Are there any command-line programs that can convert an SVG to PNG, that run on Mac OS X?

Edit: Dylan B had a good answer with ImageMagick. For reference, to install ImageMagick with SVG support on Mac OS X using MacPorts, do

port install imagemagick +rsvg

Or without installing anything:

qlmanage -t -s 1000 -o . picture.svg 

It will produce picture.svg.png that is 1000 pixels wide.

I have tested it only on OS X 10.6.3.

    Unfortunately this clips images to a square. – Martijn Pieters Jan 30 '11 at 15:13

    Ah, qlmanage -t gives the thumbnail used by Quick Look (in Finder, etc). Clever idea. Unfortunately, these thumbnails can be buggy, especially when there's text involved. – ShreevatsaR Jun 6 '11 at 8:07

    This produces images with the svg file in the 1st quadrant. Doesn't auto crop. Trying to convert files from noun project - wish this worked. – Alex Cook Nov 12 '12 at 20:40

    This solution fails to take transparency into account. The tool rsvg-convert in @ahti's answer worked out before for me. – BenR May 19 '16 at 8:30

    Putting both width and height parameters after the -s option didn't work for me. Still crops it to a square. Very frustrating! – Erik van der Neut Aug 25 '17 at 7:45

I found that for me the best tool for the job is rsvg-convert.

It can be found in brew with brew install librsvg and is used like this:

rsvg-convert -h 32 icon.svg > icon-32.png

(This example creates a 32px high png. The width is determined automatically.

  • This is the only one that worked for me on Mavericks and commons.wikimedia.org/wiki/… – Aron Ahmadia Jun 10 '14 at 1:03
  • Actually this one worked, while ImageMagick's convert issued errors and failed to covert a complex SVG – Brice Apr 27 '15 at 10:03

    With rsvg-convert, the resulting .png had the right dimensions, but the image came out all black instead of the original colors. With qlmanage the image is cropped to a square. Still searching for a solution :-( – Erik van der Neut Aug 25 '17 at 7:47

    @Ahti You're correct! I failed to note the proper package name in your answer. Your instructions work perfectly when followed correctly, and rsvg-convert works like a charm. I'm sorry for the trouble. – Tom Apr 23 at 2:09

ImageMagick is an extremely versatile command-line image editor, which would probably rival Photoshop if it had, you know, a GUI. But who needs those anyways. :P

Something like the following would convert a .svg to .png, after installation:

$ convert picture.svg picture.png

The original .svg isn't deleted.

    When I installed ImageMagick with Fink, I couldn't convert svg to png - there were some errors. It turned out that I needed to install librsvg2-bin as well. – tst May 21 '10 at 12:44
  • If librsvg2-bin isn't installed (like on OS X) this will fail. Couldn't find a way to get that installed on OS X. – John Sheehan Aug 3 '12 at 18:53

    This won't work well if you want to resize the SVG as it generates blurry images. – Behrang Saeedzadeh May 23 '13 at 3:04

    It doesn't convert all SVG files correctly either; at least qlmanage got all the parts of the image. – Johan Feb 21 '14 at 19:50

Inkscape with it's Commandline-Interface produces the best results for me:

Install Inkscape:

brew cask install inkscape

Convert test.svg to output.png with a width of 1024 (keep aspect ratio):

/Applications/Inkscape.app/Contents/MacOS/inkscape --export-type png --export-filename output.png -w 1024 test.svg

OLD ANSWER (doesn't work anymore with latest inkscape):

/Applications/Inkscape.app/Contents/Resources/bin/inkscape --export-png output.png -w 1024 -h 768 input.svg*

  • This is the only method that rendered my hand-written svg correctly – Griffin Jul 31 '14 at 23:45

OK, I found a simple way to do it on the Mac if you have Google Chrome.

In one sentence, it is to see the svg image in a webpage (must be in an html file), right click on image and choose "Copy Image" and paste to the Preview app.

Steps:

  1. Download or have the svg file in your hard drive, say, somefile.svg
  2. Now, in the same folder, just make an html file tmp.html that contains this line: <img src="somefile.svg">
  3. Now, open that html file in Google Chrome
  4. You should see the image. Now just right click on the image and choose "Copy Image"
  5. Go to Mac's Preview App, and choose, "File -> New from Clipboard"
  6. Now File -> Save the file and you have the png file. (or other file types).

This is tested on the current Chrome (version 48.0) on Mac OS X El Capitan.

Update: I am not sure whether it is due to some restriction imposed by Google Chrome. I just try an SVG file using Chrome 58.0, and I get a tiny image from the method above. If you see this case too, you can also use

<img src="somefile.svg" style="height: 82vh; margin-top: 9vh; margin-left: 9vh">

or if you want more margin, use:

<img src="somefile.svg" style="height: 64vh; margin-top: 18vh; margin-left: 18vh">

and you will have an image on screen good enough for you to do a screenshot -- using CmdShift4 or CmdShift3 on the Mac, for example. Make sure you resize your Chrome window to the maximum allowed on the screen first.

