How to Create Graph Images at imgresizr.com
Generate your graph in Excel, Google Sheets, Python matplotlib, or R ggplot, then export as a PNG or take a screenshot. Upload to imgresizr.com and use the Crop tool to remove any unnecessary white margins or application chrome. Use the Enhance tool to sharpen the graph lines and data points, and boost contrast so the data visualisation is crisp. Resize using the Resize tool to your target dimensions. For academic use, maintain the aspect ratio to avoid distorting the data. Add a descriptive figure caption below the graph using the Caption tool if preparing for a document. Compress to under 500KB for web or presentation embedding.
Graph Image Quality Tips
- Export graphs at 300dpi from your graphing software for print-ready quality
- Use a white or transparent background for maximum versatility across documents
- Ensure all axis labels and legend text are at minimum 10–12pt for readability
- Line graphs should have lines thick enough (2–3pt) to be visible when printed small
- Always include your data source as a footnote for academic and professional credibility
