AI Image Upscaler: Best Free and Paid Tools in 2026 to Enlarge Photos Without Blur

An AI image upscaler can make a small photo big enough to print, crop or use as a website banner, without the blocky blur you get from normal resizing. As a result, old family photos, low resolution product shots and screenshots can look far sharper than before.

However, not all upscalers work the same way. For example, some add pixels carefully, while others invent new detail. In this guide, we compare the best free and paid AI image upscaler tools as of October 2026, explain how they differ, and show when to trust the result.

What an AI image upscaler does

Normal resizing simply stretches pixels, so edges look soft. In contrast, an AI image upscaler predicts what the missing pixels should look like, based on millions of example images. For instance, Adobe’s Super Resolution doubles both width and height, which means four times the total pixel count, as its help page explains.

It also helps to know what upscaling is not. For example, sharpening keeps the same number of pixels and only boosts contrast at edges. Upscaling, on the other hand, adds new pixels.

Two kinds of AI upscaling

Faithful upscaling. In short, these models try to keep the image true to the original. They suit product photos, documents and family pictures.

Generative upscaling. Tools such as Magnific, Krea and some Topaz models invent fine detail, like skin texture or leaves. At first, the results can look stunning. However, they can also change faces, text and logos, so check them closely.

Best AI image upscaler tools compared

Prices come from each company’s official pricing page and may change by country.

Topaz Gigapixel

To begin with, Topaz Gigapixel is a favourite of photographers. The product page says it can upscale almost any image six times, with models for faces, text, art and low resolution shots. It runs on Mac and Windows, on its own or as a plugin for Photoshop and Lightroom Classic. In addition, the Personal plan costs $149 a year, which works out to about $12 a month.

Adobe Photoshop

Photoshop offers two options. First, Super Resolution in Camera Raw doubles the width and height of a photo. Second, Generative Upscale can enlarge images 2x or 4x using generative credits. According to Adobe’s help page, the Firefly upscaler outputs up to 6144 by 6144 pixels. The same tool also offers premium Topaz models. Photoshop costs $22.99 a month on an annual plan with 25 generative credits a month, and each Firefly upscale uses 5 to 10 credits, so the monthly credits cover only a few upscales.

Upscayl

Upscayl is a strong free choice. It is free and open source, runs on Windows, macOS and Linux, and can upscale up to 16x. Because the desktop app runs on your own computer, your photos stay on your device. However, it needs a Vulkan compatible graphics card, and most integrated graphics chips will not work, as its GitHub page notes.

Canva

Meanwhile, Canva’s upscaler is built into the editor. Its help page says it picks 4x or 16x automatically, outputs up to 50MP, and accepts JPG and PNG files up to 25MP. Free users can use it within their AI allowance, so it is handy for quick social images.

Let’s Enhance

Let’s Enhance works in the browser and suits large prints. New users get 10 free credits, but free results carry a watermark and are capped at 8MP. Paid plans start at $9 a month billed yearly and allow much bigger outputs.

Krea

Krea is a creative tool with a generative upscaler for images and video. The free plan gives a small daily allowance, roughly four enhanced images a day. Paid plans start at $5 a month billed yearly, or $9 billed monthly. It suits artists who want extra detail rather than strict accuracy.

Pixlr

Pixlr’s Super Scale tool upscales 2x, 3x or 4x, up to 5000 by 5000 pixels, in the browser. Plans start at $1.99 a month billed yearly, so it is a budget friendly option.

Tips for better results from an AI image upscaler

1. Start with the best source. First, use the original file, not a compressed copy from a chat app.
2. Upscale in steps. For example, try 2x first, check it, then go further if needed.
3. Pick the right model. For example, use face models for portraits and text models for screenshots.
4. Zoom to 100%. Then, check eyes, hair, letters and edges for odd patterns.
5. Avoid generative models for evidence. For news, insurance or documents, use faithful upscaling only.

When an AI image upscaler can mislead

Generative upscalers can add detail that never existed. For instance, a blurry face may come back sharp but slightly different. Therefore, do not present a heavily upscaled image as an exact record. Our guide on how to tell if a photo is AI generated explains how people spot these changes.
