MiniPx vs Let’s Enhance — Free, Fast & Private
Let’s Enhance is a cloud upscaling service; MiniPx gives you an upscaler on your own machine and a heavier one on ours. Let’s Enhance is built for people who need many images enlarged for a shop front or a print run, so it sells batch throughput and an API. MiniPx approaches the same job from the other end: the image upscaler is free and runs in your browser, and a Pro subscriber can switch a single photo over to Cloud HD when the on-device result is not enough. Two paths for one problem, and you choose per photo rather than per subscription.
What the Cloud HD pass actually is
HAT-L at four times, with the numbers stated up front. The Cloud HD upscale accepts an input of up to 25 MB and 4 megapixels, cleans up JPEG artefacts before the model sees them, and returns up to 16× the pixels of the input — a 4 MP photo comes back at about 64 MP. On a 4 megapixel input it takes four to five minutes, which is slow enough that we tell you before you start rather than after. It draws on the HD sub-allowance: Pro includes 150 cloud runs a month on the Monthly plan, of which 10 may be HD runs, and a four-times upscale is one of them. Pricing is $3.24/month or $29/year on the launch promo ($4.99 and $39 at list, tax excluded).
Why the input is capped at 4 megapixels
Four times a 4 megapixel photo is already a 64 megapixel file. A 2000 by 2000 input comes back at 8000 by 8000, and the GPU time and memory scale with the output rather than the input. So the cap is not an artificial tier boundary; it is the point past which the job would not finish. If your source is bigger than 4 megapixels it very likely does not need upscaling at all — it needs the right resize, which the free on-device upscaler or a plain resize will do in seconds without spending a run.
What upscaling cannot do, on either service
No model recovers information the sensor never recorded. An upscaler predicts plausible detail from what is present: edges get cleaner, text gets more legible, textures get invented. That is genuinely useful for a small product shot destined for a large listing, and it is misleading for anything evidential — a licence plate, a document serial, a face in the far background. If the problem is softness and grain rather than size, the right MiniPx tool is the AI photo enhancer, which cleans blur and noise at the same dimensions, or photo restoration when the subject is a face in an old print. Reaching for an upscaler to fix a quality problem usually produces a large version of the same problem.
A print and listing workflow
Upscale once, then treat the result like any other big file. For a marketplace listing, upscale to the dimension the platform wants, check the edges of the subject at full zoom, then push the file through the image compressor so the page does not carry a 20 MB asset. For print, work backwards from the physical size: a 64 megapixel square result is about 26 inches on a side at 300 dpi, so the ceiling is generous for anything short of a poster. Crop before upscaling, never after — the crop tool is free and cropping afterwards throws away pixels you spent a run to create.
Where Let’s Enhance is the better tool, and where the file sits
Batch, automation and larger factors go to them; a single careful photo goes to us. Let’s Enhance has an API and batch processing, so it fits a catalogue pipeline that MiniPx has no answer for, and its plans reach scale factors beyond four times. MiniPx has no API, no queue and an hourly ceiling of thirty runs. On privacy: the free MiniPx upscaler never uploads anything, and the Cloud HD pass uploads that one photo for the run, processes it in the United States, and it is deleted when the run finishes, and in all cases within 24 hours, never used to train anything. Let’s Enhance is a cloud service and uploads by nature; read their policy for what they keep.
