How do I convert C code to PDF?

Paste your C source, choose C, then click PDF. Syntax colors, line numbers, and layout settings are included.

Are preprocessor directives highlighted?

Yes. Includes, defines, conditional compilation, types, strings, and comments receive distinct syntax colors.

Does it preserve pointer and indentation formatting?

Yes. Codeprint preserves whitespace and punctuation exactly as entered, including pointer declarations and nested blocks.

Is my C source uploaded?

No. Highlighting and PDF generation run in your browser, so source code stays on your device.

Turn C code into a PDF worth printing.

Keep C syntax colors, line numbers, and the layout you choose. Preview every page and export the PDF without uploading your code.

C Syntax Highlighting

Preprocessor directives, types, pointers, constants, and comments remain visually distinct.

PDF Export

Generate a selectable PDF that keeps syntax colors and line numbers intact.

Layout Options

Use landscape for long declarations or multiple columns for compact source files.

Line Numbers

Reference exact statements during code review, debugging, or classroom walkthroughs.

When you’d print C

Systems Reviews

Trace pointer ownership, memory allocation, and error paths away from the screen.

Embedded Work

Print firmware routines and annotate timing, register, and hardware assumptions.

Teaching

Create readable handouts for data structures, algorithms, and operating-systems courses.

Security Audits

Mark unsafe boundaries and input-validation paths on a stable paper reference.

How it works

Step 1

Paste Your Code

Paste your C code into the editor or type directly. The language is auto-detected from the file extension.

Step 2

Customize Settings

Adjust font size, line numbers, columns, page orientation, and page size to match your needs.

Step 3

Print or Export PDF

Click Print to send to your printer, or PDF to download a formatted document with syntax highlighting preserved.

Why print C?

C source is easier to review when its structure survives the move from editor to page. Preprocessor directives, types, pointers, constants, and comments remain visually distinct. Codeprint keeps indentation and line breaks intact, then applies a restrained syntax palette so keywords, strings, comments, and identifiers remain distinguishable in print.

A paper review creates a different reading rhythm from an IDE. You can see more of the file at once, mark a questionable branch, compare related expressions, and refer back to a precise line without opening the same toolchain. Reference exact statements during code review, debugging, or classroom walkthroughs.

Generate a selectable PDF that keeps syntax colors and line numbers intact. Page size, orientation, columns, and type size remain under your control, which matters when the source contains long expressions or dense blocks. It is a practical fit for systems reviews, embedded work, and technical documentation. Your source stays in your browser throughout the process.
