Readable C++ source documents
Convert C++ source code into a printable PDF
KissPDF converts uploaded C++ (CPP) files or pasted source into polished, readable PDF pages—not screenshots or one tall image. Preprocessor directives, templates, namespaces, classes, comments, strings, and other C++ syntax remain easy to scan while the text stays selectable and searchable.
The page preview and downloaded file are generated from the same document snapshot. Choose the code size, light or dark code theme, line numbers, title, paper size, margins, and page numbers before exporting. Your source is formatted locally and is never compiled or executed.
Three steps
How to convert C++ or .cpp code to PDF
Upload or paste C++ code
Open a .cpp, .cc, .cxx, .hpp, .hh, .hxx, or .h file, or replace the sample with a class, algorithm, header, assignment, or review snippet. C++ highlighting is selected automatically.
Set up the document
Use the right sidebar to adjust the code size, light or dark code theme, line numbers, title, paper format, margins, and page numbering.
Preview and download
Inspect the actual paginated PDF, zoom or move around the preview, then download the same layout directly without using a system print dialog.
Made for C++ source
When a C++ code PDF is useful
A C++ project normally belongs in version control, but a stable paged copy is useful when code must be reviewed, submitted, printed, or attached to another document without requiring an IDE or build toolchain.
Assignments and algorithm handouts
Submit data-structure exercises, competitive-programming solutions, lab work, or teaching examples with stable line numbers reviewers can cite.
Source and design reviews
Share a focused class, implementation file, template, API example, or header when a reviewer needs readable source rather than an entire repository.
Engineering report appendices
Attach embedded, systems, simulation, graphics, or performance-critical C++ excerpts to technical reports while keeping the code searchable.
C++-aware formatting
Keep modern C++ readable on the page
C++ source mixes nested scopes, templates, macros, operators, and long type names. Monospaced formatting preserves that structure, while automatic pagination turns long files into conventional PDF pages.
C++ syntax highlighting
Keywords, preprocessor directives, types, namespaces, templates, strings, numbers, comments, and function or class declarations receive distinct source-code styling.
Indentation and punctuation
Spaces, braces, scope operators, pointers, references, and aligned comments remain monospaced instead of being reflowed like prose.
Source and header files
Open common C++ source and header extensions including .cpp, .cc, .cxx, .hpp, .hh, .hxx, and .h, or paste a smaller excerpt directly.
Formatting without a compiler
The converter does not invoke GCC, Clang, MSVC, CMake, or your program. Includes are not resolved and the code is never built or executed.
Common questions
C++ to PDF FAQ
How do I convert a .cpp file to PDF?
Click Open file and choose a local .cpp file, or paste the source into the editor. Adjust the page options, inspect the exact preview, and download the PDF. The source file is read locally in your browser.
Which C++ file extensions can I open?
The converter recognizes .cpp, .cc, and .cxx source files plus .hpp, .hh, .hxx, and .h headers. All of them use the C++ language mode on this page.
Does the converter compile or run my C++ code?
No. It formats source text only. It does not call a compiler, resolve #include directives, link libraries, run binaries, or inspect a local build environment.
Are templates, macros, namespaces, pointers, and references preserved?
Yes. The original characters, line breaks, and indentation remain in the document, and the C++ syntax mode highlights common language tokens and preprocessor directives.
Can I convert an entire multi-file C++ project at once?
This editor works with one source document at a time. Open an individual source or header file, or combine the excerpts you need in the editor before downloading. It does not package a repository into one PDF automatically.
Is C++ to PDF different from C to PDF?
Yes. This page starts in C++ mode and is intended for C++ constructs such as classes, templates, namespaces, references, and the standard library. You can still select C from the language control when formatting C source.
Can I remove the document title or line numbers?
Yes. The title, line numbers, and page numbers are separate settings. The exact PDF preview updates before you download the file.
Will long C++ files break across normal PDF pages?
Yes. Long source continues across paginated A4 or Letter pages and remains selectable and searchable instead of being flattened into a tall image.
How do I save C++ code from Visual Studio as a PDF?
Open the .cpp or header file from your Visual Studio project with this converter, or copy the source from the editor and paste it here. You can then add line numbers, preview the pages, and download a PDF without relying on the Visual Studio print dialog. The project is not compiled or modified.
