Upscayl online: the desktop app, Upscayl Cloud, or Kenerate

Upscayl is a great free desktop upscaler — if your computer has a Vulkan GPU. Want it in the browser instead? There is the paid Upscayl Cloud, or Kenerate: the same Real-ESRGAN model family plus six more engines, no subscription, nothing to install.

Short answer

Updated

Upscayl is a free, open-source desktop app (AGPL-3.0) for Windows, macOS and Linux that needs a Vulkan-compatible GPU. To use it online you have two options: Upscayl Cloud, its official paid service (a monthly Pro plan with 300 credits), or a browser upscaler such as Kenerate AI, whose default engine is also Real-ESRGAN — 25 free credits, no install, no subscription.

Honest verdict

Kenerate or Upscayl: which should you pick?

Upscayl is a good tool. Here is when each one is the better choice.

Choose Kenerate if…

  • Your computer has no suitable GPU (most laptops with integrated graphics)
  • You are on a phone, a Chromebook or a work PC where you can't install apps
  • You upscale now and then and don't want a monthly plan
  • You also want restoration (Phota Enhance), creative detail (Clarity Pro) or exact print sizes

Choose Upscayl if…

  • You have a Vulkan GPU and upscale thousands of images — the desktop app is free and unlimited
  • You need to work offline, or keep every image on your own machine
  • You want to load your own custom NCNN models
  • You want very large cloud outputs (Upscayl Cloud Pro lists images up to 256 MP)

About Upscayl

What is Upscayl, and is there an online version?

From Upscayl's own website or repository, checked 26 September 2026. Plans change — confirm on their site.

Upscayl is a free and open-source AI image upscaler for Linux, macOS and Windows, licensed AGPL-3.0.

The README says you need a Vulkan-compatible GPU; many integrated GPUs don't work.

Its default model is Real-ESRGAN, with community models such as Remacri and UltraSharp, and you can add custom NCNN models.

Upscayl's guide says the default models natively upscale 4×; other scales are made by resizing that output. It also has Batch and Double Upscayl modes.

Upscayl Cloud is the official online service: a free trial of 10 credits (after a trial application), a monthly Pro plan with 300 credits and images up to 256 MP, and Business on request.

Switching

How do I switch from Upscayl to Kenerate?

  1. Step 1: Open the Kenerate upscaler

    Go to kenerateai.com/app/tool/image-upscale in any browser — nothing to download, no GPU needed.

  2. Step 2: Pick Real-ESRGAN

    It is the default engine and the same model family Upscayl uses by default.

  3. Step 3: Try the other engines on hard images

    Image Upscaler for 4K/8K, Clarity Pro for extra detail, Phota Enhance for old or blurry photos.

  4. Step 4: Batch the rest

    For a folder of photos, use Batch edit in Edit Studio — up to 20 at a time.

Test before you commit

Run the same 3–5 images (a face, text, a texture, a low-res screenshot) through both tools and compare at 100% zoom.

In depth

Upscayl and Real-ESRGAN, explained

What Upscayl runs under the hood, and why the same model family behaves the same in a browser — with sources.

Upscayl is a front end for Real-ESRGAN

Upscayl's README says it uses Real-ESRGAN and Vulkan to upscale on your GPU [1]; its guide notes the default models upscale 4× natively and other scales are made by resizing that output [2].

What Real-ESRGAN is good at

Real-ESRGAN (Wang et al., 2021) was trained on synthetic real-world damage — blur, noise, resizing and JPEG, applied twice — so it handles phone photos, screenshots and reposts well [3]. It is open source under BSD-3-Clause, with a separate lighter model for anime [4]. Kenerate's default engine is Real-ESRGAN, so on the same image the two give similar results; the difference is where it runs and what else is available.

When a different engine is better

Real-ESRGAN is a GAN model tuned for sharpness. For faces in old photos a restoration model is better; for art where you want new texture, a creative diffusion-style upscaler is. The perception–distortion trade-off means no single model is best at both [5].

FAQ

Upscayl alternative — FAQ

7 questions

Still stuck?

A real person answers — usually within a day.

Email usTry it free
01

Is there an Upscayl online version?

Yes — Upscayl Cloud is Upscayl's official paid online service (a monthly Pro plan with 300 credits, and a 10-credit free trial after an application). The free Upscayl app itself is desktop-only. If you want a browser upscaler without a subscription, Kenerate runs Real-ESRGAN online, with 25 free credits on sign-up.

02

Can I use Upscayl without a GPU?

The desktop app needs a Vulkan-compatible GPU and many integrated GPUs won't work. Without one, use Upscayl Cloud or an online upscaler such as Kenerate, which runs on our servers.

03

Is Kenerate the same as Upscayl?

No. Kenerate is a separate product. Its default engine is Real-ESRGAN — the same model family Upscayl uses by default — and it adds six other engines, from 2K/4K/8K output to photo restoration.

04

Is Upscayl free?

The desktop app is free and open source (AGPL-3.0). Upscayl Cloud is paid.

05

Does Upscayl work on Mac?

Yes, Upscayl lists macOS 12 and later, as well as Windows 10+ and Linux. Kenerate works in any browser on any system.

06

How is Kenerate different from Upscayl Cloud?

Kenerate has no subscription: one-time credit packs that never expire and 25 free credits on sign-up, with seven engines including 4K/8K output and photo restoration. Upscayl Cloud is a monthly plan; Pro includes 300 credits and images up to 256 MP.

07

Which gives better quality?

With the same Real-ESRGAN model the results are similar. Kenerate's extra engines matter for faces, old photos and print sizes; Upscayl's custom models matter if you have a favourite community model.

Every pixel, rebuilt. Up to 128 MP.
