Is there any way to save a plot (from Plots but I’m open to something else) as a jpeg? I’m creating several hundred simple line graphs as pngs, but I’d like to speed loading on the web by jusing a jpeg.None of the Julia packages seem to do this.

With the PythonPlot backend (Matplotlib) you should be able to do `savefig("foo.jpg")` to save as JPEG. (Or using PyPlot or PythonPlot directly, of course.) You can also save as PNG and then batch-convert to JPEG with some tool, e.g. ImageMagick.

That being said, for simple line graphs it’s probably more efficient to save as PDF or [gzip-compressed SVG](https://en.wikipedia.org/wiki/SVG#Compression), or even uncompressed SVG. e.g. if I do `plot(rand(100))` and do `savefig` in various formats, I get 34kB for JPEG (with the default compression settings), 54kB for PNG, 14kB for SVG (uncompressed), 7kB for PDF, and 4kB for `.svgz` (gzip-compressed).

(Moreover, for line graphs PDF and SVG are effectively “infinite resolution”, i.e. you can zoom them arbitrarily.)

PS. Plots does not currently support `.svgz` for most backends ([[FR] savefig("foo.svgz") (gzip-compressed SVG) · Issue #4916 · JuliaPlots/Plots.jl · GitHub](https://github.com/JuliaPlots/Plots.jl/issues/4916)) though it should work for Matplotlib / PythonPlot / PyPlot. But you can always `gzip` the `.svg` files after they are created. Or you can do it directly via the GZip.jl package:

```julia
using Plots, GZip
p = plot(...)
gzopen(io -> show(io, "image/svg+xml", p), "bar.svgz", "w") # save as bar.svgz

```
