DESCRIPTION

This sample gets files specified by the user from the 
selected folder and batch processes them and saves them 
as SVGs in the user desired destination with the same 
file name.

Based on Adobe's "Save as PDFs" sample script, intended for Illustrator CS6

@seltzered Hey man, thanks a ton for this. Just made my life a whole lot easier.

This is awesome! Thanks!

this isn't working in Adobe Illustrator CC 2014

This saved me a ton of time. Thanks

It doesn't work in subfolders.

I tried " * / * .ai" as file name mask, but no result.

To get this script working with CC2015, replace line 46 with this (and don't input anything when prompted, just hit enter):
fileType = prompt( 'Select type of Illustrator files to you want to process. Eg: .ai', '.ai' );

This was just great. It saved me a LOT of time. Thank you!

Thank you! It saved me a lot of time and nerves.

Any chance this works for cc 2018?

@Sqwear I can confirm this works, good stuff!

Extended script with options for optimizing svg

function getSVGOptions() { var svgSaveOpts = new ExportOptionsSVG(); svgSaveOpts.embedRasterImages = false; svgSaveOpts.cssProperties = SVGCSSPropertyLocation.PRESENTATIONATTRIBUTES; svgSaveOpts.coordinatePrecision = 3; svgSaveOpts.fontType = SVGFontType.SVGFONT; svgSaveOpts.documentEncoding = SVGDocumentEncoding.UTF8; svgSaveOpts.fontSubsetting = SVGFontSubsetting.None; return svgSaveOpts; }

Tested with some Illustrator files, which are a bit older version, I'm getting a "Convert to Artboards" pop-up for every file.
Is it possible to remove it? Or to only choose one time for all the files?
The options that I'm seeing are "Create artboards for: 1) Legacy Artboards 2) Crop area(s) 3) Artwork Bounding Box.
Would be great to only have Crop area(s) checked... All though I can surely understand if you don't have time for this. :-D

Hey very thanks!!!

Thanks a lot.
