2 Upload a file

With your button created, try uploading a file. The result will contain a file ID, which can be used at any time to download the file. You should probably save the file ID to your backend API.

File URLhttps://files.upload.io/File IDx89e18fe4x3
  • Files hosted on our ultra-fast CDN
  • Basic plans: CDN covers 100 locations worldwide
  • Pro plans: CDN covers 200+ locations worldwide

3 Transform your file

Now create a transformation through the Upload Dashboard. If you paste a transformation's slug to the end of a file URL, the result will be a transformation of that file, e.g. a resized image.
