Free Link in Bio Preview Tool

A link in bio preview tool is a free online mockup designer that shows you exactly how your bio page will look on a mobile phone before you publish it on Instagram, TikTok, Twitter, or YouTube. You enter your name, handle, short bio, profile photo, and the buttons you want to feature, and the tool renders a live phone-frame preview in real time. This is useful because the platforms that drive most of your bio traffic, Instagram and TikTok, are nearly 100% mobile, so you need to design for a small screen first. Our link in bio preview lets you experiment with button copy, ordering, accent colors, and the length of your bio text without committing to any platform or tool. Once you are happy with the design, you can rebuild it on UseClick or another link-in-bio service with confidence.

Instagram historically restricted profile bios to a single clickable link to keep the platform clean and to prevent spam. Even though Instagram now allows up to five links via the link sticker feature on profiles, the practical reality is that creators and brands still need a destination page that gathers all of their offers, products, and content into one place. That is exactly what a link-in-bio page does. The same constraint applies to TikTok, which gives business and creator accounts a single bio link, and to legacy Twitter and Bluesky profiles. A well-designed link-in-bio page solves the one-link limit by acting as a hub: visitors land on your page, scan the buttons, and tap whichever destination matches their intent. Our link in bio preview tool helps you design that hub on mobile-first.

The data on link-in-bio pages consistently shows that fewer links convert better. Linktree's own 2024 benchmark report found that profiles with 5 to 7 visible buttons get roughly 1.6 times more clicks per visitor than profiles with 12 or more. The reason is decision fatigue: when a visitor scrolls a wall of buttons, they freeze and bounce. Our preview tool caps you at 8 buttons on purpose. If you have more than 8 things to promote, group them into folders or rotate the buttons each week based on what you are actively pushing. Lead with the offer or content you most want clicks on, then descend to lower-priority items. The button at the very top of your bio page typically receives 38-45% of all clicks, so make it count.

Yes, your design is automatically saved to your browser's local storage every time you change a field. This means you can close the tab, restart your browser, and come back later, and your mockup will be exactly as you left it. Nothing is sent to our servers, so your draft stays private to your device. If you want to start over, click the Reset button to load the default sample bio. If you switch browsers or devices, your saved design will not transfer, so copy the JSON snapshot using the Copy Design button if you need to move it between machines. Note that clearing your browser cache or using incognito mode will also clear the saved design.

For a link-in-bio page, your profile picture should be at least 400x400 pixels and ideally 800x800 pixels, served as a square image. Most bio-link platforms display the avatar at roughly 96-128 pixels rendered size on mobile, but retina displays request 2x and 3x the pixel density, which is why a larger source image looks dramatically sharper. Use a face-forward photo with good lighting and a plain background for maximum recognizability at small sizes. If you are a brand rather than a personal creator, use a vector logo exported as a high-resolution PNG with transparency. Avoid full-body shots, group photos, or busy backgrounds, as they become unreadable when scaled down to a tiny circle. Our preview shows the avatar at its real rendered size on a phone screen so you can verify it before publishing.

Linktree and Beacons are full link-in-bio platforms where you actually host your bio page and direct your Instagram or TikTok traffic. Our tool is a free preview and design sandbox, not a hosting product, so you can experiment with the look and copy of your bio page without committing to any platform or paying a subscription. Once you have nailed the design, you can recreate it on Linktree, Beacons, or UseClick's link-in-bio feature, which is included free in every UseClick account. The advantage of using UseClick for your live bio page is that every button on it becomes a tracked short link automatically. You get click counts, geographic data, device breakdowns, and the option to point a custom domain at your bio page so the URL says yourbrand.com/links instead of linktr.ee/yourbrand.
