# Free social media tools from Postify

> Free social media tools and reference tables: a character counter, a video and image checker and image sizes, every limit sourced and dated.

## Tools

- [Social media character counter](https://usepostify.com/tools/character-counter): Paste a post and see how many characters it uses against each network's limit, counted the way Postify's composer counts.
- [Will it post? Video and image checker](https://usepostify.com/tools/media-validator): Drop a video or an image and see which networks accept it, which published rule it breaks and how to fix it. The file never leaves your browser.

## Reference tables

- [Social media image sizes](https://usepostify.com/social-media-image-sizes): The image and video sizes each network recommends, quoted from its own pages, with the date each was checked.
