This page opens the editor with **Age** set to 21 in Story 9:16\. Below: ideas that suit a 21st, and how to get clips from friends in other time zones without spoiling the surprise. The editor works in your browser, so nothing is uploaded. Free, no watermark, no account. Start from one of these ## Happy 21st birthday wishes For a card, a toast or a GIF in the group chat. Paste one into **Message**. * Happy 21st birthday. The key to the door is yours. * Twenty-one and the whole world in front of you. * Happy 21st. Officially an adult in every country now. * Three years of practice at being a grown-up. Today it counts. * To twenty-one: may it be loud, kind and unforgettable. * Happy 21st from every city your friends have ended up in. * We knew you at seven. We are very proud of you at twenty-one. * Here’s to the friends you made, the ones you kept and the ones still to come. * Twenty-one candles, one wish, endless possibilities. * Happy birthday. Please don’t lose the key. * The first twenty were the trailer. This is the film. * Happy 21st, with love from home. ## How to make a 21st birthday video 1. ### Open a 21st template Press **Make a 21st birthday video**. **Age** is set to 21; choose a look in **Templates**. 2. ### Write the card Type their name in **Name** and a wish in **Message**, such as “The key to the door is yours”. 3. ### Add photos and clips Press **Add photos and clips**: the best photo from each year since 18, then the clips friends sent. 4. ### Music and export Press **Add music**, then **Export video** and **Share**. For the chat, press **Export video** and choose **GIF**. ## Ideas that suit a 21st Twenty-one has its own traditions. In the UK, Ireland, Australia and New Zealand it is the age of the “key to the door”, and a big silver key often appears on the cake. Ideas that fit: * **The key.** Use the key line in **Message**, or end on a photo of the actual key if there is one. * **Three years at a glance.** The best photo from each year since they turned 18: leaving school, the first term away, the summer job, the trip. * **Friends from every chapter.** A clip from a school friend, one from a flatmate, one from a colleague. * **A look ahead.** Ask a parent or grandparent to say what they hope the next ten years bring. ## Getting clips from friends abroad By 21, close friends are often in different cities or countries. One person puts the video together; there is no shared upload page, so everyone sends their clip to you. ### Making it easy for people far away * Give a deadline in their time zone, a few days before the birthday. * Ask for clips filmed upright, in daylight, with the phone held still. * Messaging apps can shrink videos; sending a clip as a file keeps the full quality. The [WhatsApp status](https://birthday.video/happy-birthday-whatsapp-status) page explains the difference. * Ask people to start with their name and where they are (“Hi from Melbourne”), which makes the distance part of the story. The [birthday montage](https://birthday.video/birthday-montage) page covers collecting clips from a big group, secret included. ## One video, two shapes If it will play on a screen at the party and also go to the group chat, export it twice. Set **Format** to Landscape 16:9 for the screen, then switch to Story 9:16 and press **Export video** again for phones. The project is saved in your browser, so changing the shape loses nothing. ## Happy 21st birthday: questions ### What does “key to the door” mean on a 21st? It goes back to 21 being the old age of adulthood, when a young person was trusted with their own key to the family home. Many 21st cakes and cards still show a silver key. ### What should I write for a 21st birthday? Something about this new chapter and the people around them: their name, a nod to the key or to coming of age, and a warm wish for what comes next. ### Can I send it as a GIF? Yes. Press **Export video** and choose **GIF**. A GIF loops on its own and has no sound, which suits a group chat. ### Can friends who live abroad take part? Yes. They film a short clip on their phone and send it to you; you add it with **Add photos and clips**. ### Is it free? Yes. No watermark and no account, and the photos and clips stay on your device. ## Other birthdays and ideas * [ Birthday video maker Start from an animated template, add their name, photos and a song. ](https://birthday.video/) * [ Happy 18th birthday wishes and videos Wishes for an 18th and a baby-to-grown-up video with messages. ](https://birthday.video/happy-18th-birthday) * [ Happy 30th birthday wishes and videos A kind roast or a tribute, as a GIF or a video of their twenties. ](https://birthday.video/happy-30th-birthday) * [ Birthday montage from friends A clip from everyone, put together into one surprise tribute video. ](https://birthday.video/birthday-montage) * [ Happy birthday friend GIF and video Wishes for a friend or best friend, a GIF with their name, or a video of your photos. ](https://birthday.video/happy-birthday-friend) * [ Happy birthday daughter GIF and video Wishes from a proud parent, a GIF with her name, or a year-by-year video. ](https://birthday.video/happy-birthday-daughter) * [ Happy birthday son GIF and video Proud-parent wishes, a GIF with his name, or a video of him growing up. ](https://birthday.video/happy-birthday-son) * [ Birthday video templates Every template in the editor, by occasion, with the formats it suits. ](https://birthday.video/birthday-video-templates)
