Tired of Blurry Upscales? Try These Image Enlarger Apps and Online Tools

AI image enlargers upscale low-res photos by adding realistic detail and sharpness while increasing dimensions (e.g., 2x, 4x, 8x) without the usual pixelation or blurriness. This makes small images suitable for large prints or digital displays by predicting and creating missing pixels, not just stretching them.

This guide covers the best free AI image enlarger tools that you can start using immediately. These tools require no registration and work on both Mac and Windows PC, and some on mobile browsers, too.

Part 1. 11 Best Image Enlarger Apps and Online Tools

Here are the top 11 image enlarger online tools and software you can use on your device to upscale with ease.

1. HitPaw AI Image Upscaler

HitPaw offers the most convenient and simple tool to enlarge your images up to 8K or 400% through its AI image upscaler embedded in the photo enhancer. The results you get are amazing, and the visuals turn out to be very high-quality. That's a steal, as the tool is 100% free to use online.

Not only that, you can edit your images using HitPaw AI models, like improving the facial features, removing noisy elements, converting black & white photos to color, and restoring those old shots with a single click.

The processing speed is lightning fast, and you get the downloadable results in seconds.

2. I Love IMG

I Love IMG has been around for a long time, and many users use it to enlarge their images. The process is fairly easy.

On the homepage, go to the "Upscale Image" option and select the AI photo or photos you want to upscale. You can choose between 2X or 4X resize.

This tool is pretty bare bones-you don't get different models to choose from. But looking at the before and after, it adds noticeable clarity to the uploaded image.

Some artifacting is removed, and the overall visual result looks better. Once you're satisfied, click "Upscale" and then download your photos on the final screen by clicking "Download Upscaled Images." Batch enlarging is supported as well.

3. Upscale Media

Upscale Media is another fantastic free online image enlarger tool. Upload your image and select the upscale amount, up to 8X. To keep things consistent, set it to 4X. When hovering over the image, you'll see a small preview. The final result still contains some artifacting but ends up sharper than the original.

Considering the additional upscaling feature and a few extra settings, Upscale Media might be preferable over many other tools. Once you're done, just click "Download Image," and you're good to go.

4. Upscayl

Upscayl requires a download. On the homepage, if you click the Mac OS option, it takes you to the App Store for a paid version. But by going to "Alternative Downloads" and selecting Mac OS, you'll find the DMG free download. Download and install that version. If you're on Windows, it should work similarly, though you may want to double-check.

Once installed, open the program. Inside, select your image. You'll get several different models to choose from, which already puts this ahead of the first two options. You can try different models, but for consistency, go with the "High Fidelity" model.

You can also adjust the upscale amount. However, past a certain point, you'll see an error message warning about possible rendering issues based on your device. Try to avoid going past that warning, depending on your system specs. Next, set the scale to 4X to match the other examples. Then, choose your output folder and click "Upscale".

One big advantage here is batch processing. You can upscale multiple images at once and select models for each. This makes it a very useful tool. After enlarging, check the output folder you set earlier to view the final result, since the before-and-after preview inside the app isn't the final saved version.

5. DGB.LOL

The next image enlarger on the list is dgb.LOL. For some reason, it looks like a joke, but if you don't have a powerful system, this is the one to try. You can go to the "Tools" section. There are a lot of free tools there: image upscaler, Midjourney splitter, background remover, and more.

Try the image upscaler tool. The website is run by ads, and that's how it's funded. If you don't want to see ads, you'll have to pay. But since you're looking for a free option, just drag and drop your photo.

You also get the option to choose which model you want for upscaling. Keep it set to "Balanced" and click on "Submit".

Now here's the catch with this platform. If you go to "My Files," you'll notice your file is in the queue. Just like a food center handing out free food, you've got to wait your turn. A lot of people are trying to get that free food, and the same thing happens here.

In this case, the wait time goes up to 15 minutes.

6. Pixelcut.AI

Pixelcut AI can quickly improve the quality of your images and enlarge the resolution to 4K to 16K. The best bit is it's fast, free, and online.

