Upload API provides several ways to upload files to Uploadcare servers in a secure and reliable way.

For high-level integrations and SDKs, see available libraries.

File storage

Every uploaded file is temporary and will be deleted within 24 hours unless stored. To make a file permanent:

  • On upload via the UPLOADCARE_STORE flag
  • Use store or copy via the REST API

Note: UPLOADCARE_STORE=auto delegates the storage decision to the project’s auto-store setting, which is enabled by default.

File delivery

Once uploaded, files are available via the CDN. The CDN supports on-the-fly image processing and proxying.
