Does this automatically upscale to 4K?

That depends on the model and resolution controls. This is not a dedicated exact upscaler.

Can it read a blurred label or number?

Not reliably: characters may be invented. Use another source to verify a document or number.

How is this different from old-photo restoration?

This guide covers lighting and noise. Scratches and creases are covered in old-photo restoration.

Improve photo quality

Brighten a dark photo or reduce noise. Compare with the source: stronger sharpening can conceal invented details.

Getting started

Find the original, not a messaging screenshot.
Choose brightness or noise reduction.
Upload the photo and paste the prompt.
Compare texture and lettering at equal scale.

Prompts

Copy a suitable prompt and replace any bracketed instructions.

Brighten without changing the scene

Gently balance brightness in my photo: make dark areas easier to see while retaining highlight detail. Preserve people, objects, lettering, colours and composition. Add no details, smooth no faces and do not turn the photo into a stylized illustration.

Check: Inspect windows, highlights and white clothes for lost bright-area detail.

Reduce noise conservatively

Prepare a cleaner version of the uploaded photo with moderate noise reduction. Preserve natural skin and material texture, facial features, fabric patterns and all readable lettering. Do not sharpen indistinct regions into invented detail or reconstruct hidden information. Keep viewpoint and object scale.

Check: Check skin and fabric: a plastic-looking texture calls for less editing.

More pixels do not mean more detail

Output size depends on the model’s controls. Writing “4K” does not guarantee dimensions or recovery of unreadable text.

When to use another photo

For an exact number, face or label, find a clearer source. Repeated generation does not verify a guess.
