WhatsApp birthday invitation in 1 minute

WhatsApp displays images full-screen inside a chat, so a vertical image makes the best use of the phone's screen. The recommended standard is 1080x1920 pixels, a 9:16 ratio.

If you would rather go square so it reads fully in the chat preview, use 800x800 pixels instead. Either way, leave a safety margin at the top and bottom: the clock, front camera or navigation bar can cover text set too close to the edge.

Save the file as JPG or PNG, never PDF: plenty of parents won't open a PDF on their phone, and a heavy file eats into the data plan of whoever receives it.

Design doesn't matter if a detail is missing. The invitation needs six details: the birthday child's name and the age they're turning, the date, start and end time, the venue with its full address, who to RSVP to and by when, and a closing note on pickup, allergies or gifts.

For ready-to-copy wording by age, check what to write on a birthday invitation before you draft the message.

If you would rather skip a design app and writing the text from scratch, FunPartyAI's AI invitation generator does the work for you: upload a photo of your child, pick a theme from the available templates, and add the date, time and place.

In under a minute you get an image already sized for WhatsApp, ready to download and send straight to the chat or the broadcast list, no cropping or margins to fix.

Always use a photo of your own child. If you want to include other kids in the design, ask their family for permission before you upload it — see how we handle photos in our privacy policy.

If you're inviting classmates, skip creating a brand-new group just for the party: folding every family into one extra chat multiplies the notifications for anyone who only wants to confirm one detail.

It's easier to send the invitation to each family individually, or use a broadcast list: everyone receives it as a direct message, without seeing who else is on the list.

If you're not inviting the whole class, hand it out away from the school group chat rather than posting it there: decide who's invited first so nobody finds out they were left off in front of everyone else.

By default, WhatsApp reduces the quality of the photos and images you share to save data, so a design with small text can end up hard to read once it lands in the chat.

Before sending, turn on HD quality from the image picker in the chat — it allows up to 5120 pixels wide or tall without cutting the resolution. For the exact file, with zero compression, send it as a document instead of a photo — the recipient has to tap to open it, but it arrives untouched.

Format matters, but timing matters more: send the invitation with enough advance notice so nobody's weekend is already booked by the time it lands.

Always include a reply-by date in the message itself. A simple "please RSVP by [date] to this number" saves you from chasing replies in the chat during the last few days.
