Cerebrum Scale

Cerebrum Scale is a Windows desktop app that upscales your images on your own machine. No cloud uploads. No API keys. No per-image quota nagging at you every month. You point it at a folder, pick one of three AI models, and let your own GPU do the sharpening while the source files stay put on your drive.

Most image upscalers today lean on a web service. That works until you hit a monthly cap, until a client hands you a batch you're not allowed to upload anywhere, or until the browser tab crashes on the seventeenth photo of a wedding gallery. Cerebrum Scale takes a different route: a native Windows WPF app that runs ONNX models locally through DirectML, so the graphics card you already paid for actually earns its keep.

What Cerebrum Scale actually does The pitch is narrow on purpose. This is not a Photoshop replacement, and it doesn't try to be. It does one job — 2x and 4x AI upscaling — and it does it as a batch tool on your own hardware.

• Upscales images 2x or 4x with local ONNX Runtime models
• Runs 100% offline; no APIs, no subscriptions, no usage limits
• Ships with three built-in AI models tuned for different image types
• DirectML GPU acceleration on Windows
• Batch queues for entire folders, with start, pause, and resume
• Tile-based rendering for very large files
• Reads PNG, JPG, JPEG, BMP, WebP; exports PNG, JPG, or WebP

The features that matter A few of the smaller choices do more work than the headline number. Switching between the three bundled models matters when you're moving between crisp product shots and softer illustration work — the same algorithm rarely flatters both. Tile size control is the setting most people miss on the first pass; it lets you push a strong GPU harder or ease off on an older laptop, which is often the difference between a batch finishing overnight and dying in the middle.

The before-and-after compare window is the other quiet win. You can zoom in on the upscaled version next to the original and only export the images that actually improved, instead of exporting everything and cleaning up afterward. Format conversion happens in the same pass, so a folder of BMP scans can come out as WebP without a separate export step. Processing history and per-run statistics are handy the morning after an overnight batch, when you want to know what finished and what didn't.

Who it's built for Cerebrum Scale is for people whose work is measured in gigabytes of images and whose patience for browser-based upscalers has run out. If you're already paying a subscription to a web tool every month, or you handle client work you cannot upload to a random server, the offline model changes the math. A dark native Windows interface won't win any design awards, but it stays out of the way and doesn't fight your OS.

Practically, that maps to photographers cleaning up old scans and client galleries in bulk, graphic designers preparing hero images and print-scale assets, print designers who need honest 4x pixels rather than a hopeful browser preview, content creators repurposing thumbnails and social graphics, and freelancers whose turnaround times cannot depend on somebody else's queue.

The trade-off is honest: you're bringing your own hardware. A modern GPU with DirectML support turns a 100-image folder into a coffee break; an older laptop turns it into an afternoon. Either way, the images never leave your machine, which is the part that matters for anything you can't send to a third-party API.
