The number of pixels in a file is directly related to image quality. A higher resolution image packs in more pixels, those tiny squares that form the building blocks of your digital pics. The more pixels you have, the more information the image holds, and the sharper those fine lines and intricate textures become.

On top of that, if you're planning on blowing up a photo for a giant canvas or poster, a higher resolution is crucial to avoid a pixelated disaster. It's also important for professional applications like graphic design, where precision is key. That's why the demand of increasing image resolution has sprouted vigorously.

To improve an image quality from low to high, there are a diverse variety of ways to go including AI image enhancer toolkit, Photoshop, image editor, camera setting adjustment. Check the below tops ways to free increase resolution on a picture.

Step 4. Tap Run to begin upscaling image resolution after you select output image format (PNG or JPG).

Topaz Photo AI

Unlike Aiarty Image Enhancer supporting increasing image resolution up to 8X, this top image enhancement toolkit only enables you to convert low-resolution image to high resolution up to 6X original size. Yet, as a tradeoff, it comes loaded with more AI image modes, including upscale, denoise, sharpen, recover faces, remove objects, etc. to help you improve image resolution & quality, remove noise from low light, sharpen pixelated faces, feathers and fur, recover the details in faces.

Certainly, one thing to be noted is that Topaz is vulnerable to software crash when it comes to batch increase resolution on pictures in Photoshop or Lightroom as an add-on. You'd better control your batch process image quantity or just use the independent Photo AI program.

Pros
  • Simplicity. The interface is refreshingly uncluttered. Even editing novices can get great results with the intuitive sliders and the handy "Autopilot" mode.
  • The AI algorithms deliver impressive image upscale, noise reduction and sharpening, often surpassing what's possible with traditional editing tools.
  • Image upscaling speed is much faster than the one in the previous version.
Cons
  • Too expensive. The lifetime price goes to $199, no monthly or yearly plans.
  • Focus on the basics. While Topaz boasts new color and lighting adjustments, they feel underdeveloped compared to the core features.
  • Batch image resolution increase would encounter crash as a Photoshop or Lightroom plug-in.
  • Auto export image as Tiff format, not the DNG format users want.

Fotor Image Upscaler is a decent free option for anyone who wants to make an image high resolution up to 4X (16K resolution) without breaking the bank. It's easy to use, fast, and lets you reclaim some dignity for those less-than-stellar photos. However, if you need precise control or are working with seriously low-res images, you might be better off with a paid upscaler with more features.

Generally, Fotor Image Upscaler is a good tool to have in your back pocket, especially for casual users. Just remember, it's not a miracle worker, and free often comes with limitations. To be specific, you're only allowed to access to its limited package of AI & editing tools, download pictures in JPG/PNG/PDF format only in normal resolution instead of high resolution, and have to endure the annoying watermark, ads.

  • Easy to use.
  • Fotor processes your photos surprisingly quickly, especially compared to some other online free image upscalers.

Part 2. Increase Image Resolution and Quality via Image Editors

On top of the above-mentioned AI image enhancer programs, the traditional image editors like Photoshop, Lightroom are also strong performers to enhance the quality of a low-resolution image easy peasy. Cuz they also sport with the advanced artificial intelligence technology to help you improve image quality and resolution. Let's get closer to see how they increase the resolution of an image.

Adobe Photoshop

Adobe Photoshop is the highly-acclaimed image editor software that is almost used by everyone, newbies and experts. In the past, you might take advantage of Photoshop to trim photo, remove background from image, blur image, adjust picture saturation/brightness, or add text or special effects to picture, etc.

Now, with Super Resolution in Photoshop, you can make an image higher resolution (up to 4X pixels) while keeping image quality in good shape. They use advanced artificial intelligence (AI) and machine learning (ML) to intelligently select the best possible pixels for each specific image, ensuring superior quality. Then, you can use the higher resolution images for printing, E-commerce presentation, anime posters, art creation or social sharing.

Since both Photoshop and Lightroom have adopted the same AI tech - Super Resolution to improve image quality and upscale photo size, we just select one of them to show you the detailed guide. Here we use Photoshop for instance.

How to Increase Pixels of Image with Photoshop

Step 1. Click File at the top menu > Open > choose your image to load into Photoshop.

Step 2. Select Image > Image Size.

Step 3. Deselect Resample. This will automatically lock the current ratio of Width and Height.

untick Resample in Photoshop

Step 4. To improve picture Resolution, enter new values as you want. Photoshop will automatically change the Document Size to match.

Step 5. To adjust Document Size, add new values under Height and Width. Photoshop will again auto change the resolution to match.

Optionally, use Neural Filters to equally create a high-resolution image in your Photoshop app. Go to Filters at the top bar > pick up Neural Filters > tick Super Zoom > apply the slider to adjust the image to your liking > tap OK and that's it. Your Photoshop then will auto increase resolution on a picture.

Step 6. Now export your final image and save it as JPG or PNG.

GIMP

GIMP is a remarkable achievement in free and open-source software capable of improving image resolution up to 4X or 6X as you want. It offers a staggering array of features that rival paid editing programs like Adobe Photoshop. The customization options and vibrant community are a big plus. However, the steep learning curve and potential performance issues can be hurdles for beginners.

This image resolution enhancer is a powerhouse to free your creativity and free your wallet at the same time. But it's not for casual users or those who prioritize a user-friendly experience. For those who crave extensive features and customization without breaking the bank, GIMP is a free image upscaling toolkit waiting to be explored.

How to Free Make Image Higher Resolution with GIMP

Step 1. Open your image in GIMP. Go to Image > Scale Image.

Step 2. In the Scale Image dialog box, you'll see the current image size in pixels under Width and Height.

Step 3. Decide how much you want to increase the resolution. You can either enter a specific width and height in pixels or a percentage increase.

Step 4. Under Interpolation, choose an appropriate resampling method. Here's a breakdown of common options:

Nearest Neighbor: This is the fastest but least accurate method. It simply replicates the nearest existing pixel to fill in the new space, resulting in a blocky appearance.

Linear: This is a better option for most cases. It blends the colors of surrounding pixels to create new ones, resulting in a smoother image.

Cubic: This is the most accurate method but also the slowest. It considers a wider range of surrounding pixels to create new ones, resulting in the sharpest possible upscale.

Step 5. Click Scale to apply the changes.

Final Words:

While there's no magic bullet to conjure detail out of thin air, several tools and techniques can effectively increase the resolution of your images. Free options like GIMP with plugins offer decent upscaling capabilities, but require some learning curve and manual intervention. Online services like LetsEnhance.io provide a user-friendly, AI-powered approach, but limit free users or require subscriptions for higher-quality results. Paid software like Aiarty Image Enhancer, Topaz Gigapixel AI offer the most advanced upscaling with impressive detail preservation, but comes at a cost.

Ultimately, the best choice depends on your budget, technical expertise, and desired level of control. Remember, upscaling has its limits, and heavily processed images will always show some loss of sharpness. Start with the highest-quality image possible, and experiment with different tools to find the method that best suits your needs.
