How can I convert Plotly graph to a PNG image

November 10, 2022

I have this Plotly graph, and I’m trying to save it as a png or JPEG file

import plotly.graph_objects as go
import numpy as np
np.random.seed(1)

N = 100
x = np.random.rand(N)
y = np.random.rand(N)
colors = np.random.rand(N)
sz = np.random.rand(N) * 30

fig = go.Figure()
fig.add_trace(go.Scatter(
    x=x,
    y=y,
    mode="markers",
    marker=go.scatter.Marker(
        size=sz,
        color=colors,
        opacity=0.6,
        colorscale="Viridis"
    )
))

fig.show()

I want to save this fig as an image

>Solution :

You can do that by using the .write_image() function; by this function, you will be able to write your image as PNG/JPEG/WEBP or as a pdf, even and many other type

as png: fig.write_image("fig1.png")

as jpeg : fig.write_image("images/fig1.jpeg")

The plotly.io.write_image function is used to write an image to a file or file-like python object. You can also use the .write_image graph object figure method.
