How to Disable the Edit, Sign, and Share Pop-Up When Sending Files in LINE
Product
LINE App
Device & OS
Android, iOS, Windows, Mac
Scenario
Sending a document or PDF file to a contact through the LINE messaging app.
Observed behavior
An Edit, Sign, and Share pop-up from a third-party document integration interrupts the file sending process.
Before you start

Ensure your LINE app and default document or PDF reader apps are updated to the latest versions. Since the steps to change default apps vary, verify whether you are using an Android or iOS device.

Solution 1Recommended

Change Default App Settings on Android

Adjust your Android default app settings to prevent the associated document reader from intercepting the file sharing process.

The pop-up is usually triggered because a specific PDF or document editor is set as the default app for handling files on your device. Clearing this default setting allows you to bypass the prompt.

1
Open Device Settings

Navigate to your Android device's Settings app and select 'Apps' or 'Apps & notifications'.

2
Access Default Apps

Tap on 'Default apps' or 'App management' to view the applications currently handling specific file types.

3
Clear Defaults for the Document App

Locate the PDF or document handler (e.g., Adobe Acrobat) that is triggering the pop-up, tap on it, and select 'Clear defaults'.

4
Share the File Again

Go back to the file you want to send in LINE. When prompted, choose to open or share the file using a different application.

Change Default App Settings on Android
Default Cleared: Once the default is cleared, your device will ask you which app you want to use next time you open a PDF, allowing you to choose a less intrusive option.

Frequently Asked Questions

Why does the Edit, Sign, and Share pop-up appear when I share a file?

This pop-up usually comes from a third-party PDF or document editing app that has integrated itself as the default file handler on your device. When you trigger a share action, that app intercepts the process to promote its own premium features.

Will uninstalling my current PDF reader stop the pop-up in LINE?

Yes, uninstalling the application responsible for the pop-up will eliminate the prompt. However, if you still need to read PDFs, it is highly recommended to switch to a lightweight, non-intrusive alternative like WPS Office.

How do I attach a file directly inside the LINE app?

Open the chat in LINE, tap the '+' (plus) icon located next to the text input box, select 'File', and then browse your device's local storage to attach the document directly. This method usually bypasses external app pop-ups completely.
