Unsupported formats

Hard limit: HEIC / HEIF images. HEIC is Apple's default photo format. It is not supported for image editing. Convert to JPEG or PNG first. On iPhone: open the photo, tap Share then Save as JPEG, or use Files to export as JPG.

Hard limit: Video files. Not supported in any format.

Hard limit: Audio files. Not supported for upload. Voice input (speech-to-text) is supported via the microphone button.

Hard limit: .doc (legacy Word). Legacy .doc format is not supported. Save as .docx first.

Image editing limitations

• The edit model (gpt-image-1) changes backgrounds and scene elements but cannot guarantee exact facial preservation. Faces may shift slightly.
• HEIC files must be converted before editing.
• Very complex edits ("put this person in a completely different scene") work better than subtle edits ("adjust the lighting slightly").
