Gigapixel AI Review: Is The Image Upscaler Still Worth It in 2026?
No credit card. A real, working install. But there's a catch most landing pages bury — and once you know what it actually is, it changes how you should test this thing before paying anything.
Gigapixel AI Review: The Verdict at a Glance
The upscaling itself is genuinely very good — Gigapixel was the first commercial AI upscaler and it still reconstructs detail on degraded sources better than almost anything else. Nine specialised models, local processing, and a free trial that gives you the whole toolset with no card required.
What drags the score down isn't the software, it's everything around it. The in-app trial messaging overstates how locked you are, post-trial pricing has changed repeatedly and varies between sources, and local rendering demands a capable GPU. Great tool; confusing purchase.

What the Trial Actually Gates
This is the single most useful thing to know before you download, and the in-app wording actively obscures it.
Almost the entire app is unlocked in trial mode. Only saving is blocked.
The trial pop-up's phrasing reads as though most of the app is locked, and multiple user reports on the official Topaz Community forum describe exactly this confusion. In practice you get every model, every setting, and full-resolution preview. The only genuinely gated action is saving your work. Knowing that in advance means you can run a proper evaluation — process ten of your own difficult images and judge the results honestly — rather than assuming the trial is too limited to be worth the download.
The standard desktop trial prompts a purchase when you click Export. But some bundled or promotional install paths instead allow a fixed number of free exports, commonly cited as around ten images. Because both paths are in circulation, test an export early rather than processing thirty images first and discovering you can't keep any of them.
What Gigapixel AI Actually Is
Gigapixel AI was the first commercially available AI image upscaler, launched by Topaz Labs in 2019 — well before the current wave of generative tools. It enlarges images up to 6× while reconstructing detail that traditional interpolation simply blurs, using nine specialised models trained for different source types: Standard, High Fidelity, Low Res, Recover, Redefine, Face Recovery and others.
The important architectural detail: processing runs locally on your own machine by default. For photographers handling client work, that matters — no upload, no third-party storage, no ambiguity about who has your files. Cloud rendering is available as an alternative for people without capable GPUs, but it draws on account cloud credits, including during a trial.
Gigapixel is also sold separately from Topaz Photo AI, which bundles upscaling with denoise and sharpen. If you need noise reduction as well as enlargement, our Topaz Photo AI review covers the fuller product and its own pricing shift.
How to Try Gigapixel AI Free, Properly
Five steps, no payment details at any point. The last one is the one most guides omit.
Download from the official Topaz Labs page
Go direct to topazlabs.com rather than a mirror or a "free version" site. Pirated and resold installers are a common scam vector in this category — and there's no reason to risk it, since the official download needs no payment information.💡 If a site offers "Gigapixel AI free full version," close the tab. The real trial is already free.
Install and create a free Topaz account
You're prompted for an email address and password only — no card details at this stage. The same account manages your licence later if you decide to buy.
Dismiss the "no licence found" prompt
After logging in, the app reports that no licence is attached to your account. Close the dialog and it opens in Trial mode — shown as a small label in the top-right corner. Nothing has gone wrong; this is the expected path.
Drag in a real image and run any of the nine models
Trial mode gives full access to every model, and you can preview results at full resolution side by side against the original. Use your own difficult files, not a demo photo.💡 Old scans, low-res portraits and heavy crops are where Gigapixel is most likely to impress. Sharp 4K originals are where it's least likely to.
Test an export early to learn which limit applies
Click Export on your first processed image. If it prompts a purchase, you're on the standard trial and everything after this is preview-only. If it saves, you likely have a bundled install with a fixed export allowance — plan accordingly rather than burning it on test shots.
Where the Upscaling Earns Its Keep
The honest framing is that Gigapixel's value depends almost entirely on how degraded your source is. The AI reconstructs missing detail — so the more detail is genuinely missing, the more visible the gain.
Where it shines: old scanned family photographs, faded prints, low-resolution portraits, compressed web images, and heavy high-ISO crops. On this material the improvement is large and immediately obvious — faces recover structure, text becomes legible, texture returns where there was mush. The Face Recovery model in particular does real work on small-in-frame subjects.
Where the gains narrow sharply: already-sharp 4K originals and natively high-resolution AI-generated images. There's simply less missing information to reconstruct, so you're paying for a marginal improvement. This is exactly the case the free trial exists to let you test — and exactly the case where a free alternative may be sufficient.
