Upscaler (free): make images bigger on your own computer
Free AI upscaling at 2x or 4x that runs on your own computer — no credits, no sign-in for credits. Quality tiers Standard, High and Extra High. Desktop app goes up to 8x.
ReadyPixl has two upscalers. This one, Upscaler (free), runs AI upscaling on your own computer (your graphics card or processor), so it costs nothing. The other one, [AI Upscale](ai-upscale), runs on our servers for 10 credits per image.
Try the free one first. If your computer handles it, you never need to spend anything.
How to use it
- Add Upscaler (free) to your pipeline.
- Pick a quality tier: Standard, High or Extra High. Start with Standard.
- Pick the Upscale Factor: 2x or 4x (4x is the model's native output; 2x runs 4x and then scales down to exactly 2x).
- Check the new size — the blue numbers under the preview are the size you'll download.
The first time you use a tier, ReadyPixl downloads the model it needs. Let it finish.
Be careful with slow computers
Speed depends on your machine. Higher tiers and bigger images can crash a slow PC or Mac. Test Standard first, then move up only if your computer keeps up.
If your computer struggles or crashes, turn the free Upscaler off and use [AI Upscale](ai-upscale) instead — it runs on another computer, so your machine's power doesn't matter.
Web vs desktop
| Web version | Desktop app | |
|---|---|---|
| Where it runs | In your browser (needs WebGPU) | Natively on your computer |
| Factors | 2x, 4x | 2x, 4x — and up to 8x on Extra High |
| Cost | Free | Free (included with the app) |
On the web, 8x is only available in the paid AI Upscale.
Tips
- Upscale before Reposition, so the bigger image is what gets placed on your canvas.
- A 1024 × 1024 AI image at 4x becomes 4096 × 4096 — then Reposition can place it on whatever canvas size you need.
- Don't run the free Upscaler and AI Upscale in the same pipeline unless you really want to upscale twice.
