Topaz Gigapixel alternative: a browser AI upscaler vs the desktop app

Gigapixel is a desktop application from Topaz Labs for Windows 10/11 and macOS 12–15. It runs as a standalone program or as a plugin for Photoshop and Lightroom Classic, and the product page advertises both local GPU rendering and cloud rendering. The headline claim is upscaling “almost any image 6x”; the same page’s FAQ separately says up to 16 times, which is a reminder to treat any single multiplier as a marketing claim until you test your own file.

It is sold by subscription only. The pricing page lists Gigapixel at $29 per month, $19 per month on a 12-month commitment billed monthly, or $149 per year, with unlimited local and cloud-image rendering, two concurrent jobs and limited commercial rights. The Pro licence is $54 per month with an annual commitment or $499 per year and adds full commercial rights and seat management. No one-time purchase is listed.

This site runs the same class of models on a cloud worker and returns the result to the browser tab. There is nothing to install and no GPU to own: the upload is limited to 10 MB and one image is processed per run. A guest can try one upscale without an account; after that, the free plan grants 25 credits per daily login, which covers one standard SeedVR2 image per day.

The picker exposes several models, including a Topaz image model at 100 credits, SeedVR2 at 25, Crystal at 40, Recraft Crisp at 20 and Ideogram at 80. Scale choices are 2x, 4x and 8x, and the credit cost is shown before the job runs. Paid plans start at $12.90 per month for 1,000 credits, and one-time packs start at $12.90 for 500 credits. A failed job refunds its credits.

Gigapixel’s annual plan is $149 per year, which works out to about $12.42 per month. For that you get unlimited local and cloud-image rendering under the licence, a very different bargain from paying per job: if you upscale 400 images in a year, the desktop licence is far cheaper per image, provided you own a machine that runs it well.

On the browser side, $12.90 buys 500 one-time credits. A SeedVR2 image costs 25 credits, so 500 credits cover 20 images at that model; the Topaz model at 100 credits covers five. A $12.90 monthly Silver plan includes 1,000 credits, roughly 40 SeedVR2 images. The browser route is therefore cheaper for a handful of jobs and more expensive per image at high volume — the opposite of what a subscription usually implies.

Neither product recovers detail the source file never contained. Upscaling can sharpen edges, reduce compression noise and reconstruct plausible texture, but it cannot know the true shape of a face, a logo or a letterform that was already illegible. Compare the original and the result at the same display size, and at 100% for artifacts; a larger canvas can look better simply because the viewer smooths it differently.

There is also a privacy difference. Gigapixel can render locally, so the file never leaves the machine; a browser upscaler uploads it to a cloud worker. If the images are confidential, that difference may matter more than price. If they are ordinary product shots or screenshots, the browser route is the faster test.
