What the Upscaler does

Upscaler enlarges your image and fixes common defects (softness, minor noise, low micro-detail). You can prioritize speed & price, maximum realism, or face preservation so identity never drifts. Every result can be sent on to Face Swap, Carousel, Video, or straight to Publishing.

Modes

Basic — Fast, detailed, may change face

  • Enlarges, cleans up, and adds detail quickly.
  • Cheapest option; great for drafts, carousels, and bulk batches.
  • Face may change slightly (no face tracking).
  • 4MP and 8MP variants available.
  • Use when: you need speed and don’t care if the face shifts a bit.
  • Avoid if: identity must remain identical.

Basic Safe Face — Fast, detailed, face unchanged

  • Same speed class as Basic, but tracks the face and keeps it intact.
  • 4MP and 8MP variants available.
  • Use when: you want quick upscales and must preserve identity.
  • Avoid if: you want the very highest realism (see Premium).

Premium Realism — High detail & realism, may change face

  • Best overall fidelity: richer skin, fabric, edges, and lighting.
  • Slower and more expensive than Basic. No face tracking, so the face can change.
  • 4MP and 8MP variants available.
  • Use when: you want the prettiest possible image, and identity isn’t critical.
  • Avoid if: the face must be identical → use Premium Safe Face.

Premium Safe Face — High detail & realism, face unchanged

  • Premium quality with face preservation.
  • Slower and pricier than Basic Safe Face.
  • 4MP and 8MP variants available.
  • Use when: you need top-tier realism and zero face drift.
  • Avoid if: you only need quick, social-ready results.

Sharp Keep — Sharper image, minimal changes

  • Boosts crispness with near-zero alterations everywhere (not just the face).
  • 8MP only.
  • Use when: product shots, e-commerce, labels, fabrics — nothing should change, just look sharper.
  • Avoid if: you want added texture or heavy restoration.

Textured Boost — Adds realistic texture & depth

  • Enhances pores, hair, fabric, and surfaces for a natural, tactile feel.
  • 8MP only.
  • Use when: beauty/fashion, portraits, or scenes that feel too “plastic” after generation.
  • Avoid if: the brief requires minimal change (then use Sharp Keep).

4MP vs 8MP — which output?

  • 4MP: faster, cheaper, perfect for most social feed posts and quick approval loops.
  • 8MP: slower, larger file, better for cropping, hero images, printing, or thumbnails/covers that must stay crisp.

Recommended choices by scenario

  • Lock the same face, publish fast: Basic Safe Face (4MP or 8MP)
  • Top quality and identity preserved: Premium Safe Face (8MP)
  • Best look, identity not critical: Premium Realism (8MP)
  • E-com & product accuracy: Sharp Keep (8MP)
  • Portraits that feel flat/plastic: Textured Boost (8MP)

Power option: Upscale + Face Swap (combined flow)

If you already know which face you’ll use, the Upscale + Face Swap flow upscales and locks the face in one pass. It’s our near-best default for most pipelines because you get:

  • Finished, publish-ready images with the correct identity,
  • Fewer clicks and less back-and-forth between tools,
  • Consistent looks across a whole batch.

Pro tips

  • Identity matters? Always choose a Safe Face mode or the combined Upscale + Face Swap flow.
  • Need strict accuracy? Use Sharp Keep to avoid altering patterns, labels, or product geometry.
  • Batch wisely: Upscale selects first; don’t upscale everything — save credits for winners.

FAQ

Will upscaling change the face?

  • Basic and Premium Realism can change faces.
  • Basic Safe Face and Premium Safe Face keep the face unchanged.
  • Sharp Keep barely changes anything (face included).

Which mode is the best overall? There’s no single “best,” but for most pro workflows: Premium Safe Face (8MP) for finals, Basic Safe Face (4MP) for fast previews, and Textured when portraits need more life.

Can I run it on results from any tool? Yes — send images from Face Gen, Prompt, Reference, PhotoShoot, Carousel, or uploads.
