Short answer
Can you use Upscayl online?
You can use Upscayl online only through Upscayl Cloud, its official paid service, because the free open-source Upscayl app runs on the desktop and needs a Vulkan-compatible GPU. The other option is a browser upscaler such as Kenerate AI, whose default engine is also Real-ESRGAN, with six more engines, no install and no subscription required.

FAQ
Upscayl alternative — FAQ
7 questions
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 free credits on sign-up.
Link to this answerCan 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.
Link to this answerIs 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.
Link to this answerIs Upscayl free?
The desktop app is free and open source (AGPL-3.0). Upscayl Cloud is paid.
Link to this answerDoes 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.
Link to this answerHow is Kenerate different from Upscayl Cloud?
Kenerate has no subscription required: one-time credit packs that never expire and 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.
Link to this answerWhich 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.

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.
On this page
Upscayl is a front end for Real-ESRGAN
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].
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.