    This actually produces the best results for me since it renders exactly the same as the browser. – Jason Haslam Jan 26 '17 at 1:25
  • the resulting image was very poor resolution for me – Michael Sep 22 '17 at 16:02
  • Ingenious :) but for very large SVGs, the resolution of the resulting image is too low, as @Michael mentioned. – waldyrious Oct 23 '18 at 10:24

I have made svgexport using node/npm for this, it is cross-platform and can be as simple as:

If you want to do many at once, you can:

mogrify -format png *.svg

There are options to resize etc on the fly, too..

    I'm not the one who downvoted, but worth noting is that ImageMagick stupidly converts svg to a raster image of arbitrary size before resizing, resulting in blurry output. – Dae Nov 1 '15 at 19:47
  • Installing inkscape first (and getting it on the path) can improve conversion results. – Holly Cummins Nov 26 '19 at 17:28

Try Apache Batik.

java -jar batik-rasterizer.jar FILES

It also supports batch conversion and has many other useful options.

You can also use phantomjs to render the svg. The advantage is that it renders it like a browser would since it's basically a headless WebKit.

Once you download it you need phantomjs (binary) and the rasterizer.js file from the examples folder.

phantomjs examples/rasterize.js Tiger.svg out.png

    For reference, this can be installed with brew cask install phantomjs. In my install, the examples folder was located in the path /usr/local/Caskroom/phantomjs/2.1.1/phantomjs-2.1.1-macosx/examples/. – waldyrious Oct 23 '18 at 10:26

This is what I used:

brew install imagemagick --with-librsvg

Then run the following commands:

find . -type f -name "*.svg" -exec bash -c 'convert $0 $0.png' {} \; rename 's/svg\.png/png/' *

Hope it helps.

Yet another method without installing anything. Not in command line though.

  1. Open the .svg file in Safari.
  2. Press alt-command-i to open the inspector.
  3. Right-click on the <svg> tag, select "Capture Screenshot". (Note that you mustn't zoom in the image.)

P.S. To enlarge the .svg image if it's too small, try opening the .svg file in text editor and append 0 to every number except in the meta-attribute. This can be done by a global regex substitution from (\d+) to $10, where $1 is the placeholder for back reference, for example.

I use this command on my linux. It should work for you as well.

mogrify +antialias -density 2000 -verbose -format png *.svg

I learned that without the "-density" argument, the bitmap would be very pixelized. Change the -density value to match your need.

| improve this answer | |
  • 2
    Even with density, the conversion does not generate an image that is as sharp as a vector image. Try Apache Batik instead. – Behrang Saeedzadeh May 23 '13 at 3:06

ImageMagick's convert command, using some other parameters, is what did it for me. Here's my batch Bash script solution that divides the task across multiple processes to make use of all your cores! Modify as needed.

batchConvertToSVG.sh (takes number of processes as argument):

end=$(( $1 - 1 ))
for i in `seq 0 $end`;
        do
            echo Spawning helper $i of $end
                ./convertToSvgHelper.sh $i $1 &
        done 

convertToSvgHelper.sh:

n=$1
for file in ./*.svg; do
   filename=${file%.svg}
   echo converting file named $filename
   test $n -eq 0 && convert -format png -resize 74 -background transparent -density 600 $file $filename.png
   n=$((n+1))
   n=$((n%$2))
done

You may want to checkout svgexport:

svgexport input.svg output.png 64x
svgexport input.svg output.png 1024:1024

svgexport is a simple command-line tool and npm package that I made for exporting svg to png/jpeg. To install svgexport install npm, then run:

npm install -g svgexport

As commented previously ImageMagick does the trick. I just wanted to add a point for GraphicsMagick, an old fork of ImageMagick that has some improvements (and much less dependency bloat when installed via fink).

You can perform a batch conversion on an entire folder of SVG files to PNG. I used Inkscape command line interface to produce png files with a width of 80px.

find ~/desktop/toconvert '*.svg' -exec /Applications/Inkscape.app/Contents/Resources/bin/inkscape -z -w 80 -e "{}".png "{}" \;

png will be saved with original name *.png

wkhtmltoimage (from project wkhtmltopdf) did this convert well:

I have started to put together a tool to provide a simplified interface to common actions.

You can convert an SVG to a PNG like this:

$ npm install @mountbuild/mouse -g
$ mouse convert input.svg -o output.png

This will create a new PNG for the SVG.

If nothing else check out the source and see how to write your own script to do this in JavaScript.
