We provide practical know-how that not only goes beyond simply pasting images to enhance the completeness of the document and edit neatly, but also guide you on how to work safely without concerns about file damage or data loss.

How to Insert Signatures or Seals in Korean Documents

Simply pasting a signature or seal image into a Korean document can leave background margins or cause misalignment.

By following the process below, you can complete a neat and professional document.


1. Preparing a Scanned Signature or Seal File (Removing Korean Signature Background)

After signing or stamping directly on paper, scan it using a scanner or smartphone app.

After inserting the signature image into the document, select it and run [Image] - [Photo Editing].

Methods for Recovering Damaged Korean (HWP) Files

Korean files, widely used in business, schools, and public institutions, can be damaged due to save errors. In such cases, utilize the recovery methods outlined below.

1. Recovering from Autosave Files

By default, Korean has an autosave function that operates at regular intervals.

If the autosave function is not applied, you can set it in the following path: [Tools] → [Environment Settings] → [File]

If you set ‘Always autosave’ to a specific time, it always autosaves according to the set time, regardless of the circumstance. ‘Autosave when idle’ automatically saves when no work is being done. Setting the interval shorter can be helpful if the working environment is unstable.

[File] → [Document Yard] → [Temporary Saved Documents] allows you to load recent autosave versions.


2. Utilizing Temporary Files (asv) for Recovery

If Korean forcefully exits during work, a temporary file like ~$filename.hwp is created.

You can find temporary files at Korean Information → Folder Information → Temporary Folder or C:\Users\YourUser\AppData\Local\Temp.

If you change the file extension of an asv file to .hwp and run it, some of the content can be restored.



📌 Precautions for Recovery and Tips for Preventing File Damage

Avoid overwriting damaged files; always attempt by creating a copy.

Setting the autosave interval to short (within 3 minutes) can minimize data loss.

For large files, use image compression or the ‘reduce Korean file size’ function to enhance stability.



Enhancing Korean Document Completeness with Transparent Background Signatures and File Recovery

With the insertion of transparent background seals or signatures, you can enhance the completeness of your documents. By mastering methods for recovering Korean files, temporary file recovery, and restoring from autosaves, you'll be able to handle urgent situations without disruptions. Whether you're a student, office worker, or public institution manager, make sure to practice these techniques to boost your work efficiency.