At 2× the results are consistently excellent. At 4× they remain good. At 6× artefacts become visible under close inspection — realistic for any current AI upscaler rather than a specific failing.
The gains are largest where the source is genuinely degraded. On an already-sharp file, you're paying for a marginal improvement — which is why testing your own worst image matters more than any review's sample gallery.
Hardware & Speed: The Practical Constraint
Local rendering is Gigapixel's privacy advantage and its main practical hurdle. Topaz cites roughly 4GB of VRAM as a baseline, and the newer generative-style models inside the app want considerably more than that.
On a weak or integrated GPU, a single 4K upscale can take several minutes rather than seconds — slow enough that people frequently assume the software is broken when it's simply under-resourced. If that's your situation, cloud rendering removes the hardware requirement but consumes account cloud credits, including on a trial, so it isn't an unlimited workaround.
An earlier version of this page listed 8GB+ VRAM in the hero strip while stating 4GB+ in the body and sidebar. The correct baseline figure Topaz publishes is around 4GB; 8GB is a comfortable-performance recommendation, not a minimum. We've standardised on 4GB as the baseline throughout, with the caveat that heavier models genuinely want more.
Pricing After the Trial: Genuinely Unclear
This is the weakest part of the Gigapixel proposition, and it's worth being blunt about it: what you'll pay depends on which pricing structure is live when you buy, and published figures genuinely disagree.
| Route | Reported price | Notes |
|---|---|---|
| Free trial | $0 | All 9 models · full-res preview · export gated · no card required |
| Legacy perpetual licence | ~$99 | Still appears in some Topaz sales documentation; perpetual licensing was discontinued in late 2025 |
| Standalone subscription | ~$12–50/mo, varies | Cited across a wide range depending on tier and source |
| Topaz Studio bundle | ~$399/yr | Covers multiple Topaz tools — better value if you need more than upscaling |
Figures as reported across sources. Topaz has revised this structure more than once since 2025 — verify on the official pricing page.
You'll see the claim that Gigapixel costs "$99.99 for a perpetual licence (or roughly $12.49/month)." Those aren't equivalent: $99.99 ÷ 12 = $8.33/month, and $12.49 × 12 = $149.88. The only span where $12.49/month totals $99.99 is eight months. We've removed the equivalence rather than repeat it — treat the perpetual figure and the subscription figure as two separate things, because that's what they are.
Related, and worth noting if you've read our other Topaz coverage: the ~$99 figure refers to Gigapixel standalone, while Topaz Photo AI's former one-time price was around $199. Both numbers are correct — they describe different products.
Gigapixel AI Review Scorecard
Seven dimensions scored out of 5. Mean: 3.8/5 — matching our headline verdict. Earlier versions of this page carried three overlapping score blocks with conflicting labels and values; this is now the single set.
The shape is unusually lopsided: the top four scores are all about the software, and the bottom three are all about how it's sold. That's the review in one chart.
Free & Paid Alternatives
Gigapixel no longer competes alone. Several free tools now get close enough that testing them alongside the trial is worth the hour.
| Tool | Price | Quality vs Gigapixel | Best for |
|---|---|---|---|
| Gigapixel AI | see pricing above | Benchmark | Degraded sources, face recovery, 4×+ print |
| Upscayl | Free | Very close at 2×; gap reopens at 4×+ | Web, social, most everyday upscaling |
| Real-ESRGAN (CLI) | Free | Same underlying model as Upscayl | Large unattended batches |
| SammaPix | Free | Good at 2×/4×, browser-based | One-off jobs with no install |
| Topaz Photo AI | ~$17–21/mo | Same upscaling + denoise & sharpen | If you also need noise reduction |
The honest headline: Upscayl is free, open source, processes locally, and gets remarkably close to Gigapixel at 2× — which covers the overwhelming majority of real upscaling needs. Gigapixel keeps a real edge at 4× and above on the finest details, and its Face Recovery model has no free equivalent. Our Topaz Photo AI alternatives guide runs the full comparison including denoise-focused options.
Pros & Cons
- Genuinely free trial — no credit card at any point.
- All 9 models available in trial, not a cut-down demo.
- Full-resolution preview so you can judge quality properly.