Inside the "Edit" section on the homepage, you'll find the image upscaler. No sign-up is required. If you want to batch upscale, that part's paid. That's the one edge Upscayl (the one with a Y) has over this. It lets you batch upscale for free using your system resources.

Upload the portrait and choose to upscale 4X. Let it process and click 4X. The upscale result is decent.

There are some unnecessary halos here and there, but you'll compare that with others soon. Also, if the background in the original image is out of focus, it can somehow make it look focused and sharp.

7. ON1 Resize AI

While enlarging an image, most tools blur, stretch, or guess on pixels, and that's why your photos can look blurry, soft, or even a little fake. This is because these tools don't actually add detail. They just make the pixels bigger. But with On1 Resize AI, you can make the photo larger and still keep it sharp and full of detail.

ON1 Resize AI uses advanced AI technology to actually rebuild detail as you upscale. It's trained on everything like faces, textures, and edges. That means natural sharpness without artificial smudging. No weird artifacts, just clean, realistic enlargement. Whether you're cropping into a wildlife shot or preparing a massive print, Resize AI keeps your image looking incredible.

And don't just take someone else's word for it. Real users have reported amazing results with Resize AI while restoring an old face or prepping a large gallery print. ON1 Resize AI consistently delivers detail where it matters most.

You can even batch-enlarge full folders of images quickly. Recover faces with accuracy, and prep prints using tiling and gallery wrap tools. Furthermore, you can use it as a standalone app or as a plugin in your favorite software.

8. Image Larger

Image Larger is a pretty straightforward website. It also has its own software, but you can just enlarge images online as well.

All you need to do is click the button, locate your low-resolution photo, select it, and click "Open." Then choose how you want to upgrade it. If it's a face, select "Face Photo"; if it's artwork, go with that. Just leave it at "High Grade - Recommended." You may have tried all settings before, and in that case, "High Grade" gives the best results.

Set it to 4× resolution increase and click "Start." While it's processing, keep in mind there's an upload limit of 1200×1200 pixels and files must be under 5MB. Premium versions are also available. If you check pricing, there's a paid plan for 99 images per month, and another one for more. The free plan gives you 19 images per month.

Once it finishes processing, download the image. Just note, this platform is a bit pricey. The free version allows only 19 images per month, and then the cost increases.

9. Let's Enhance

The next image enlarger is LetsEnhance.io. You need to create an account to use it.

If you're on a free plan, you'll get five images. Head over, upload your low-res portrait, select the image type, and the options here are "Photos and Art" or "Illustrations".

Skip the color enhancement and texture options if you're not using them. In the advanced settings, set upscale to 4X. 8X requires payment. JPG format is fine, and start the processing.

The tool finishes fairly quickly. Download the result.

The output removes subtle details. While the result is softer and looks pleasant, the downside is that it loses too many details compared to other image enlargers.

10. BigJPG

BigJPG has an app for every device and offers you to enlarge images online as well. It provides you with a higher resolution limit, up to 3000×3000, and a 10MB file size cap, which is more than many image enlargers.

In the free version, upload your low-res portrait, and choose "Photo" as the image type. Set it to 4X. Skip noise reduction if not needed.

Processing takes about six minutes, during which you'll see ads and some upsell offers for premium features. They don't show prices clearly unless you log in, which isn't ideal. Sites that hide pricing often charge people differently, which doesn't feel fair.

Once complete, download the result. BigJPG sometimes introduces odd lines on the nose, which look off.

11. Gigapixel AI (Topaz Labs)

The last image enlarger is Gigapixel AI by Topaz Labs, and it is expensive. If you've tried the free trial already, you'll need to buy it, which costs around $75.

Once installed, open the image you want to enlarge. Set the upscale amount to 4X. Keep "Auto" settings and enable face refinement. Choose JPG format for export. For the desktop app, you don't need internet access. That's a plus.

Start processing and download the enlarged photo.

Surprisingly, for a paid tool, Gigapixel AI introduces thin horizontal lines throughout the image. These lines aren't noticeable at first, but when printed, they become visible.

Whether it's a Windows bug or a software flaw, it ruins the image. For something that costs $75, that's unacceptable.
