8-2 Limit Size on Read / Write

The maximum read/write PDF file size is 2GB. The specific restrictions are as follows.

• The file size of PDF files that can be loaded as input files is up to 2GB. If the PDF file exceeds 2GB, an error will occur when loading.
• The maximum file size of PDF files saved using Antenna House PDF API is 2GB. If it exceeds 2GB (*2), an error will occur when saving.

(*2)
The upper limit of the output file size here is determined by whether the output PDF resulting from PDF processing and editing using Antenna House PDF API exceeds 2GB.
This specific example is the case when merging PDF files. Merging PDF files using Antenna House PDF API is not a process of physically merging PDF files.
Therefore, if the merged output PDF exceeds 2GB, an error may occur even if the total PDF file size before merging is less than 2GB.

For specific PDF file merging operations, see "12-4 -mergeFiles: Merging PDF files" in this manual.
