Find the best available input
Check whether the file was saved from a thumbnail, forwarded through messaging or captured from a screen. A downloaded original is usually a better starting point than a screenshot of that download. Ask the owner for the source file when you have an appropriate reason and permission.
Change one variable at a time
- Search the existing file as it is.
- Try a crop that removes unrelated interface elements.
- Search a larger original if one becomes available.
- Compare source pages rather than treating a sharper thumbnail as a better match.
For example, repeated blocks around lettering are compression artefacts. Increasing contrast can emphasise those blocks instead of revealing the original letters. Text search using a clearly readable fragment may be more productive than repeatedly altering the file.
Avoid false confidence
Do not treat AI-restored facial details or invented text as evidence. A useful match should be supported by surviving features such as composition, clothing or a distinctive object. If those features are missing, label the result tentative and keep the original low-quality file with your notes.
