JSON Uploader

Lets you upload .json files to the WordPress media library — handy for Lottie animations.

Version 1.0Updated Feb 2025Downloads 0

What it does 01

WordPress doesn't accept .json uploads out of the box. I built this to upload Lottie animation files, which are JSON — it simply adds the JSON MIME type so the media library takes them.

  • Enables .json uploads in the media library.
  • Made for Lottie animations, and works for any other JSON file.
  • No settings — activate it and upload.

Setup 02 · about 1 minute

  1. Install it. In WordPress go to Plugins → Add New → Upload Plugin, choose the .zip you downloaded and click Install Now.
  2. Activate it from the same screen (or later from Plugins). No settings page to configure.
  3. Upload your file. Go to Media → Add New (or any media picker) and upload your .json file like you would an image.

FAQ 03

What is it for?

Uploading Lottie animations — they're JSON files, which WordPress normally rejects.

Is there anything to configure?

No. It only adds the JSON MIME type, so you activate it and upload.

Which WordPress versions does it support?

It's listed for any WordPress version.

Is it really free?

Yes — GPL-2.0, free forever, no upsells inside the plugin.
