Convert PDF to clean SVG? – Stack Overflow

I'm attempting to convert a PDF to SVG. However, the one I am using currently maps a path for every letter in every piece of text, meaning if I change the text in it's source file, it looks ugly. I was wondering what the cleanest PDF to SVG converter is, hopefully one that doesn't have a path for it's text areas that simply don't need one. As we know, PDF and SVG are fairly similar, so I assume there's some good converters out there. http://en.wikipedia.org/wiki/Wikipedia:Graphic_Lab/Resources/PDF_conversion_to_SVG#Conversion_with_Inkscape I am currently using PDFBox which has good support for graphic output. There is good support for extracting the vector strokes and also for managing fonts. There are some good tools for trying it out (e.g. PDFReader will display as Java Graphics2D). You can intercept the graphics tool with an SVG tool like Batik (I do this and it gives good capture). There is no simple way to convert all PDF to SVG - it depends on the strategy and tools used to create the PDFs. Some text is converted to vectors and cannot be easily reconstructed - you have to install vector fonts and look them up. Later packages will (hopefully) convert the characters to running text and the paths to higher-level graphics objects UPDATE: We can now re-create running text from the SVG characters. We've also converted diagrams to domain-specific XML (e.g. chemical spectra). See https://bitbucket.org/petermr/svg2xml-dev. It's still in Alpha, but is moving at a useful speed. Anyone can join in! UPDATE. (@Tim Kelty) We are continuing to work on PDF2SVG and also downstream tools that do (limited) Java OCR and creation of higher-level graphics primitives (arrows, boxes, etc.) See https://bitbucket.org/petermr/imageanalysis https://bitbucket.org/petermr/diagramanalyzer https://bitbucket.org/petermr/norma and https://bitbucket.org/petermr/ami-core . This is a funded project to capture 100 million facts from the scientific literature (contentmine.org) much of which is PDF. It offers a tool, pdf2png, which once installed does exactly the job in command line. I've tested it with irreproachable results so far, including with bitmaps. EDIT : My mistake, this tool also converts letters to paths, so it does not address the initial question. However it does a good job anyway, and can be useful to anyone who does not intend to modify the code in the svg file, so I'll leave the post. If DVI to SVG is an option, you can also use dvisvgm to convert a DVI file to an SVG file. This works perfectly for instance for LaTeX formulas (with option --no-fonts): There is also pdf2svg which uses poppler and Cairo to convert a pdf into SVG. When I tried this, the SVG was perfectly rendered in inkscape. Here is the process that I ended up using. The main tool I used was Inkscape which was able to convert text alright. Using Adobe Acrobat Pro Actions (formerly Batch Processing) create a custom action to separate PDF pages into separate files. Alternatively you may be able to split up PDFs with GhostScript Using Windows Cmd created batch file to loop through all PDF files in a folder and convert them to SVG I realize it is not best practice to manually brute force edit SVG or XML tags or attributes due to potential variations and should use an XML parser instead. However I had a simple issue where the stroke width on one drawing was very small, and on another the font family was being incorrectly identified, so I basically modified the previous Windows Cmd batch script to do a simple find and replace. The only changes were to the search string definitions and changing to call a PowerShell command. The PowerShell command will perform a find and replace and save the modified file with an added suffix. I did find some other references that could be better used to parse or modify the resultant SVG files if some other minor cleanup is needed to be performed. powershell -Command '(Get-Content '%~n1.%_work_x1%') | ForEach-Object {$_ -replace 'stroke-width:0.06', 'stroke-width:1'} | ForEach-Object {$_ -replace 'font-family:Times Roman','font-family:Times New Roman'} | Set-Content '%~n1%_work_s2%.%_work_x2%'' Source.
