View and edit PDF, Hangul and Word documents
on your own computer, for free.

Papy is a source-available document app that opens and edits PDF, HWP, HWPX, DOCX and DOC files. Switch between view and edit mode in one step, then save, save as or convert formats, all offline. No sign-up, no ads, no uploads.

v0.4.1 is out with a new app icon. Since v0.4.0, the Hangul engine is updated and Hangul ↔ Word conversion keeps layout more faithfully. Word files with many footnotes and Hangul files with huge tables open much faster. When you save to another format, Papy tells you up front that line breaks and page counts may differ. Get it on the download page.

Korean documents first

Documents and formats

Can I open HWP files without Hancom Office?

Yes. Papy opens HWP (5.x) and HWPX without Hancom Office, and you can edit the text and formatting and save. Tables, images and headers are edited with advanced editing.

Does it work with Word (DOCX, DOC) files?
  • DOCX: open, edit, and save as DOCX, or convert to HWP, HWPX or PDF.
  • DOC (97–2003): open and edit, then save as DOCX, HWP, HWPX or PDF.
  • Images, shapes, grouped shapes, charts, headers, footers, footnotes and numbered lists are carried over.

Papy tells you when a file has elements it cannot carry over yet, such as OLE objects or floating shapes in .doc files.

Does the layout stay the same between Hangul and Word?

The content is carried over, but Hangul and Word break lines and pages by different rules, so line breaks and page counts may differ slightly. Papy tells you before you save to another format and when you open a Word file. Keep the original of important documents.

Can I export to PDF?

Yes. HWP, HWPX, DOCX and DOC documents export to PDF. PDFs open for highlighting, notes, pen, fixing text, and rotating or deleting pages.

When will PowerPoint and Excel files work?

After the three document families (Hangul, Word, PDF) are stable, PPT and PPTX come next, then XLS and XLSX.

Privacy and security

Are my documents sent over the internet?

No. Documents are processed only on your computer. The app goes online only for clearly stated purposes, such as checking for a new version (if that is added). See the privacy policy for details.

I see a security warning when installing.

Papy is not code-signed yet, so Windows and macOS warn on first launch. Files from the official download page are safe to open. See installation for the steps on each system.

Install and devices

Which operating systems are supported?

Windows, macOS (Apple Silicon and Intel) and Linux (.deb, .rpm, AppImage). The download page shows the file for your system first.

How do I get a new version?

Download the new version and install it the same way; it replaces the old one. There is no automatic update yet.

Can I use it on my phone?

Only desktop apps are released for now. Android and iOS apps using the same engine are in preparation.
