How to Customize Plex Posters and Artwork

Published September 1, 2026 · 9 min read

A well-curated Plex library is not just about having the right content. It is about presentation. Default posters pulled from TheMovieDB or TheTVDB are functional, but they are often inconsistent: different aspect ratios, clashing art styles, and language mismatches. Custom posters transform a cluttered library into something that looks and feels intentional. This guide covers how to upload custom artwork, where to find high-quality poster art, how to automate bulk edits, and what resolutions to use for the sharpest results.

Uploading Custom Posters Manually

The simplest way to change a poster is through the Plex Web interface. This works for individual movies, TV shows, seasons, episodes, and collections.

For a Movie or TV Show

1. Navigate to the item in the Plex Web app.
2. Click the pencil icon (Edit) or right-click and select "Edit."
3. In the edit panel, select the "Poster" tab.
4. You will see the current poster and alternatives that Plex found from metadata sources. Click "Upload Poster" to add your own image file.
5. Select a JPG or PNG from your computer. Plex will crop it to the standard poster aspect ratio (2:3).
6. Click "Save Changes."

For a Collection

Collections are where custom posters make the biggest visual impact. A set of matching collection posters for franchises like Marvel, Star Wars, or Lord of the Rings creates a cohesive look on your home screen. The process is the same: open the collection, click Edit, go to the Poster tab, and upload.

For Backgrounds (Art / Fanart)

In addition to posters, each item in Plex can have a background image (sometimes called "art" or "fanart"). This is the wide image that appears behind the title when you view its detail page. Edit the item, switch to the "Background" tab, and upload a landscape image. The recommended aspect ratio is 16:9.

Where to Find Custom Poster Art

The Plex community has produced an extraordinary amount of custom artwork. Here are the best sources:

The Poster Database (ThePosterDB / TPDB)

ThePosterDB at theposterdb.com is the single most popular source for Plex-specific custom posters. Users upload sets of matching posters for movie franchises, TV shows, and collections. The quality is generally very high, and many creators produce complete sets with consistent styling across an entire franchise.

You can search by movie or show title, browse by popularity, or follow specific creators whose style you like. Most posters are available in high resolution and can be downloaded directly as JPG files.

FanArt.tv

FanArt.tv provides a wide range of artwork including posters, backgrounds, logos, and disc art. It is community-driven and covers movies, TV shows, music, and more. The artwork tends to be more diverse in style compared to TPDB. Plex can also use FanArt.tv as a metadata source for automatic artwork, but downloading manually gives you more control over which specific image you use.

r/PlexPosters on Reddit

The r/PlexPosters subreddit is an active community where artists share their custom poster work. It is a great place to find unique artwork that may not be on the larger databases yet. Creators often post full franchise sets, seasonal artwork, and minimalist designs. The subreddit is also a good place to request custom posters for niche titles.

MediUX

MediUX at mediux.pro is a newer platform that has grown quickly in the Plex community. It focuses on curated sets with consistent styling and supports direct integration with some automation tools.

Creating Your Own

If you have design skills, creating your own posters gives you complete control over the aesthetic. Tools like Photoshop, Affinity Designer, GIMP, or even Canva work well. Start with the recommended resolution (see below), use a 2:3 aspect ratio, and include the title text in a readable font. Many creators use high-resolution movie stills or promotional images as a starting point and add their own typography and effects.

Recommended Resolutions

Using the right resolution ensures your posters look sharp on high-DPI displays and large screens without being unnecessarily large.

Keep file sizes reasonable. A 2000 x 3000 JPEG at quality 90 is typically 500 KB to 2 MB, which is perfectly fine. Avoid uploading uncompressed PNGs above 10 MB; they consume unnecessary storage and provide no visible quality benefit after Plex processes them.

Bulk Editing with Plex Meta Manager

Manually uploading posters works for a handful of titles, but if you want to overhaul your entire library, Plex Meta Manager (PMM) automates the process at scale.

What PMM Does

PMM is a community-built Python tool that connects to your Plex server and applies metadata changes based on configuration files. You can define rules that automatically set posters, create collections, apply labels, and manage overlays across your entire library.

Using PMM for Poster Management

1. Install PMM. It runs as a Docker container or directly with Python. Docker is the recommended approach for most users.
2. Configure your Plex server connection. PMM needs your server URL and an authentication token.
3. Create a configuration file. Define which libraries to manage and what rules to apply. For posters, you can point PMM at ThePosterDB sets, local image folders, or URL lists.
4. Run PMM. It connects to your server, evaluates each item against your rules, and applies changes. A full library pass might take 10 to 30 minutes depending on library size.
5. Schedule regular runs. PMM can run on a schedule (via cron or Docker's restart policy) to automatically apply posters to newly added content.

PMM Overlays

One of PMM's most popular features is overlays. These are small badges added to poster images that show information like resolution (4K, 1080p), HDR format (Dolby Vision, HDR10), audio format (Atmos, DTS-X), or media source (Blu-ray, Remux). Overlays do not replace the poster; they add a small visual tag in a corner. This lets you see at a glance which version of a movie you have without opening the detail page.

Organizing Collection Posters

Collections are where custom artwork has the most visual impact. A well-designed collection poster set makes your library home screen look professional. Here are some tips:

• Use matching sets. Find or create poster sets where every collection poster shares the same art style, typography, and color palette. ThePosterDB creators often publish complete franchise sets.
• Prioritize franchise collections. Start with your most prominent franchises: Marvel, Star Wars, Harry Potter, James Bond, Lord of the Rings, and similar series. These appear on the home screen and set the visual tone for your library.
• Set a collection mode. Under each collection's settings, choose whether the collection appears as a single poster (hiding individual titles from browse view) or alongside individual titles. For large franchises, hiding individual titles behind the collection poster keeps the browse view cleaner.
• Create genre or mood collections. Beyond franchises, consider themed collections like "90s Classics," "Weekend Comfort," or "Award Winners." Custom posters for these add personality.

Maintaining Your Artwork

Custom posters require occasional maintenance:

• Back up your posters. If you run a metadata refresh or reinstall Plex, custom uploads can be lost. Keep a local folder of all your custom poster files, organized by movie or collection name. See our Plex backup guide for protecting the Metadata folder.
• Check for conflicts after metadata refreshes. A full metadata refresh can revert custom posters to defaults. After refreshing, spot-check your most important titles.
• Update for new additions. When you add a new movie to a franchise, check if your poster set creator has released a matching poster for it.

Common Issues

Poster appears blurry. The source image resolution is too low. Re-download or find a higher-resolution version. Aim for at least 1000 x 1500.

Poster reverted after metadata refresh. A library refresh can overwrite custom posters. To prevent this, lock the metadata field after uploading. In the edit panel, click the lock icon next to the poster field.

Poster not showing on some clients. Clear the image cache on the affected client app. On iOS, this is under Plex Settings and then Advanced. On Apple TV, try removing and reinstalling the app.
