Rich previews¶

Preview files directly in the browser without downloading. No extra plugins or apps required. The backend serves content with appropriate MIME types; the frontend chooses the renderer based on file category.

Supported formats¶

Category	Extensions
Images	`.jpg`, `.jpeg`, `.png`, `.gif`, `.webp`, `.svg`, `.bmp`, `.ico`, `.tiff`, `.tif`, `.avif`
Video	`.mp4`, `.webm`, `.ogg`, `.ogv`, `.mov`

How it works¶

Binary files (images, video, audio, PDF) — Served with the correct Content-Type; the browser or frontend component handles display.
Text-based files — Rendered as plain text, or with syntax highlighting for code. Markdown, JSON, and CSV get dedicated preview components.
Size limit — Text previews are capped at 512 KB. Larger files fall back to download.

Signed URLs¶

For sharing previews without exposing your session, use signed URLs. Generate a short-lived link for preview or download; the link works without a JWT.
