The minimum-size setting helps prevent tiny thumbnails and interface assets from dominating Similar Photos results.
Change the minimum
Open Settings → Scanning → Similar Photos. The default is 40 KB. Values automatically display in KB or MB according to size.
Run a new scan after changing the setting.
Lower the value
Lower values include more thumbnails, previews, icons, and compressed images. Use them for a small, intentional collection rather than a broad disk scan.
Raise the value
Higher values focus on larger photos and reduce comparison work, but can omit small exported or messaging images.
File size is not quality
Compression, format, dimensions, edits, and metadata all affect size. A smaller photo is not necessarily worse or unnecessary.
Restore default
Choose Default to return to 40 KB. If photos remain missing, verify format support, local availability, folder access, and ignore rules.
