Most Designers Don't Know Photoshop Can Upscale Images 4x and Regenerate Missing Detail
Photoshop 2026 has a built-in Generative Upscale that doesn't just enlarge photos—it rebuilds them with AI, turning low-res web images into print-ready files in one click.
01. What It Is
For years, the golden rule was simple: enlarge a low-resolution image and it turns to mush. Photoshop 2026 breaks that rule with Generative Upscale, found under Image > Generative Upscale. Instead of stretching existing pixels, it uses Adobe's Firefly AI model to regenerate the entire image, inventing believable detail—sharper edges, cleaner textures, and defined features that simply weren't in the original file.
You can scale at 2x or 4x, and the result is written to a brand-new document so your original is never touched. The default Firefly Upscaler can output images up to 6144×6144 pixels, and processing typically takes just 1 to 3 minutes depending on your computer's power. For photographers who prefer a RAW-first workflow, Adobe Camera Raw offers a related feature called Super Resolution (right-click > Enhance) that doubles each side—quadrupling total pixels—using machine learning rather than a plain pixel stretch.
There's also a premium tier: through Generative Upscale you can switch the engine to Topaz Gigapixel (up to 56 megapixels) or Topaz Bloom (up to 9 megapixels), both of which require a premium subscription. Everything is built directly into Photoshop and Camera Raw—no third-party plugins to install.
Why It Matters
This turns unusable images into deliverable assets. A grainy vintage scan, a small web-sourced photo, or a low-res client logo can become a large, clean print file without an expensive external tool or a costly reshoot. What used to require Topaz as a separate purchase or a full reshoot now happens inside Photoshop in a couple of minutes.
Who Can Benefit
- Graphic designers rescuing low-res client assets for print
- Photographers restoring old or small scans
- Social media and marketing teams repurposing web images at larger sizes
- Print shops needing higher-resolution source files
- Hobbyists reviving family photos
02. Step-by-Step Guide
- 1
Open your low-resolution image
Launch Photoshop 2026 and open the small or low-quality photo you want to enlarge. Any standard raster image works.
- 2
Go to Image > Generative Upscale
From the top menu bar, choose Image, then Generative Upscale. This opens the upscale options rather than the classic Image Size dialog.
- 3
Choose 2x or 4x
Select your scaling factor. Generative Upscale supports fixed 2x or 4x—there is no free variable slider. Keep in mind Firefly outputs up to 6144×6144 pixels.
- 4
Pick your AI engine (optional)
By default it uses the Firefly Upscaler to regenerate detail. If you have a premium subscription, you can switch to Topaz Gigapixel (up to 56MP) or Topaz Bloom (up to 9MP) for different rendering styles.
- 5
Run it and wait 1–3 minutes
Start the process. Depending on your hardware, the AI rebuilds the image in about one to three minutes and delivers the result in a new document, leaving your original untouched.

Try Super Resolution for RAW workflows
For RAW, DNG, TIFF, HEIC, JPEG, PNG, or GIF files, right-click the image in Adobe Camera Raw and choose Enhance > Super Resolution to double each side (4x total area) with AI-added detail.
Pro Tips
- Use Camera Raw's Super Resolution for very large targets—it supports up to 65,000 pixels on the long side or 500 megapixels total, far beyond Generative Upscale's limits.
- Because output lands in a new document, you can run multiple engines on the same source and compare results side by side.
- For faces and fine textures, 2x often looks more natural than 4x—AI regeneration can over-invent detail at extreme scales.
- Topaz Gigapixel's 56MP ceiling makes it ideal for large-format prints when the Firefly limit isn't enough.
Warnings & Limitations
- Generative Upscale has a maximum output of 4096 pixels on the longest edge per Adobe's official documentation—plan around that limit.
- Firefly regenerates detail, meaning it invents pixels; results may differ from reality and aren't suitable for forensic or evidentiary use.
- Topaz Gigapixel and Topaz Bloom require a premium subscription and are not part of the standard feature set.
- These features are built in as of Photoshop 2026 and current Adobe Camera Raw—older versions won't have them.
