AI WhatsApp Broadcast Image for Restaurant Promos: A Practical Guide

By Lyxvo · Published November 2, 2026 · 4 min read

An AI WhatsApp broadcast image for restaurant promos is a single visual that tells your customers about a deal, a new dish or a limited offer in one glance. This guide shows you how to plan it, write the text, size it correctly and design it quickly with Lyxvo AI.

WhatsApp broadcast lists reach customers who already know your restaurant, which makes them a good channel for promotions. A clear image often does more work than a long message: people scroll fast, and the picture is what they see before they decide to read.

Why an image works better than text alone

A broadcast with only text can look like spam, especially when it is long. A well-made image with one dish, one offer and one call to action is easier to scan. Keep three things in mind:

• The offer should be readable on a phone screen without zooming.
• The image should match your brand so customers recognize it instantly.
• The message should point to one action, such as booking a table, ordering or visiting on a specific day.

Plan the promo before you design

Before opening any design tool, write down the following in a short list:

1. The offer: for example, "Weekday lunch set, 20% off" or "New chili crab, this week only."
2. The date window: start and end dates, so customers know when it expires.
3. The action: reserve, order, or come in.
4. The contact or link: a phone number, a menu link or your address.
5. The hero visual: a photo of your best-looking dish, your interior or your team.

A promo with a clear end date tends to read as more urgent. Only state dates and discounts you can actually honor, and check that your staff know about the offer.

Write short, specific copy

Your image should carry a headline of a few words, a supporting line and a small footer. Examples:

• Headline: Lunch Set for 2, Rp 99K
• Supporting line: Weekdays 11:00 to 14:00, dine-in only
• Footer: Book on WhatsApp at [your number] · Valid until 30 November

Avoid crowding the image with every item on the menu. One hero dish is stronger than a grid of ten.

Use the right size and format

WhatsApp displays images best in a vertical or square format, so most restaurants use one of these:

Keep text away from the outer edges so nothing is cut off, and export in a compressed format so the file loads quickly over mobile data.

Design the image in Lyxvo AI

Lyxvo AI includes a design agent that can generate social media posts at exact sizes for several platforms, along with a Canva-style editor where you can change text, photos and colors directly. For a WhatsApp promo, a practical workflow looks like this:

1. Open the social media post generator or the Instagram post studio and choose a square or portrait layout.
2. Describe your promo in plain language: the dish, the price, the time window and your brand colors. The agent produces a starting design.
3. Replace the placeholder photo with a real photo of your dish, then edit the headline, price and footer directly in the editor.
4. Use Magic Resize to adapt the same design to another size, for example a square version for Instagram from your portrait WhatsApp version.
5. Export a PNG at its real size and send it through your WhatsApp Business broadcast list.

If you also need a printed table tent or window poster for the same promo, the flyer maker and the poster maker let you reuse the same branding.

Note: Check current plan limits and prices on the pricing page before you commit to a plan. Lyxvo Lite includes a daily limit, so plan your promo batch accordingly.

Build a reusable promo template

If you run promos every month, save your layout once and swap only the dish, price and dates. This keeps your branding consistent and saves time. You can start from the free design templates library and adjust the colors and fonts to match your restaurant.

Checklist before you send

• The offer, price and dates are correct and approved.
• The dish photo is sharp and well lit.
• The text is readable at phone size.
• The call to action is one clear step.
• Your phone number or link is correct and tested.
• The file is exported at a reasonable size for mobile loading.
• You have sent a test to your own phone first.
• You are only messaging customers who have opted in to your broadcast list.

Measure and adjust

Keep a simple log for each promo: the offer, the send date, how many bookings or orders you received, and any feedback from staff. Over a few months this shows you which offers and visuals work best for your customers. Lyxvo AI can help you produce each variation quickly, so you can test a few headlines or photos without starting from scratch every time.

Summary

A good AI WhatsApp broadcast image for restaurant promos has one clear offer, a strong hero photo, short readable text, the right size and one call to action. Plan the promo first, write tight copy, design in a tool that exports at exact sizes, and keep a reusable template so each new promo takes minutes rather than hours.
