How to Upload Custom Artwork in the Plex Mobile App: A Step-by-Step Guide

Introduction

Plex has just released a major update for its Android and iOS apps, introducing a highly requested feature: the ability to upload custom artwork directly from your phone or tablet. Previously, you had to switch to the Plex Web Dashboard to set custom posters or background images for your media. Now, you can do it all on the go, making it easier than ever to personalize your library. This guide will walk you through the process step by step, from preparing your files to applying the final touch.

What You Need

• A Plex Media Server – running and connected to your library.
• The Plex mobile app – updated to the latest version (Android or iOS).
• A Plex account – signed in to both the server and the app.
• Custom artwork files – images saved on your device (typical formats: JPG, PNG, WebP; recommended size: at least 1000x1500 pixels for posters).
• A stable internet connection – or local network access to your Plex server.

Step-by-Step Guide

Step 1: Open the Plex App and Navigate to Your Media

Launch the Plex app on your Android or iOS device. Make sure you are logged in to the same account used for your Plex Media Server. Browse to the movie, TV show, or music album you want to customize. For example, tap on Movies and select a title from your library.

Step 2: Access the Item’s Details

Once you’ve selected a media item, you’ll see the main details screen. Look for the more options button (usually three dots or a gear icon). Tap it to open the context menu. From the menu, choose Edit or Manage (the exact wording may vary slightly by app version).

Step 3: Locate the Artwork Section

Inside the editing screen, you’ll find a section labeled Artwork or Poster. This is where all the available images are displayed, including those automatically matched by Plex. At the top or bottom of this section, you should see an option to Upload Custom Artwork or a plus (+) icon.

Step 4: Choose an Image from Your Device

Tap the upload button. Your device’s file picker will open. Navigate to the folder where your custom artwork is stored. Select the image you want to use. Confirm your selection – the app may briefly show a loading indicator as it processes the file.

Step 5: Apply the New Artwork

After the upload finishes, the new image will appear in the artwork list alongside the existing ones. Tap on it to select it as the active poster or background. A checkmark or highlight will indicate it’s chosen. Then, tap Save or Apply (usually at the top right corner).

Step 6: Verify the Change

Return to your main library screen. The updated artwork should now be visible. You might need to refresh the page or pull down to reload. If it doesn’t appear immediately, wait a few seconds and check again – Plex syncs changes across devices automatically.

Tips for Best Results

• Use high‑resolution images – Plex scales artwork, so start with at least 1000px on the longest side to avoid blurriness.
• Stick to standard aspect ratios – Posters are typically 2:3 (e.g., 1000×1500). Backgrounds (fan art) work best at 16:9 or 4:3.
• Name your files clearly – While not required, a descriptive filename helps if you ever need to re‑upload.
• Check file size – Most images under 10 MB upload smoothly. Larger files may take longer or fail on slow connections.
• Use the mobile app for quick edits – This feature is perfect for on‑the‑go adjustments, but for bulk changes consider using the web dashboard.
• Remember that artwork is per‑item – If you have multiple versions of the same movie (e.g., 4K and HD), each needs its own artwork.
• Refresh your library – If changes don’t reflect, try refreshing the metadata in the server settings or restarting the app.
• Keep backups of your original images – In case you accidentally overwrite a custom poster you liked.

Conclusion

The Plex mobile app now puts full control over your media’s visuals right in your pocket. With just a few taps, you can replace auto‑generated posters with your own favorites, making your library feel truly yours. Whether you’re a movie buff curating a movie night collection or a music lover setting album covers, this update eliminates the need to switch to a desktop. Try it out today – you’ll wonder how you managed without it.
