Topaz Gigapixel AI on your Mac — 1.4.0

Topaz Gigapixel AI is a desktop application that uses neural networks to enlarge images while preserving detail and clarity.

Upscale first, then edit in your photo editor

• Works alongside your existing photo editor — upscale first, then edit.
• Handles batch processing for multiple files at once.
• Cleans up low-quality line art and PNG files without introducing artifacts.
• Restores detail in old scanned photos before you colorize or retouch them.
• Runs natively on Apple Silicon and Intel Macs (macOS 12 or later).

Fill in missing details from millions of learned patterns

Unlike simple bicubic enlargement, Gigapixel AI analyzes each image and fills in missing information based on patterns it learned from millions of photographs. The result is an upscaled image that looks natural rather than pixelated. The legacy Gigapixel AI line ended with version 8.4.4, but the current 1.3.5 continues as a separate product with native Apple Silicon support.

Expecting miracles from tiny, heavily compressed JPEGs

The most frequent error I see in the game club is people expecting the AI to work miracles on a tiny, heavily compressed JPEG. The tool adds detail based on what it has learned, but it cannot invent a face from a five-pixel-wide thumbnail. Feeding it a very small source with extreme compression artifacts often produces unnatural results, especially in skin textures and fine hair.

Another mistake is upscaling everything by the same factor. A portrait from a low-resolution webcam might benefit from 4x enlargement, but a sharp photo taken on a decent phone might only need 2x. Blindly applying the highest setting adds processing time and can introduce unnecessary smoothing. Start with 2x and check the preview before going higher.

Beginners also forget to check the preview at 100 percent zoom. The default view in the application shows the full image, which hides artifacts and soft areas. Zoom in to a section with fine detail, like text or foliage, and compare the before and after side by side.

Batch processing without reviewing individual results is another pitfall. The AI handles most images well, but every so often a high-contrast edge or a busy pattern confuses the model. A quick glance at each output saves you from finding a blurry result later.

Preprocess before Affinity Photo, Pixelmator Pro, or Photoshop

Gigapixel AI works well as a preprocessing step before you open an image in Affinity Photo, Pixelmator Pro, or Adobe Photoshop. Upscale first, then do your color correction, sharpening, and retouching. The enlarged file gives you more room to work with when making selections or applying filters.

If you use Apple Photos for everyday organization, you can export a photo from the library, upscale it in Gigapixel AI, and import the result back. The original low-resolution file stays untouched, and the new version sits alongside it. For larger projects, I keep a folder of source images, process them in a batch, and move the upscaled copies into my editing app of choice.

macOS Quick Actions can also be useful. After saving a processed image, you can right-click it in the Finder and run a shortcut that opens it directly in your editor. The file format stays the same, so there is no conversion hassle. On Apple Silicon Macs, the app launches quickly and uses the neural engine efficiently, which keeps the rest of the system responsive during long batch jobs.

Fractal-based alternative vs. AI pattern analysis

Gigapixel AI is one of several upscaling tools for macOS. Here is how it stacks up against a few alternatives.

ON1 Resize. Formerly known as Genuine Fractals, ON1 Resize uses its own fractal-based algorithm for enlargement. It produces clean results on photographs with smooth gradients, but it can struggle with highly detailed textures and line art. Gigapixel AI tends to handle those cases better because its neural network has been trained on a wider variety of image types, including illustrations and old photos.

Upscale by Sticker Mule. This is a simpler, web-based tool that uses AI for enlargement. It requires an internet connection and has no batch processing on the desktop. For a single image now and then, it works, but anyone handling multiple files or working offline will prefer Gigapixel AI's local processing and folder-based batch mode.

PhotoS upscaler. Another desktop option, PhotoS focuses on portrait and face enhancement alongside enlargement. It does a good job with skin and eyes, but its general upscaling is less refined than what you get from Gigapixel AI's trained models. If you primarily work with portraits, PhotoS might be worth a look, but for mixed content, Gigapixel AI is more versatile.

Can it work with RAW files?

Several questions come up regularly when I recommend this tool to other teachers and photographers. Here are the ones I hear most often.

Can I use it with RAW files? Gigapixel AI works with the common image formats like JPEG, PNG, and TIFF. It does not open RAW files directly. Convert your RAW images to TIFF or JPEG first, then upscale. This gives you a larger file to work with in your RAW converter afterward.

Does it work with older Macs? The current version requires macOS 12 or newer and supports both Intel and Apple Silicon Macs. If you have an older Mac running an earlier version of macOS, you would need to use the legacy Gigapixel AI line, which ended at version 8.4.4. The 1.3.5 build will not install on systems older than macOS 12.

Will it slow down my computer during processing? The app uses your Mac's GPU and neural engine to process images, so it does demand resources while a batch is running. On Apple Silicon machines, you can still use other apps during processing, though they might feel a little less responsive. On Intel Macs, it is best to let a batch run and step away for a few minutes.

How long does a batch take? That depends on the image size, the enlargement factor, and your Mac's hardware. A 2x upscale of a standard JPEG might take a few seconds per image on an Apple Silicon Mac, while a 4x upscale of a large TIFF could take a minute or more. The preview lets you test a single image before committing to a full batch.

Can I undo the changes? The application saves the output as a new file by default. Your original image stays untouched. If you do not like the result, you can delete the upscaled copy and try different settings. There is no nondestructive editing like in Lightroom, so keep your originals safe.
