See exactly how your Instagram or TikTok profile, bio and link will look before you publish. Live character counter included.
How to use the bio link preview
Pick Instagram or TikTok, then type your name, username, bio and link. The phone mock on the right updates live, so you can see line wraps, spacing and the link exactly as followers will. The counter keeps you under each platform bio limit.
Bio character limits
- Instagram: 150 characters, line breaks supported.
- TikTok: 80 characters, keep it punchy.
What makes a good bio
- Lead with who you help and what you do, in plain words.
- Use one clear call to action and one link.
- Break it into short lines so it scans on a phone.
- Skip filler. The first line is what people read.
Bio polished? PostSider keeps every connected profile in one place so you can manage and publish across them without switching apps.
FAQ
Bios, answered.
How many characters can an Instagram bio be?
An Instagram bio can be up to 150 characters. This preview counts as you type and warns you before you hit the limit, so nothing gets cut off when you publish.
How long can a TikTok bio be?
A TikTok bio is limited to 80 characters. Switch the preview to TikTok and the counter updates to that limit so you can write to the right length.
Why does my bio look different after I post it?
Apps truncate long bios, strip some line breaks and shorten links. Previewing first lets you see the real layout, catch awkward line wraps and confirm your link and name fit before it goes live.
Is my bio or photo uploaded anywhere?
No. Everything runs in your browser. The text you type and any photo you add for the preview never leave your device.
