How to Create Chart Images at imgresizr.com
Create your chart data in a spreadsheet tool first, then take a screenshot of the chart and upload to imgresizr.com. Use the Enhance tool to sharpen text and ensure colours are vivid. Use the Crop tool to remove any unnecessary whitespace or application chrome around the chart. Resize to your target dimensions: 1200×675px for 16:9 presentations, 1200×800px for 3:2 document use, or 1080×1080px for social media. Add a chart title using the Caption tool if the original does not include one. Compress to under 500KB for web and presentation use.
Chart Design Best Practices
- Always label your axes clearly with units of measurement
- Use a legend whenever the chart has multiple data series
- Choose colours that are distinguishable for colour-blind viewers — avoid red/green combinations
- Remove chart junk — gridlines, 3D effects, and decorative elements that do not convey data
- Round numbers for clarity — "47.3%" is less powerful than "nearly half"
