A blank document can feel a little, well, blank. Lark Docs lets you add a cover image above your document title to give it personality and polish — choosing from a gallery of high-quality images (including animated ones) or uploading your own.
But here’s the thing: a cover image is more than decoration. Used thoughtfully, covers make your documents easier to recognise, organise, and navigate — for you and for everyone you share them with.
This guide shows you how to add and edit covers in Lark Docs, and just as importantly, how to use them to work smarter.
Why Cover Images Matter (More Than You Think)
It’s easy to dismiss document covers as purely cosmetic. But in a busy workspace where your team creates dozens or hundreds of documents, covers quietly do a lot of useful work:
Faster recognition
A distinctive cover acts as a visual landmark. When you’re scanning a list of documents or flipping between tabs, you recognise “the one with the blue wave cover” far faster than reading through similar-looking titles. Your brain processes images much quicker than text.
Easier organisation
Covers can become a visual coding system. Use a consistent colour or style for each document type — for example, calm blue tones for reports, warm tones for meeting notes, vibrant images for creative briefs. Over time, your team learns the system and can identify a document’s purpose at a glance, before reading a single word.
Smoother navigation
In shared spaces and wikis where many documents live together, covers help everyone find what they need faster. A well-chosen cover makes an important document stand out from the routine ones, reducing the time your team spends hunting for the right file.
A more professional impression
When you share a document with clients, partners, or leadership, a clean cover signals care and attention to detail. It elevates an ordinary doc into something that looks considered and polished — which reflects well on you and your business.
Stronger team identity
Consistent, branded covers across your team’s documents create a cohesive, professional feel. It’s a small touch that makes your shared workspace feel intentional rather than chaotic.
In short: covers aren’t just about looking nice. They’re a lightweight tool for organisation and clarity. With that in mind, here’s how to use them.
Step 1: Add a Cover
Adding a cover takes just one click.
- Open the document you want to personalise.
- Hover over the document title.
- Click Add Cover.
A random cover image will be automatically added above the title.
Step 2: Change the Cover Image
Once a cover is added, you can swap it for something more fitting.
Hover over the cover image and click Edit Cover > Select Image.
On the Gallery tab, choose from over 60 high-quality images (including animated ones). Or click Upload an Image to use your own.
You can also click Random to set a random image from the gallery as the cover. Clicking Random again will switch to another random image — a fun way to browse options quickly.
Step 3: Reposition the Cover Image
If your image is larger than the cover display area, you can choose exactly which part shows.
Hover over the cover image and click Edit Cover > Reposition Image.
Drag the image to adjust which part is visible, then click Confirm.
Step 4: Remove a Cover
If you’d rather have no cover, removing it is just as easy. There are two ways:
Hover over the cover image and click Edit Cover > Delete Cover.
Or hover over the cover image and click Edit Cover > Select Image > Delete.
Putting It Into Practice: A Simple Cover System
Want to get the organisational benefits without overthinking it? Here’s a simple system you can adopt with your team:
- Reports & analytics → cool blue or teal tones
- Meeting notes → warm orange or yellow tones
- Project plans → green tones
- Policies & official docs → minimalist or neutral covers
- Creative & brainstorms → vibrant, colourful images
Once your team gets used to the colour coding, everyone can identify a document’s type instantly — turning a cosmetic feature into a genuine productivity habit.
