How to Open HWP Files on iPhone and iPad

Why your iPhone can't open HWP

iOS Quick Look previews PDFs, Word files and photos, but not HWP or HWPX — the native formats of Hancom's Korean word processor “Hangul”. Tapping the attachment shows just an icon or a “can't preview” message.

Korean schools, government offices and companies still send most documents as HWP, so this is a common wall for iPhone users in and outside Korea.

Method 1: Convert to PDF in Safari

Save the attachment to Files first. In Mail, long-press the attachment and choose Save to Files; in KakaoTalk or other messengers, use the share button and pick Save to Files.

Open anyview.dev in Safari, tap “Choose files” and select the HWP. Tap “PDF” and the converted file lands in your Downloads folder in Files.

Conversion happens on the phone itself — the document is never uploaded, which matters for IDs, contracts and school forms.

Method 2: Open it directly with the AnyView app

Install AnyView – File Viewer from the App Store. Then choose AnyView from the share sheet in Mail, KakaoTalk or Files to read the HWP instantly, even offline. The app also opens 200+ other formats.

For a one-off file, the website is enough; if HWP shows up every week, the app saves steps.

On iPad

The steps are identical. The bigger screen makes it handy to convert several HWP files at once and combine them with “One PDF”, then annotate the PDF with Apple Pencil.

Troubleshooting

Password-protected HWP files can't be converted — ask the sender for an unlocked copy.

If a Korean font isn't available, a similar one is used, so line breaks may shift slightly. Text, tables and images stay intact.
