Turn any chart into a PNG image

A charting library draws in a browser, but most places you need a chart — an email, a PDF report, a README.md, a Notion page, a Slack message — have no browser. To get a chart there you need an image, not a canvas. ChartBytes converts chart data to a PNG image server-side from a single URL.

The URL

Point an <img> or Markdown image at a chart URL and the PNG renders automatically. 
<img src="https://chartbytes.meridian-digital.pro/chart?t=bar&d=12,19,8,24&labels=Q1,Q2,Q3,Q4&title=Sales" alt="Sales chart">

PNG vs SVG

PNG renders identically everywhere and needs no renderer — the safe default for email and PDF. SVG is crisp, small and scales, but some clients block it; use it for web pages and documentation.

What you can chart

Bar, horizontal bar, stacked bar, line, area, scatter, pie and donut — each as a PNG (or SVG), with labels, titles and multiple series.

Free — then Pro

The free tier gives 500 chart renders a month, no watermark, no account. Pro is a one-time $9 for dark and brand themes, 25,000 renders/month and immutable caching.
