Step 1
Choose the cleanest original
Use the highest-quality version you can access, rather than a screenshot of a compressed preview. Look for intact edges, readable shapes, and minimal compression blocks. An upscaler can propose missing texture, but it cannot verify what a blurred sign actually said or restore a face with certainty. Keep the untouched original beside your working copy.
- Prefer an original export over a social-media download.
- Identify text, faces, logos, and product features that must not change.
