# png2svg

This is a simple tool invoked from the command line which converts a png into an svg that uses jpeg compression.  This can significantly reduce image sizes for use on the web.

## Installation

Download and unzip the built version, then invoke from the command line or run as a node-webkit app.

#### Downloads

   * Windows: [32bit](https://github.com/arenanet/png2svg/releases/download/0.1.0/png2svg-win32.zip) - [64bit](https://github.com/arenanet/png2svg/releases/download/0.1.0/png2svg-win64.zip)

   * OSX(not tested/supported): [32bit](https://github.com/arenanet/png2svg/releases/download/0.1.0/png2svg-osx32.zip) - [64bit](https://github.com/arenanet/png2svg/releases/download/0.1.0/png2svg-osx64.zip)

   * Linux(not tested/supported): [32bit](https://github.com/arenanet/png2svg/releases/download/0.1.0/png2svg-linux32.tar.gz) - [64bit](https://github.com/arenanet/png2svg/releases/download/0.1.0/png2svg-linux64.tar.gz)

## Usage

```bat

d:\png2svg\png2svg.exe -f d:/image.png -q 0.7

```

#### Options

    -f, --file          Absolute path to png file to convert into an svg

    -q, --quality       Image quality, 0-1 (default 0.83)

    -s, --show          Keep the node-webkit window open when finished

    -p, --webp          Use webp instead of jpeg for the embedded dataUrl

#### Notes/tips

   * You must provide an absolute file path

   * The generated svg file will be written to the same directory with the same name as the png, but with the .svg extension

   * Use -s to show info/errors (I'd prefer to have all the interaction via command line, but node-webkit doesn't have support for this)

   * Make sure your server gzips svgs!
