PDF to HWP Converter

In Korea, Hangul is still the usual word processor in public offices, schools and many companies, so their templates, forms and internal workflows are built around .hwp files. When a ministry, a district office, a university department or a school publishes a form only as a PDF, the instruction is often to fill it in and send it back as HWP. Typing over a PDF is awkward, and retyping a two-page form by hand takes far longer than converting it.

The same need appears in the other direction of business. A partner abroad sends a contract draft or a report as PDF, and a Korean colleague wants to edit it with the tools the team already uses. Converting the PDF to HWP gives them a document that fits straight into their usual review, comment and approval process.

If what you need is the opposite, reading a Korean document without Hangul, use HWP to PDF instead.

The two formats were built for different jobs. A PDF records where every character, line and image sits on the page, which is why it prints the same everywhere and why it is hard to edit. An HWP document stores paragraphs, styles, tables and page settings, the structure a word processor needs to let you change the text and have the layout follow.

HWP is Hancom's own format rather than an international standard, but it is documented: Hancom published the HWP binary format on June 29, 2010, which is what allows tools outside Hangul to write files that Hangul opens.

The hardest step is the third one. A PDF has no idea where a paragraph ends; it only knows that some characters sit on one line and more sit on the next. The converter looks at spacing, alignment and font size to decide what belongs together, and turns grids of lines into real table cells. Official Korean forms are mostly tables, so this is what decides whether you can type into the boxes afterwards.

Keep formatting is preset because forms and letters depend on their layout. If the HWP gets cluttered with text boxes, switch to Simple under Advanced settings: you lose some positioning, but the text flows as ordinary paragraphs that are easier to edit.

Many PDFs sent around Korean offices are scans of printed forms with stamps and handwriting. OCR is on by default, so the printed text on those pages becomes editable. Handwriting, seals and signatures are kept as images, which is usually right: a seal should not turn into text. Proofread names, resident registration numbers, dates and amounts before you submit anything, since OCR can confuse similar characters.

Fonts are the second thing to check. The HWP refers to the fonts the PDF used; if your copy of Hangul does not have them, it substitutes a similar Korean font, and line breaks can move a little. Open the file, look through every page, and fix any table row that has grown taller than the original.

When the document is ready, Hangul saves it as HWP or exports it again as PDF. To pull only the words out of a PDF for a message or another program, PDF to Text is quicker, and the Document Converter page covers the other office formats.
