About
reSmush.it is a WordPress image compression plugin and HTTP API that compresses JPEG, PNG, GIF, TIF, and BMP files in the cloud. It supports image submission through the WordPress plugin, direct API calls, and third-party integrations for platforms such as Magento, Drupal, Laravel, Joomla, and Prestashop.
The API returns JSON responses with source and optimized image URLs, file sizes, percentage improvement, expiration date, and error details. The service removes EXIF data by default, supports a JPG quality parameter from 0 to 100 with a default of 92, and requires a user-agent and referer header for requests. The free API is available for personal use only, with no usage restriction except uploaded file size, and uploaded files must be under 5 MB.

Free Tier Value
This free tier is genuinely usable for small personal projects, but it is capped by a 5 MB upload limit and personal-use-only terms, so it is not equivalent to an uncapped paid plan. Because the only paid path shown is custom commercial pricing, the practical monthly value is best estimated as a low single-digit amount; about $3/month is a fair buyer-side comparison for a perpetual free API with modest limits and no sign-up friction.

- No usage restriction except uploaded file size.
