How to create large PDF files (10MB, 50MB, 100MB, 200MB, 500MB, 1GB, etc.) for testing purposes?
I tried this for ((i=1; i<=10; i++)); do convert 100MB.pdf 10MB.pdf 100MB.pdf; done to create 100MB file but very quickly run out of RAM.
Any ideas?
Answer
The most simple tool: use pdftk (or pdftk.exe, if you are on Windows):
pdftk 10_MB.pdf 100_MB.pdf cat output 110_MB.pdf
This will be a valid PDF. Download pdftk here.
Update: if you want really large (and valid!), non-optimized PDFs, use this command:
pdftk 100MB.pdf 100MB.pdf 100MB.pdf 100MB.pdf 100MB.pdf cat output 500_MB.pdf
or even (if you are on Linux, Unix or Mac OS X):
pdftk $(for i in $(seq 1 100); do echo -n "100MB.pdf "; done) cat output 10_GB.pdf
