Analysis based on publicly available information as of April 2026.
Simple migration path
Moving from Google Image Charts to ChartQuery takes minutes, not days. ChartQuery uses a modern JSON API that maps cleanly to the chart types you already use.
Map your chart types
Google's cht=bvg becomes type: 'bar'. Same chart types, cleaner syntax.
Switch to JSON payloads
Replace query-parameter URLs with structured JSON POST requests. Easier to read, debug, and maintain.
Add your API key
Get a free API key and start rendering. No upfront cost, no commitment.
Feature-by-feature comparison
Google Image Charts was designed in a different era. ChartQuery is built for modern development workflows with far more capabilities.

Why migrate to ChartQuery
Google Image Charts was a product of its time. ChartQuery gives you everything it offered, plus a decade of innovation in data visualization.
No more deprecation risk
Google Image Charts has been in deprecation since 2012 and could disappear overnight. ChartQuery is an actively developed product with a clear roadmap and 99.95% uptime SLA.
Modern JSON API
Replace cryptic query parameters (cht=bvg&chd=t:5,5,5) with clean, readable JSON POST requests. Easier to write, debug, and maintain in any language.
28 diagram languages
Google Image Charts had zero diagram support. ChartQuery renders Mermaid, PlantUML, GraphViz, D2, and 24 other languages as PNG or SVG.
AI-powered generation
Describe a chart in plain English and get it rendered automatically. Send raw CSV or JSON data and let the AI figure out the best visualization.
SVG, JPEG & PDF output
Google Image Charts only produced PNG. ChartQuery outputs PNG, SVG, JPEG, and PDF, giving you vector graphics and document-ready formats.
Sub-500ms, EU-hosted
Most endpoints respond in under 500ms. All infrastructure is EU-hosted and GDPR compliant. Continuous monitoring with a public status page.
From deprecated URLs to modern API
Google Image Charts used cryptic query-parameter URLs. ChartQuery uses a clean JSON REST API that works with any modern framework.

Is Google Image Charts still working?+
As of now, Google Image Charts still responds to requests, but it has been officially deprecated since April 2012. Google's deprecation policy means it could be shut down at any time without prior notice. There have been no updates or bug fixes in over a decade.
How do I migrate from Google Image Charts?+
Migration involves switching from query-parameter URLs to ChartQuery's JSON API. The chart types map directly: cht=bvg becomes type: 'bar', cht=lc becomes type: 'line', cht=p becomes type: 'pie'. Replace the data format (chd=t:...) with a standard JSON datasets array. Our documentation includes a complete migration guide.
Is ChartQuery compatible with Google Image Charts URLs?+
ChartQuery uses a modern JSON API, not the legacy query-parameter format. However, the chart types and data concepts are the same. Migration typically involves reformatting your chart configuration from URL parameters to JSON, which takes minutes per chart.
What about QuickChart as a Google Image Charts replacement?+
QuickChart offers partial Google Image Charts URL compatibility, covering charts, QR codes, and GraphViz. ChartQuery goes further with 28 diagram languages, AI generation, barcodes, labels, SVG/PDF output, and EU-hosted infrastructure. See our QuickChart comparison for details.
Does ChartQuery have a free tier?+
Yes. ChartQuery offers a free tier with 60 requests per hour per IP, no API key required. All five APIs (charts, diagrams, AI generation, barcodes, labels) are available. Rendered images include a watermark on the free tier.
What if I need the exact Google Image Charts URL format?+
If you have a large codebase using the cht/chd/chs parameter format and cannot refactor, QuickChart offers partial URL compatibility. However, we recommend migrating to ChartQuery's JSON API for better reliability, more features, and long-term support. The JSON format is also easier to read, test, and maintain.
