File Previews

Frappe Drive lets you preview many common file types directly in your browser without downloading them first. This makes it easier to quickly review documents, images, videos, and text files from within Drive.

Support for additional file formats continues to expand over time, so newer releases may include previews for more file types.

Supported File Types

Frappe Drive currently supports previewing the following categories of files.

Office Documents

• PDF (application/pdf)
• Microsoft Word (.docx)
• Microsoft Excel (.xlsx)

Images

• PNG
• JPG
• GIF
• SVG
• WebP

Videos

Video files can be streamed directly from Frappe Drive. Since Drive does not currently include a video transcoding pipeline, playback depends on the codec used by the video.

Supported video formats include:

• MP4
• WebM
• QuickTime (MOV)

Supported video codecs include:

• H.264
• H.265 (platform dependent)
• AV1 (platform dependent)

Text Files

Most plain text files can be previewed directly in the browser.

• Most MIME types beginning with text/

Platform Compatibility

Some video codecs rely on browser and operating system support.

• H.264 is widely supported across modern browsers.
• H.265 support depends on the browser and operating system. For example, it is supported in Safari and on Windows and macOS versions of Chrome where the required codecs are available.
• AV1 support varies depending on browser and hardware capabilities.

Best Practices

• Use the built-in preview to quickly inspect files before downloading them.
• Encode videos using H.264 for the widest compatibility across browsers.
• Use standard Office formats such as PDF, DOCX, and XLSX for the best preview experience.
• Keep your browser updated to benefit from the latest codec support and rendering improvements.
