Two Pilots forum / Converters / Filesize of image in PDF is bigger than origional
Author Message
# Posted: 12 Oct 2007 03:54

Hi Two-Pilots support,

It seems that colored images result in a .PDF file which is 2.5 times bigger than the origional images.

We create a PDF page with the same width and height of the dimensions of the .tif file. The image is added with the origional width and height, and compression set to Flate.

In version 2.4, a colored .tif image of 254kb results in a PDF of 2,405kb
in verison 3.6, the same colored .tif of 254kb results in a PDF of 847kb
Without the colored.tif image, the document is only 20kb.

jpeg files also grow in size, even with compression set to jpeg or flate.

Tif images with a color dept of 1 bit stay close to their origional file size.

Is there a way to preserve the origional compression of the source image? We convert milions of scans of .tif files to PDF files, and for both storage and network performance the size overhead should be minimal.

Kind regards,

Thank you Stanislav for your response,
I've just filled in the support form and attached a colored .tif, with reference to this forum topic.
