Social Media
Resizers, hashtags, captions and creator utilities.
Social media tools handle the small, fiddly jobs that come with posting to platforms like Instagram, YouTube, and X. This category covers resizing images to the right dimensions, counting characters against a post or bio limit, formatting captions, generating hashtags, working out an engagement rate, and making a QR code for a link-in-bio. Creators, social managers, and anyone running an account reach for these while putting a post together.

Frequently asked questions
- Are the social media tools free, and do I need to sign up?
- Every social media tool here is free, with no account or sign-up required. There are no usage limits, so you can resize as many images or count as many captions as you need. You do not connect any of your social accounts to use them.
- Do I need to install an app?
- No. These social media tools run in a normal web browser on desktop or mobile, so there is nothing to install. Most of them run entirely in the browser, which is handy when you are drafting a post from your phone.
- Is it safe to use these without linking my accounts?
- Yes. None of these tools ask you to log in or connect an Instagram, YouTube, or X account, so they never touch your posting access. Most of them run in your browser rather than sending your work off to a server, which keeps them simple and quick to load.
- Which social tool should I use for which job?
- For sizing, the Instagram Image Resizer and YouTube Thumbnail Resizer fit images to each platform's dimensions. For writing, the Tweet Character Counter and Bio Character Counter keep you inside the limits, the Caption Formatter tidies spacing, and the Hashtag Generator suggests tags. To round out a profile, the Link-in-Bio QR makes a scannable code and the Engagement Rate Calculator works out your rate.
