WhatsApp Business image size guide
Use the correct dimensions and format to avoid rejection during Meta template approval and prevent cropping on delivery.
| Message type | Recommended size | Aspect ratio | Max file size | Formats |
|---|---|---|---|---|
| Template header image | 800×418px – 1200×628px | 1.91:1 | 5 MB | JPEG, PNG |
| Carousel card image | 1125×600px | 1.91:1 (required) | 5 MB | JPEG, PNG |
| Regular chat image | 800×800px | 1:1 (recommended) | 5 MB | JPEG, PNG |
| WhatsApp Status | 1080×1920px | 9:16 | 16 MB | JPEG, PNG |
| Link preview (OG image) | 1200×630px | 1.91:1 | 600 KB | JPEG, PNG, WebP |
| Business profile picture | 640×640px | 1:1 | 5 MB | JPEG, PNG |
WhatsApp re-encodes images on delivery to 60–100KB. Use bold, high-contrast designs and avoid small text for best results after compression.
How WhatsApp Business template messages work
WhatsApp Business API messages sent outside the 24-hour customer service window must use pre-approved message templates (also called HSMs). A template has up to four components:
- Header — an image (800×418px), video, document, or text. This is where your Wafrow dynamic image URL goes.
- Body — the main message text, up to 1,024 characters, with named or positional variables (
{{1}},{{first_name}}) that your platform replaces per recipient at send time. - Footer — a short line of gray text, typically used for opt-out notices (max 60 characters).
- Buttons — up to three call-to-action (URL, phone) or quick-reply buttons.
Templates must be submitted to Meta for approval before first use. Approval typically takes a few minutes to 24 hours. Once approved, the same template can be reused across campaigns.
WhatsApp image size by platform
Most platforms follow Meta's 800×418px guideline, but some have additional requirements or UI quirks worth knowing before you submit your template.
Klaviyo's WhatsApp channel (launched 2024) requires a 1.91:1 aspect ratio header image. The recommended size is 800×418px. Klaviyo passes the image URL as the header.example.header_handle parameter when submitting the template to Meta. Use Klaviyo Liquid tags in the URL for per-recipient personalization.
Braze supports both image and video headers. For image headers, use 800×418px (1.91:1). Braze fetches and caches the image server-side before delivery. Dynamic Braze Connected Content or Liquid can be used inside the image URL to personalize it per recipient at send time.
WATI (popular with Shopify and SMB brands) accepts images up to 5MB in JPEG or PNG. The image is uploaded directly in the WATI template editor, not via URL — export your Wafrow image and upload it, or use the Wafrow API to generate images programmatically per campaign.
These platforms pass the image as a media URL in the API payload. The recommended size is 800×418px at 1.91:1. For Interakt (popular with Indian Shopify merchants), use PNG for text-heavy graphics to avoid JPEG compression artifacts after WhatsApp re-encodes on delivery.
Personalize your WhatsApp image per recipient
Wafrow generates a unique image for every recipient by embedding their data into the image URL. Your WhatsApp platform passes the personalized URL as the header media when sending the template — no manual image exports or per-user design work required.
| Platform | Variable syntax in Wafrow URL |
|---|---|
| Braze | ?title[text]={{ ${first_name} }} |
| Intercom | ?title[text]={{first_name}} |
| Klaviyo | ?title[text]={{ person.first_name }} |
| Twilio / 360dialog | Pass as a template variable at API call time |

Frequently asked questions
What is the ideal image size for WhatsApp Business template messages?
For WhatsApp Business API template header images, the recommended size is 800×418px with a 1.91:1 aspect ratio. Meta accepts images up to 1200×628px for this slot. Keep the file under 5MB and use JPEG or PNG format. Using the correct aspect ratio prevents the image from being cropped or letterboxed when your message is delivered.
What is a WhatsApp Business template message?
A WhatsApp Business template message (also called an HSM — Highly Structured Message) is a pre-approved message format used to reach customers outside the 24-hour messaging window. Templates can include a header (image, video, or document), a body with variable placeholders like {{1}} or {{first_name}}, an optional footer, and up to three call-to-action or quick-reply buttons. Templates must be approved by Meta before first use.
Why is my WhatsApp Business image getting cropped?
WhatsApp crops images that do not match the expected 1.91:1 aspect ratio for template headers. If your image is square (1:1) or portrait-oriented, WhatsApp will center-crop it. Always use an 800×418px or 1200×628px image for template headers to avoid cropping. For regular chat images, keep important content in the center 70% of the frame as edges may be trimmed on some devices.
Does WhatsApp compress images sent via the Business API?
Yes. WhatsApp re-encodes images on delivery, typically outputting 60–100KB regardless of upload size. This means pixel-perfect quality is not guaranteed — use bold, high-contrast designs and avoid small text. PNG format tends to compress more cleanly than JPEG for graphics and text-heavy images.
Do WhatsApp images look different on iOS vs Android?
There are subtle differences. Android applies more aggressive compression (60–80KB output vs 80–100KB on iOS) and has slightly larger, more rounded chat bubbles post-2024. Template header images render full-width on both platforms, but iOS may show a slightly taller crop area. The safe recommendation is to keep critical content — logos, text, CTAs — in the center 70% of the image frame.
Which platforms support WhatsApp Business API image messages?
Braze, Klaviyo, Intercom, Twilio Flex, MoEngage, WATI, 360dialog, Insider, Respond.io, AiSensy, and any Meta-approved WhatsApp Business Solution Provider (BSP) support image header templates. You set the media URL in the template configuration and the platform delivers it to your recipients.
Can I personalize the WhatsApp image per recipient?
Yes. With Wafrow's dynamic image URL, you can pass any recipient data as a URL parameter — first name, order number, product name, discount code — and Wafrow renders a unique image for each user. Your WhatsApp platform passes this personalized URL as the media header when sending the template.
Does WhatsApp support animated GIFs in Business messages?
WhatsApp Business API template headers support JPEG and PNG only — not GIF or animated formats. For animated content, you can use an MP4 video header instead, though this requires a separate template approval from Meta.
