Trouble downloading or previewing files

Last updated: July 15, 2026

A missing preview or a download that won't start is almost always one of three things: your browser blocking part of a multi-file download, a preview Brault hasn't finished generating yet, or a large download that got interrupted partway through. The checks below cover all three, fastest first.

Downloads don't start, or only one of several files comes through

Browsers ask permission before letting a site download more than one file at once. If you missed that prompt, or said no to it, the first file saves and the rest stop without any error message.

  1. Look in your browser's address bar for a blocked-download icon and choose to allow downloads from brault.app.
  2. Retry the download. Most browsers show the multi-file prompt again once you're back on the page.
  3. If downloads still don't start, turn off ad blockers or privacy extensions for brault.app, or try a different browser. Extensions that filter network requests can block a download without showing any warning.

The preview or thumbnail never appears

  1. Give it a few minutes first. A newly uploaded file shows Your file is being processed. It will be available soon. in the file drawer while Brault generates its preview and thumbnail. Larger files take longer.
  2. Check the format if the spinner clears but no image shows up. Some file types don't get a preview at all: Brault still stores the file and lets you download it, it just skips the preview and thumbnail step for formats outside its list. See Supported file formats in Brault for exactly which formats get one.
  3. If a file sits on "processing" for a long time and it's a format Brault does support, that's not expected. Contact us using the details below instead of waiting it out.

A large download stops before it finishes

  1. Click the download link again. Most browsers resume or restart an interrupted download on their own.
  2. Check your free disk space. Video and RAW files are the usual reason a download fills the disk partway through; see Supported file formats in Brault for size limits by type.
  3. Rule out a network drop. Switching networks mid-download, a VPN, or a corporate proxy can all cut a download short, the same as they do with uploads. My upload is stuck covers the same network checks; they apply to downloads too.

If none of this worked

Contact us from the support form and include the file name, whether you were downloading or previewing it, and roughly when it happened. That's enough for us to trace it in the logs. We usually reply within one business day.
