SFW

What Does SFW Mean?

SFW means "Safe for Work" and "Software."

Safe for Work

The abbreviation SFW is typically placed in the title of a message to indicate that the message can be opened safely in a work environment (i.e., it is "Safe For Work"). SFW usually indicates that the message content will not cause offense to the recipient's boss or work colleagues. SFW does not mean that the message is work-related. Therefore, such communications should not normally be opened in the presence of colleagues or supervisors, except during breaks from work (e.g., during lunch or coffee breaks).

SFW contrasts with the following terms:

• NSFW (Not safe for work).
• NSFA (Not safe for anyone).
• NWS (Not work safe).

Beware "Seemingly SFW." As the term SFW has grown more popular, it has developed a secondary, more nuanced meaning, which is best described as "seemingly innocent." This typically involves a picture of an adult nature that has been edited to replace the adult content with innocent content, as in this picture:

Software

Particularly amongst specialists in IT, SFW is used with the meaning "Software" (i.e., those elements of data or computer instructions that tell a computer system how to work, as opposed to HW (Harware), which are the elements from which the physical system is built).