- Local processing by default — client files never leave your machine.
- Outstanding on degraded sources — old scans, low-res portraits, heavy crops.
- Face Recovery model has no real free equivalent.
- Up to 6× enlargement with genuine detail reconstruction.
- Trial messaging is misleading — "unlock all features" implies far more is locked than is.
- Export is blocked on the standard trial — you can't keep anything.
- Post-trial pricing is genuinely unclear and has changed repeatedly since 2025.
- Two different trial paths in circulation with no way to tell in advance.
- Needs a capable GPU — minutes not seconds on weak hardware.
- Marginal gains on already-sharp sources — the value case narrows fast.
- Free rivals close the gap at 2×, where most people actually work.
Gigapixel AI is a very good upscaler wrapped in a confusing commercial story. The software does what it claims, particularly on genuinely degraded material where the detail reconstruction is still class-leading and the Face Recovery model has no free match. The free trial is honest in the way that counts — no card, every model, full-resolution preview — even though the in-app copy oversells how locked you are.
The reasons to hesitate are all commercial rather than technical. Post-trial pricing is genuinely murky, two different trial paths are in circulation, and free tools like Upscayl now get close enough at 2× that many people never need to pay. Our recommendation: install the trial, run ten of your own worst images through it, and test an export early. If the improvement on your actual files is dramatic, the purchase decision is easy. If it's marginal — which it often is on already-sharp sources — try Upscayl before spending anything.
Gigapixel AI Review — Common Questions
Is the Gigapixel AI free trial really free, with no credit card?
Yes. You download directly from Topaz Labs, create a free account with just an email and password, and the app opens in Trial mode automatically. No payment information is requested at any point during install or setup. For a category where "free trial" often means a watered-down demo, this is a genuinely fair offer: every AI model and full-resolution preview is available immediately.
Can I export or save images during the free trial?
Generally no. The standard desktop trial lets you process and preview full-resolution results, but clicking Export prompts a licence purchase before the file saves. Some bundled or promotional install paths instead cap you at a fixed number of free exports, commonly cited as ten images. Because two paths exist, test an export early so you know which limit applies to your install.
What does the trial pop-up actually mean by "unlock all features"?
Less than it sounds. Multiple user reports on the official Topaz Community forum describe the confusion this causes, because the wording reads as though most of the app is locked. In practice almost the entire feature set is available — every model, every setting, full-resolution preview. The only thing genuinely gated is saving your work. Knowing that in advance stops you assuming the trial is more limited than it is.
How much does Gigapixel AI cost after the trial?
It depends which pricing structure is active when you buy, and sources genuinely disagree. A legacy perpetual licence around $99 still appears in some Topaz sales documentation, standalone subscriptions are cited roughly in the $12–50/month range depending on tier, and the Topaz Studio bundle runs around $399/year. Topaz has changed this more than once since 2025, so verify on the official pricing page rather than trusting any third-party figure.
What source images benefit most from Gigapixel?
Genuinely low-resolution or degraded material. Old scanned family photos, low-resolution portraits, compressed web images and high-ISO wildlife crops all show large perceived improvements. Already-sharp 4K sources and natively high-resolution AI-generated images show far smaller gains, because there's less missing detail to reconstruct. Run your own worst image through the trial preview — that's exactly the question the free trial exists to answer.
Do I need a powerful GPU to use Gigapixel AI?
For local rendering, a reasonably capable one. Topaz cites around 4GB of VRAM as a baseline, and the newer generative-style models want considerably more. On a weak or integrated GPU a single 4K upscale can take several minutes rather than seconds — slow enough that people assume the software is broken when it's simply under-resourced. Cloud rendering avoids the hardware requirement but draws on your account's cloud credits, including during a trial.
What is the closest free alternative to Gigapixel AI?
Upscayl, a free open-source desktop app built on the Real-ESRGAN model, is the closest free match and holds up well against Gigapixel specifically at 2× upscaling. The gap reopens somewhat at 4× and above, where Gigapixel still edges ahead on the finest details like individual hair strands and small text. SammaPix offers a no-install browser option for quick one-off jobs, and Real-ESRGAN via command line suits large unattended batches.

The Upscayl link earns us nothing, and it's here because for 2× upscaling it's genuinely sufficient for most readers — which is the honest answer even though it costs us the click.
