Hi Sebastian,

like tfrost said already:
The "Free" is what you need ;-)

Here's a "Hello World" for the first steps:
http://www.quickpdflibrary.com/tutorials/delphi/hello-world.php
After create and unlock you have to insert your loadfromfile and the very last thing should be always a free.

If there are still memory lacks.
You can stop after a bunch of pages...
Keep the actual page number in mind...
Doing the Free...
Start with a new Create/Unlock/LoadFromFile...
Begin again with the same file but the last page number...

Cheers and welcome here,
Ingo

BTW:
The starting point for help is here:

Do you create PDFLibrary at the start of each conversion, and Free it afterwards?  If not, that is an obvious thing to try first, and is the pattern I have always used. There may be no huge 'memory leak' in the library, but what you describe may still result from fragmentation if some of the fields of the library object remain in use throughout.]]> Wed, 11 Oct 2017 11:31:25 +0000 http://www.quickpdf.org/forum/outofmemoryerror-while-converting-pdf_topic3513_post13984.html#13984 <![CDATA[OutOfMemoryError while converting PDF : Hello,I have a big list of PDF...]]> http://www.quickpdf.org/forum/outofmemoryerror-while-converting-pdf_topic3513_post13983.html#13983 Author: Seb_Stati

Hello,

I have a big list of PDF files to convert into .jpg files.

But at the end of a certain number of conversions, it doesnt work anymore, and I have only OutOfMemory Errors.

This is how I convert my files : 

PDFLibrary->LoadFromFile(filename.c_str(), L"");
nbPages = PDFLibrary->PageCount();
PDFLibrary->RenderDocumentToFile(300, 1, nbPages, 1, cible.c_str());

Am I missing something ? Any way to clear memory ?

Thanks
