It was strangely difficult to find freeware programs/services that support WEBP conversion, but here’s a list of desktop and online converters that do (as of Nov 2013 others may have followed suite as you read this). List of free converters that support WEBP as source: It also adds WEBP thumbnail preview support in Windows Explorer, but does not really help much if you want to convert from WEBP to do that you can use one of the FREE converters/image viewers below. Windows Photo Viewer, MS Office 2010, and FastPictureViewer). Interestingly, a WEBP codec is available for Windows, which provides WEBP support for a number of common Windows applications (e.g. If you have come across WEBP and, like me, found that your image conversion and editing programs will not recognize or convert it to other formats, this post will suggest a number of ways to do it. While Google’s introduced the WEBP image format in 2010, it seems to have taken a while to become more widely used on the internet. For example, it supports both lossy and lossless compression, and can result in a file size saving of 45% over PNG (preserving transparency) and 28% over the same PNG’s that are re-compressed with compression tools (source: Wikipedia). If you can convert a pdf with imagemagick, you already have gs installed.Why WEBP? The format introduces improvements on many fronts, according to Google. The convert command of imagemagick does use the gs command internally.

The last (unnamed parameter is the input file.).

Would result in two files named item-001.png and item-002.png. Tells gs to include a counter for multiple files.

-sOutputFile defines the name(s) of the output file.

Large white margin and you don't want this margin on your output this -dUseCropBox tell gs to use a CropBox if defined.If you have a PDF with 300dpi and specify -r600 your images will be upscaled. Output sizes use -r70 or if you input pdf has a high resoultion use -r300 sets the scan resolution to 300dpi.Use the -dJPEGQ=N (N is an integer from 0 to 100, default 75) Jpegs use -sDEVICE=jpeg to produce color JPEG files. sDEVICE tells gs what output format to produce.Important if you want to run the command in a bash script. More or less it will not ask any questions. dBatch and dNOPAUSE just tell gs to run in batch mode, which means.gs -dBATCH -dNOPAUSE -sDEVICE=pnggray -r300 -dUseCropBox -sOutputFile=item-%03d.png examples.pdf This is an old question, but as a GhostScript answer is missing and there is no hint for multipage PDF export yet I think adding another variant is ok.
