How to open .FBS files on iOS

To open .FBS files on iOS, iOS may not preview .FBS (FastBid Sheet) files in Files/Quick Look; share or transfer the file to a desktop system that has FastBid-related software available.

Step-by-step instructions

  1. iOS may not preview .FBS (FastBid Sheet) files in Files/Quick Look; share or transfer the file to a desktop system that has FastBid-related software available.

Alternative methods

  • Open .FBS in a browser-based viewer if desktop apps fail.
  • Try opening .FBS on iOS with a secondary app to rule out app-specific issues.
  • Convert .FBS only with trusted tools when direct opening is not possible.

Common issues

The file won’t open in standard image viewers

Many .FBS files are FastBid Sheet images and may be TIFF-based/proprietary, so common photo apps may not decode them.

  1. Open the file using the FastBid software (or the application used to create/export it).
  2. If you don’t have the software, ask the sender for a more widely supported export (for example, TIFF/PDF) from the originating tool.

Wrong program opens it (or Windows asks what to use)

Your system may not have an association for image/vnd.fastbidsheet/.fbs, or the association was set incorrectly.

  1. On Windows, right-click → Open with → choose the correct FastBid-related application and set it as default if appropriate.
  2. If you’re unsure what it is, confirm the file’s source; .fbs can represent unrelated formats.

The .FBS file is not actually a FastBid Sheet image

The .fbs extension is reported to be used by other unrelated file types; in that case, image tools will fail.

  1. Confirm where the file came from and what application generated it.
  2. If it’s not from a FastBid/plan-sheet workflow, search within that originating application for an import/open function rather than treating it as an image.

File appears corrupted or incomplete

If the download/transfer was interrupted, the file may be truncated and unreadable by parsers.

  1. Re-download or re-copy the file from the original source (avoid email systems that may alter attachments).
  2. Compare file size with the sender’s copy and try opening again in the original creating application.

Security note

Treat .FBS files as potentially untrusted input to image parsers: even though it’s an image MIME type (image/vnd.fastbidsheet), malformed image data can still trigger vulnerabilities in viewers/converters.
