LumasWindows C/C++
The engine as a DLL, with the header and both bitnesses.
Native library win-x86 win-x64
Who this is for: C and C++ developers targeting Windows on Intel.
win32/ and win64/ each carry LumasPdf.dll and its import library. Link against the .lib, ship the .dll beside your executable.
The download is public and needs no key. Unlicensed output carries an evaluation watermark and nothing else is restricted.
Is this the right package for you?
Best for
You are writing C or C++ for Windows and want the engine as an ordinary DLL with a header — no wrapper, no marshalling layer, and the same function names the manual documents.
Not the right choice when
You need one binary that also runs on Linux or macOS. The API is identical there, but each platform is its own package, so a cross-platform product needs more than this one.
What is in the download
Generated from the packaging script, not from a description. Each row names the build output the binary came from.
| Platform | Built from | Licence covers it |
|---|---|---|
win-x86 |
win_pair | Yes |
win-x64 |
win_pair | Yes |
Install
unzip windows-cpp.zip
cl /I include your_app.c win64\LumasPdf.libYour first PDF
The smallest complete program: create, write, close.
#include "lumaspdf.h"
int main(void) {
void *pdf = pdfCreatePDF("hello.pdf");
pdfAppend(pdf);
pdfSetFont(pdf, "Helvetica", fsNone, 24.0, 1, cp1252);
pdfWriteFText(pdf, taCenter, "Hello from LumasPDF");
pdfEndPage(pdf);
pdfCloseFile(pdf);
pdfDeletePDF(pdf);
return 0;
}How it deploys
Ship the DLL beside your executable. It has no runtime dependency beyond the C runtime, so there is nothing to install on a customer machine and nothing to register.
Platforms
Two different questions, answered separately, because for one package today they have different answers.
| Platform | Licence covers it | Binary in the download |
|---|---|---|
win-x86 |
Yes | Yes |
win-x64 |
Yes | Yes |
What you can build with it
The same documented API is behind every package. These are the areas most of it is in.

Questions about this package
Do I pay a royalty for every copy I ship?
No. Every edition is royalty-free: you may redistribute the engine inside your own application to as many end users as you like, with no per-copy fee and no runtime licence for them to accept.
Does the licence need to phone home or be activated?
No. Your build verifies the key locally, in your process. There is no activation call, no deactivation, and no server for us to take down — which is why the engine works in an air-gapped network and in a container that scales to zero.
What happens when my maintenance period ends?
Nothing stops working. A key licenses any build released on or before your coverage date, forever, including in production. Maintenance decides which BUILDS the key covers, never when it expires — the engine compares against a build date and never against the clock.
What does the free download do without a key?
Everything. The download is public and unrestricted and needs no key to run; unlicensed output simply carries an evaluation watermark. Register and we send a trial key that removes it, so you can evaluate the real output before you buy.
Can we buy on a purchase order and get a VAT invoice?
Yes. Request a quote and we will price the configuration, invoice against your PO, and show the VAT treatment for your country on the quote itself rather than after checkout.
Try Windows C/C++ before you decide
Public download, no account, no card. Register only when you want the evaluation watermark gone.
