Preview More File Types in the Media Library

The Media Library now supports in-browser previews for more file types, helping you inspect files without downloading them first.

Supported previews

You can preview these file types directly from the existing preview modal:

  • PDF files: Browse pages, zoom in and out, jump to specific pages, and select text.
  • Word documents (.docx): View document formatting, including pagination, headers, and footers.
  • Excel and CSV files: Open spreadsheets with worksheet tabs and familiar column headers.
  • Audio files: Play supported audio formats in the browser, including MP3, WAV, OGG, and M4A.
  • 3D models: Interactively view supported 3D files with controls for rotation, wireframe mode, and camera reset.
  • Text and code files: Preview JSON, CSS, plain text, and other supported text-based files with syntax highlighting.

How it works

  1. Select a file in the Media Library, or choose Preview from the right-click menu.
  2. SMBcrm opens the correct viewer automatically based on the file type.

Preview limits

Preview size limits apply:

  • PDF: up to 50 MB
  • Word: up to 15 MB
  • Excel and CSV: up to 15 MB
  • 3D models: up to 50 MB
  • Text files: up to 5 MB
  • Audio files: up to 100 MB

Files that exceed these limits display a Too Large to Preview message with an option to download the file instead.

Spreadsheet previews are limited to 1,000 rows by 100 columns per worksheet to maintain performance. If a file exceeds those limits, a notice appears and the full file can still be downloaded.

Unsupported file types, such as PowerPoint files, ZIP archives, font files, and legacy Word documents, display an improved Preview Not Available message when browser preview is not supported.
