Common Misconceptions: `pdfkit` and HTML to PDF

`pdfkit` is frequently misunderstood for PDF to HTML conversion. It specifically converts HTML and CSS into PDF documents. It is not designed for the reverse process, expecting HTML as input, not PDF.

`pdfkit` is for HTML to PDF, Not Vice-Versa

It is crucial to clarify a prevalent misconception concerning the Python library pdfkit. While its name might suggest versatility, pdfkit is explicitly engineered for a singular, well-defined purpose: converting HTML and CSS content into PDF documents. It serves as a convenient wrapper around the robust command-line tool wkhtmltopdf, which leverages the WebKit rendering engine to transform web pages into high-fidelity PDFs. Therefore, any expectation that pdfkit can perform the reverse operation – converting a PDF file into HTML markup – is fundamentally incorrect. Users frequently encounter errors, like “wkhtmltopdf exited with non-zero code 1,” when attempting to feed a PDF as input, because the underlying mechanism is designed to process HTML files and generate PDF outputs. The from_file method, for instance, unequivocally expects an HTML source file as its input, and a PDF as its resulting output. This clear distinction is vital for developers to avoid fruitless efforts and correctly select appropriate tools when dealing with PDF to HTML conversion tasks in Python. Relying on pdfkit for PDF content extraction will only lead to errors, confirming its dedicated role in HTML to PDF transformation.
