Leadtools version: v14
Platform: .NET 2.0 using C#

All I am doing is simply adding a 10kb image to each PDF page and saving to separate TIFF files

Original PDF file size: 4.3 MB
PDF contains both B/W & color pages - 23 pages total
Below are PDF and JPEG options
PDF Load options
    DisplayDepth = 24
    X/Y Resolutions = 300
JPEG Save options
    QualityFactor = 5

Problem is that, even though I change around resolutions, resultant Tiff files are too big
When PDF resolution is set to 300, Tiff files become 150MB.
Event with 150 or 72, Tiff file sizes become at least 60MB and over.

What would be the best practice (good compression with good quality) to convert each PDF files to TIFF images?
I was expecting result file to become like 5~10MB.

Thank you

You must be saving the TIF files as uncomressed. If you need color, try saving the files as TIF JPEG or TIF LZW. If you want B/W, save the images as TIFF CCITT Group 4.

If you continue to have problems, please post the code snippet of your loading and saving code and the input PDF file you're using.

NOTE: If you are attaching a project or file to the forums...

1.) Zip the file(s) up.

2.) Make sure it is less than 5 MB. If it is larger, please send an email to support@leadtools.com and we'll send you FTP instructions.

3.) Remove ANY AND ALL unlock codes and LEADTOOLS DLLs.

4.) Do not click the preview button, the attachment will not show up when you post it.

If you do not wish to post your file(s) on the forum since they are publically viewable, please send an email to support@leadtools.com and make sure that you include a link to this forum post.
