PDF conversion problem

Irishrossoblu

I am trying to convert a JPG file into a PDF file. I am using the Primopdf converter, but the PDF file come out quite pixelated, both on text and images. I have tried to change the scaling but it doesnt solve the problem. Does anyone have any ideas how to get a clean conversion? Any help is much appreciated.

Thanks

We use CutePDF here. Just print the Jpg to a PDF file. Don't know if you'll have the same problem or not but it's worth a try.

Imagemagick may do it for you.

Also as suggested a PDF Printer may be good, Try PDFCreator, load image in paint or whatever you like, print, select PDFCreator printer driver, and then you have a PDF file as good as what would have been printed on paper.

This sample is extracted from the imagemagick online documentation.

Postscript/PDF Output Options
The following settings are known to effect the output of Postscript, Encapsulated Postscript, and PDF image formats: "-page", "-gravity", "-compress", "-density",

By default no compression is used on PDF image output, so PDF files can often be a lot bigger than nessary. The following table equated the IM compression modes with the resultings Postscript compression mode used.

PS/PDF Compression Meanings
Compression image '/Filter [ ... ]' setting
"-compress none" '/ASCII85Decode'
"-compress zip" '/FlateDecode'
"-compress jpeg" '/DCTDecode'
"-compress lzw" '/LZWDecode'
"-alpha off -monochrome -compress fax" '/CCITTFaxDecode'
"+compress"
"-compress rle"
any thing else '/RunLengthDecode'

Recommended compressions for PDF is Zip (Deflate Compression) or Group4 (Fax) compression.

Thanks logger. The pdfcreator did the business. The Primopdf converter was the problem. Thanks for all the help.
