4 Best Free AI Image Upscaler Websites and Apps
Enlarge small or blurry photos with AI. Free image upscalers compared: Upscayl, Let's Enhance, Upscale.media and Pixelcut, with their free limits.
Here is a list of best free AI image upscalers. A normal resize just stretches pixels, so an enlarged photo looks soft and blocky. An AI upscaler instead predicts the missing detail, which lets you turn a small web image, an old scan or an AI-generated picture into a larger, sharper file suitable for printing or a high-resolution screen.
Online upscalers are convenient but almost always limit free use with credits, and some add a watermark. A free desktop app avoids those limits because it uses your own computer’s graphics card. Both kinds are listed below.
Top Pick:
Upscayl is the best free choice if you can install an app. It is open source, has no usage limits or watermarks, and works offline on Windows, macOS and Linux.
For a quick online upscale with no install, Pixelcut or Upscale.media are the simplest.

Upscayl
Upscayl is a free and open-source AI image upscaler for Windows, macOS and Linux. Choose an image or a whole folder, pick a model (there are models for general photos, digital art and sharper detail) and select 2×, 3× or 4× enlargement. A “double upscayl” option runs two passes for even larger output.
Because everything runs on your own computer, there is no account, no upload and no limit on the number of images. It works best with a GPU that supports Vulkan; on older hardware it is slower but still usable.
| Pros | Cons |
|---|---|
| Completely free, no limits or watermark | Must be installed |
| Batch-upscale entire folders | Needs a reasonably modern GPU for good speed |
| Works offline, photos stay private |
Let’s Enhance
Let’s Enhance is a popular online upscaler aimed at photographers and online sellers. New accounts get 10 free credits, and free results can be upscaled up to 8 megapixels.

Use the free credits to judge quality before deciding whether you need a paid plan for print-size output.

| Also fixes lighting and JPEG artifacts | Only 10 free credits |
