HWP Viewer - Hangul hwp·hwpx

Edit, fill & sign Hangul docs

Free · In‑App Purchases

Open Hangul documents right away — no ads, no sign-in. New: public forms page by page, signatures and stamps on iPhone and iPad (your iCloud), copying text. Open Hangul documents right away — no ads, no sign-in. Viewing Hangul documents is free. Try form saves (Hangul files, signed PDFs or page images, edited documents, documents with stamps or pen marks) and conversions (paper, photos or PDFs to Hangul; Word export) three times each for free; a one-time lifetime unlock (not a subscription) keeps both going. Saving a filled form as PDF without a signature is free. OPEN HANGUL FILES HWP and HWPX attachments are shown as laid out on the page: tables, pictures, text boxes, numbering, headers and footers, footnotes, equations, shapes and charts. FILL IN FORMS ON YOUR PHONE Open a Hangul form (reply slips, applications) and choose 더 보기 › 양식 채우기: the app lists the blanks in tables and text (such as "성명: ____ (서명)" or a date line), □ check boxes and choices such as "참가( ) 불참( )". After 완료, what you entered shows in the document, and you can save a new HWPX file marked (작성) or a PDF — the original stays. (Saving as a Hangul file works for HWPX documents; HWP documents are saved as PDF.) SIGN ON YOUR PHONE Where a form has a (서명) or (인) mark or a signature cell, draw your signature with a finger and it goes in that place in the PDF. It stays on this device and in your own iCloud (your iPad on the same Apple ID has it too); delete it any time. NOTHING LOST What you type and the text you change are kept on the device as you go; if the app closes, open the document again and choose 이어서 하기. TRY THE SAMPLE FORM Open the sample form (견본) in the app's folder to fill in, sign and save it; it does not use a free save. EDIT TEXT Fix a name, a date or a typo: choose 더 보기 › 글자 고치기, tap a paragraph or a table cell, and the change shows at once. It is saved as a new HWPX file marked (수정); the original stays as it was; 찾아 바꾸기 replaces the same words throughout at once. (HWP documents save the edited result as PDF.) STAMPS AND PEN MARKS Place a stamp photo with its background removed, mark with a pen, and save as PDF or a new HWPX file (더 보기 › 도장·펜 표시). Stamps reach your iPad the same way. EXPORT TO WORD Turn a Hangul document, as shown with entered values, edits and signature, into a .docx file for Pages, Word or Google Docs (더 보기 › 워드(DOCX)로 내보내기). PAPER, PHOTOS AND PDFS TO HANGUL Tap "PDF·사진을 한글 파일로" on the first screen, scan a page or pick a photo or PDF: the app reads the text and tables, makes an HWPX file you can edit in Hangul, and shows it at once. Files are saved in Files > HWP 뷰어 > 변환한 문서. WORD, EXCEL, POWERPOINT AND PDF TOO Word (docx, doc), Excel (xlsx, xls), PowerPoint (pptx, ppt), PDF, RTF and CSV attachments open here too (view only). FIT TO SCREEN, PAGES, FIND, READ ALOUD, PDF Reflow text, page list, night view, links, search with counts, copy text and tables, read aloud, character counts, Quick Look, and share as PDF or page images. PRIVATE BY DESIGN All processing, including text recognition, happens on your device. Documents are not uploaded; only your signature, stamps and trial counts go to your own iCloud. No ads, no subscriptions. Good to know - Conversion requires iOS 26 (viewing: iOS 18). - Recognition can make mistakes; check converted documents. Only text and tables are carried over, and a table that runs over several pages becomes one table per page. - Form filling lists only the blanks the app finds; some may be missed. The signature and pen marks go into PDFs and page images only (not into saved Hangul files); stamps also go into Hangul files saved from HWPX documents. - Word export re-flows lines and pages; equations, charts and drawings become pictures. - Some layout effects are simplified in the viewer; password-protected documents cannot be opened. The interface is in Korean. This product was developed with reference to Hancom's published HWP file format document. Hangul is a trademark of Hancom Inc.; this app is not affiliated with Hancom.
