donut charts
- High-resolution images
- 3D charts with perspective
- Charts with gradient or textured backgrounds
- Low-resolution or blurry images
- Charts with many overlapping elements
Pro tip: If extraction isn't accurate, try cropping the image more tightly around just the chart area, or use a higher-resolution version if available.
Frequently Asked Questions
Can AI extract data from any chart image?
AI works best with clear, high-resolution images of common chart types like bar charts, line charts, and pie charts. Complex 3D charts or heavily stylized graphics may have lower accuracy.
Is my chart data private when using AI extraction?
When using AI extraction, your image is sent to a secure AI service for analysis. The data is processed but not stored. All subsequent chart editing happens locally in your browser.
What if the AI makes mistakes in the extracted data?
After extraction, you can review and edit the data in the built-in spreadsheet editor. Simply correct any values that the AI misread before creating your new chart.
