Open and edit PDF, HWP, HWPX, and DOCX documents directly.

▸ Signature vault
Save frequently used signatures and stamps for quick access next time. The vault is protected with biometric authentication or your device passcode.

Korean, English, Japanese, German, French, Spanish, Portuguese, Indonesian, Traditional Chinese, and Hindi are supported.
