AI Image Upscaler

Edit

Upload any image and get a sharper 2x or 4x version — face-aware, format-preserving, four upscaler models to choose from.

From small and soft to sharp and large

Four upscaler models. Identity-preserving. No invented detail.

Drop in a photo and route it through a real image-restoration model — `seedvr2-upscale` for the strongest general-purpose 2x/4x, `topaz-upscale` when faces are the subject, `aura-sr` for free fixed-4x runs, or `ideogram-upscale` when you want detail-leaning resampling. The output is the same picture, just at higher resolution — sharpened, denoised, and resolved without inventing textures, faces, or content that wasn't in the source. Pick a factor, pick a format, and download a print-ready file.

How to upscale a photo without losing the soul

Four choices that change the output dramatically.

  1. Upload the cleanest source image you have — JPG, PNG, or WebP up to 25 MB / 12 megapixels.
  2. Pick 2x for safe enlargements (smaller files, faster runs) or 4x when you genuinely need maximum sharpness.
  3. Choose an output format — JPG for small files, PNG when transparency matters, WebP for the best of both.
  4. Toggle Enhance Faces on for portraits — Topaz Upscaler runs a dedicated face restoration pass; other models ignore the setting.
  5. Switch models if the first pass disappoints — SeedVR2, Topaz, AuraSR, and Ideogram fail differently, and one will usually clear what another stumbled on.

What each upscaler is good for

Same image in; different trade-offs out.

seedvr2-upscale

Default — best general-purpose

Strongest overall accuracy and texture preservation across photos, illustrations, and screenshots. Supports both 2x and 4x cleanly.

topaz-upscale

Best for portraits & faces

Industry-standard model with a dedicated face restoration pass. Pick this for headshots, family photos, and old prints with people in them.

aura-sr

Fixed-4x, essentially free

Single-shot 4x upscaler with near-zero compute cost. Great for batch jobs, thumbnails, and asset pipelines where price beats fine control.

ideogram-upscale

Detail-leaning resample

Generative resampler tuned for posters, illustrations, and AI-generated art. Lets you bias toward detail vs. resemblance to the source.

Best for…

Photos that deserve to live larger than their original capture.

Why dedicated upscalers beat naive resampling

Bicubic stretches pixels; restoration models reconstruct them.

A naive resize (bicubic, Lanczos, the default in every image editor) interpolates between existing pixels — the result is bigger but blurrier, with no new information. Dedicated upscalers (`seedvr2-upscale`, Topaz, AuraSR, Ideogram) were trained on millions of paired low-res / high-res images and learned to recover plausible texture, edge sharpness, and fine detail that naive resampling can't reach. The failure mode is over-smoothing or texture hallucination on muddy sources — never a dropped subject, never a swapped face. Pair this tool with the AI Object Remover when you also need to clean up the source before upscaling — order matters: remove first, upscale second.

Pro tips for sharper, more honest upscales

Habits that compound across hundreds of images.

  1. Start at 2x before you commit to 4x — it's twice as fast and most reuse cases (web, prints under A4) don't actually need 4x.
  2. Toggle Enhance Faces on for portraits and pick `topaz-upscale` explicitly; other models silently ignore the setting.
  3. Pick PNG or WebP when transparency matters; JPG when file size matters more than alpha channels.
  4. Run AuraSR first on batch jobs — it's nearly free and handles 80% of cases. Only escalate to SeedVR2 / Topaz when AuraSR can't clear it.
  5. For AI-generated art, try Ideogram Upscale and dial down resemblance if you want extra fine detail invented; keep resemblance high to stay faithful to the source.
  6. Don't chain upscales — running 2x → 2x is worse than running 4x once. Pick the final factor, run once.

Image Upscaler FAQ

Which models power it?

Four dedicated upscalers — `seedvr2-upscale` (default — strongest general-purpose), `topaz-upscale` (industry-standard, face-aware), `aura-sr` (free fixed-4x), and `ideogram-upscale` (generative detail bias). All read your uploaded image directly; switch when one struggles with a particular subject.

What's the maximum input size?

25 MB and 12 megapixels per image. The provider enforces output ceilings too — a 12 MP source at 4x produces ~192 MP, which is the practical limit before files become unwieldy.

Will it invent faces or details that weren't there?

Dedicated upscalers reconstruct detail from the source — they don't hallucinate the way generative image models can. Quality drops on muddy or low-information sources, but the failure mode is over-smoothing rather than swapped subjects or invented faces.

Should I use 2x or 4x?

Default to 2x. Most prints under A4 and most web hero images don't actually need 4x. Pick 4x when you're producing posters, large prints, retina assets, or zoomable product photos — and accept that the file will be roughly 4x as large.

Does it preserve transparency?

Yes — pick PNG or WebP as the output format and any alpha channel in the source survives. JPG always returns an opaque file (which is the right choice for photos and the wrong choice for logos).

Why are my upscaled portraits soft?

Toggle Enhance Faces on AND switch the model picker to `topaz-upscale` — it's the only backend with a dedicated face restoration pass today. Other models will run successfully but ignore the toggle silently.

Can I upscale AI-generated images?

Yes — `ideogram-upscale` is tuned specifically for that use case. Drop the resemblance slider when you want extra invented detail; raise it when you want to stay faithful to the source generation.

Print-ready in seconds

Stop reshooting. Stop rescanning. Stop accepting blur.

Skip the manual sharpening passes, the third-party desktop apps, the costly Topaz licenses. AI upscaling turns small, soft, archival photos into print-ready assets in seconds — so photographers, ecommerce teams, designers, and anyone with an old photo album can finally use the images they have.
