iOS 26 Disable Preview App: Alternatives to Deletion

If you don’t want to delete Preview completely, there are alternatives. You can change how files open without removing the app.

Option 1: Use Quick Look Instead

This method keeps Preview installed but bypasses it:

  • 1. Open the Files app
  • 2. Touch and hold a PDF or image
  • 3. Select “Quick Look” from the menu
  • 4. The file opens in Files instead of Preview

You need to do this each time though. It’s not a permanent setting. Quick Look offers basic viewing and markup tools.

Option 2: Change Default App Behavior

Make Files the default viewer again:

  • 1. Open the Files app
  • 2. Touch and hold any PDF
  • 3. Tap “Open With”
  • 4. Select “Preview with Quick Look”
  • 5. Repeat for images

This sets a preference for future files. New PDFs and images open in Files by default. The change applies across your iPhone.

Option 3: Hide Preview from Home Screen

Keep the app but remove visual clutter:

  • 1. Touch and hold the Preview icon
  • 2. Tap “Remove App”
  • 3. Choose “Remove from Home Screen”
  • 4. The app stays in App Library
  • 5. Access it only when needed

This approach gives you flexibility. Preview remains available but out of sight. You can launch it from App Library when necessary.

Option 4: Use Screen Time Restrictions

Limit Preview access through parental controls:

  • 1. Go to Settings > Screen Time
  • 2. Tap “Content & Privacy Restrictions”
  • 3. Enable restrictions if needed
  • 4. Go to “Allowed Apps”
  • 5. Toggle Preview off

This doesn’t delete the app but prevents opening it. It’s useful for managed devices or family sharing. The app remains installed but inaccessible.

Why Some Users Want to Disable Preview

Several reasons explain why users disable Preview:

Redundancy with Files App

Files already handled PDFs and images before iOS 26. Preview feels like an extra step to many users. Opening files in a separate app disrupts workflow.

Slower Navigation

Preview adds a bounce between apps. This creates delays when viewing multiple files. Users who browse folders quickly find this frustrating.

Learning Curve

Some people prefer familiar tools over new ones. The Files app’s interface was well-known. Preview introduces different menus and workflows.

Storage Concerns

Every app takes up space, even system apps. Users with limited storage might remove Preview. The space savings are minimal but noticeable.

Personal Preference

Some users simply don’t need advanced features. Basic viewing and sharing work fine in Files. Preview’s tools feel like overkill for simple tasks.
