Convert an HWP file to PDF on Android

Without an app, and the catch

HWP and HWPX are Korean word-processor formats, and Android phones usually have no app that opens them. If the phone cannot open the file, it cannot print it to PDF either, so the app-free options are all off the phone:

Save as PDF in HWP Viewer SugarDoc

  1. Open the document — tap the HWP or HWPX file in KakaoTalk, email or your file manager and choose HWP Viewer from Open with or Share, or pick it with Find in my files inside the app.
  2. ⋮ → Save as PDF — tap ⋮ at the top right of the document and choose Save as PDF.
    With an HWPX document open, the More options menu lists Save as PDF and Print as separate items, shown here in the Korean interface.
    Document content is blurred.
  3. Check the page notice — if the document is longer than the limit, the app tells you how many pages will be saved first. Tap Save to go on or Cancel to stop without making a file.
    For a 47-page HWP document the app says only the first 15 pages will be saved as a PDF, with Cancel and Save buttons, in Korean.
  4. Pick where to save — Android's save screen opens with the document's name plus .pdf filled in. Choose a folder and tap Save.
  5. Done — the message "Saved as a PDF." appears. The HWP or HWPX file you received is not changed.
    After saving, a message at the bottom of the screen confirms the PDF was saved, in Korean.

Checked on a Galaxy S21 (Android 15) with the SugarDoc 1.2.0 release build on October 18, 2026: a 47-page HWP document showed the notice and produced a 15-page PDF, and a 3-page HWPX document was saved with all 3 pages.

Tap Print in the ⋮ menu to open Android's print screen (on versions before 1.2.0 the item is called Print or save as PDF). Under Select printer, choose the save-as-PDF option (its name varies by phone) to keep the result as a PDF file. Use this if Save as PDF fails; the same page limit applies.

"In Android 4.4 (API level 19) and higher, the framework provides services for printing images and documents directly from Android applications."

Which way to use

MethodPhone onlyUploadLengthUse it when
SugarDoc Save as PDFYesNoneFirst 15 pages (6 on low-memory phones)You need a short notice or letter as a PDF right now
SugarDoc Print → PDFYesNoneSame as aboveSave as PDF failed, or you are on a version before 1.2.0 (there the item is ‘Print or save as PDF’)
Ask the senderYes (you wait)NoneNo limitThe layout must match, or it is longer than 15 pages
Desktop HWP programNoNoneDepends on the programYou need to edit a long document first
Web converterYesTo their serverVaries by siteThe document has no personal information

Verdict: for a document of 15 pages or fewer that you need as a PDF now, Save as PDF in the app is the quickest. For longer documents or forms where layout matters, get a PDF from the sender or make it on a computer.

Limits and what to do when it fails

About the HWP format

HWP is the native format of the Hancom word processor widely used in Korea. Its specification is public, which is why other apps can read it. Hancom says (in Korean) that it published the HWP binary format and the HWPML markup language on June 29, 2010: "한컴은 2010년 6월 29일에 자사의 바이너리 포맷인 HWP와 마크업 언어인 HWPML을 공개하였습니다."

FAQ

Does saving as PDF cost anything?

No. Save as PDF and Print need no payment, and the app has no ads.

Is my document uploaded anywhere?

No. SugarDoc does not send documents to a server; the PDF is made on your phone. See the HWP Viewer SugarDoc privacy policy.

Where is the saved PDF?

In the folder you picked on the save screen. The folder shown first can differ by phone, so check its name before you tap Save. Afterwards you can find the PDF in your phone's Files app.

Can I convert a document longer than 15 pages in full?

Not in SugarDoc. Only the first 15 pages (6 on low-memory phones) are saved. For the whole document, ask the sender for a PDF or make it on a computer.

If I cancel on the save screen, is an empty file left behind?

No. Cancelling on the save screen creates no file.
