About CodeToPDF

CodeToPDF is a collection of free online developer utilities, with source-code-to-PDF conversion as its flagship tool. The PDF converter accepts source files in 50+ languages, including JavaScript, Python, Java, Go, and Rust, and produces syntax-highlighted PDFs with a choice of theme, font, and page size; it supports drag-and-drop of multiple files. The site also offers Markdown-to-PDF and HTML-to-PDF conversion.

Beyond PDF generation, the site provides formatters and validators for JSON, SQL, HTML, CSS, XML, and YAML, a JSON diff/compare tool, Base64 encoding and decoding, a JWT decoder, a UUID generator, a QR code generator, a regex tester, a Unix timestamp converter, and a live Markdown preview. Most tools run client-side in the browser; for the server-side PDF conversion tools, uploaded files are deleted after processing.

The tools do not require account creation or signup and are offered without usage limits or paywalls. The site targets software engineers, DevOps engineers, security researchers, and other technical users who need quick utilities for tasks like formatting data, decoding tokens, or preparing code for review or documentation.
