10 Best WhatsApp Web Themes in 2026 (Free JSON Downloads)

WhatsApp Web looks the same for everyone — the same green, the same layout, the same default everything. It doesn't have to. With a free extension and a JSON file, you can change the entire look of WhatsApp Web in about ten seconds.

This post is a bit different from most "best themes" lists. Every theme below comes with a downloadable JSON file you can import directly into WhatsApp Web Customizer. No manual color-picking, no building anything from scratch. Download, import, done. Pick the look you like, grab the file, and your WhatsApp Web is transformed.

Here are ten of the best, across every style — dark, light, OLED, retro, and full aesthetic recreations.

First: How to Use These Theme Files (10 Seconds)

Every theme below has a Download JSON button. Here's how to use it:

Install WhatsApp Web Customizer if you haven't (free, open source, ~30 seconds)
Download the theme JSON file you want from below
Open web.whatsapp.com and click the extension icon
Go to the Themes tab → Import
Select the downloaded JSON file
The theme applies instantly

To switch themes later, just import a different file — or save several and swap between them from your Custom themes. That's the whole workflow.

New to importing themes? We have a full walkthrough in how to install custom themes on WhatsApp Web.

1. Midnight — Deep Dark, Easy on the Eyes

(Tip: pair this one with a monospace font like JetBrains Mono for the full effect — see best monospace fonts for WhatsApp Web.)

How to Make These Your Own

Every theme above is a starting point, not a locked preset. Once you've imported one, you can open it in the Theme editor and tweak anything — nudge the accent, deepen the background, swap the bubble colors. The imported theme becomes a custom theme you fully control.

And because each is a JSON file, you can:

Save multiple and switch between them (a light theme for day, dark for night)
Share them with friends — send the JSON file and they import it the same way
Edit them in a text editor if you're comfortable with that — each -- value maps to one part of the interface

Pair Your Theme With the Right Font

A theme sets the colors; the font sets the feel. Most of these themes pair beautifully with a considered font choice:

Dark themes (Midnight, Dracula, Nord): Inter or JetBrains Mono
Light themes (Clean Light, iMessage, Telegram): Inter or DM Sans
Warm themes (Sunset): Lato or Open Sans
Terminal Green: any monospace, for the full retro effect

See our full guides: best fonts for WhatsApp Web and how to pair fonts and themes.

The Bottom Line

You don't have to build a WhatsApp Web theme from scratch to have a great-looking setup. Download one of the ten above, import it in ten seconds, and you're done — or use it as a base and make it your own.

All ten are free. The extension is free and open source. And if you build something you love, you can share the JSON file with anyone.
