How to Stop Microsoft Copilot from Blurring Faces in Uploaded Images

- Product
- Microsoft Copilot
- Device & OS
- not provided
- Scenario
- Uploading personal or portrait images to Copilot for AI analysis and editing.
- Observed behavior
- Copilot rejects the original 'PNF' file. When converted to JPG, the AI successfully processes the image but applies a blurred square over human faces due to built-in safety filters.
Ensure your image is in a standard format natively supported by web browsers, and note that Microsoft implements strict server-side privacy policies for facial recognition that cannot be bypassed.
Troubleshoot the Unsupported File Format
Fix file extension issues and use native image formats to ensure Microsoft Copilot accepts your upload.
The 'PNF' file format mentioned is highly uncommon for images and is likely a typo for 'PNG'. Converting files through third-party applications can sometimes alter metadata or degrade image quality. Using natively supported formats ensures smooth uploads.
Locate your original file on your device. If the extension reads '.pnf', right-click the file, select 'Rename', and change the extension to '.png'.
Attempt to upload a native .JPG, .JPEG, or .PNG file directly from your camera or standard photo editor, skipping any heavy format converters.

Microsoft implements strict AI privacy and safety guidelines. Copilot automatically obscures human faces to prevent unauthorized facial recognition, protect user identity, and comply with global privacy regulations.
Can I disable the face blurring feature in Copilot?
No, the face blurring is a server-side safety mechanism enforced by Microsoft. There is no toggle or setting available to disable it in the user interface.
What image formats can I upload to Microsoft Copilot?
Copilot typically supports standard web-friendly image formats such as JPEG, PNG, and WebP. If you have an unsupported format, converting it to one of these standard types will allow the upload.
What is a PNF file and why won't it upload?
A 'PNF' file is usually a system configuration file (Precompiled Setup Information), which Copilot does not accept. In the context of images, it is most likely a typo for 'PNG'. Try manually renaming the file extension to .png.
