Reloops is built for creative review files first. The web upload picker is configured for common image, video, PDF, audio, and text/data files. Larger uploads use the same Supabase upload-b2 flow behind the scenes and can use multipart upload up to 5GB per file.

​
Quick reference

Browser file pickers use MIME types, so some extensions are accepted because the browser reports a supported MIME type. For example, .jpg and .jpeg both map to image/jpeg.

​
Upload limits

  • The maximum file size is 5GB per file.
  • The web app automatically uses multipart upload for large files.
  • Upload batches can include multiple files and folders.
  • Folder upload preserves the folder structure inside the project.
  • Empty files and files with missing names are skipped.

​
Review support by type

Different file types get different review surfaces.

​
Thumbnail and AI metadata behavior

Reloops generates the best preview it can for supported review formats.
  • Images, videos, and PDFs can receive thumbnails.
  • Very large files may finish uploading before thumbnail processing completes.
  • Files without a dedicated preview can still be organized, tagged, shared, and downloaded.
  • AI metadata is best supported for images, videos, audio, text, documents, and design-like formats.

​
API and Supabase upload behavior

The web app uploads through the Supabase Edge Function upload-b2. That upload API:
  • requires a valid user session or API key,
  • checks workspace access before signing or completing uploads,
  • stores the file in object storage,
  • records the provided contentType as the asset mime_type,
  • enforces 5GB as the multipart upload maximum.
The API does not maintain a separate extension allowlist. If you upload a file type outside the web picker through an API path, Reloops may store it as a generic downloadable asset, but preview, thumbnail, compare, and AI metadata support can be limited.

​
Not supported for review or AI processing

These file types are not part of the supported web upload picker and are not processed by the AI metadata worker:
If a file uploads but does not show a rich preview, keep using the asset card for status, assignment, metadata, comments, sharing, and download.
