My experience with Aiarty Image Enhancer and final image showcase:

I could use Aiarty Image Enhancer to batch convert multiple images by 800% up to 32K resolution, and it worked very fast and outputed great final images. It only took me a few minutes to upscale my image to the highest resolution (32K) even though my computer was not very powerful. Besides increasing image resolution, it could denoise, deblur, and sharpen my images, so my images became extremely clear and full of details. Even when I enlarged the final images, there is no blur or pixelation.

Way 2. Convert Images to High Resolution with Adobe Photoshop

• Max upscaling: 4X
• Supported platforms: Windows, Mac
• G2 rating: 4.6/5

Adobe Photoshop’s AI-powered Super Resolution feature doubles the linear resolution, quadrupling the pixel count of low-res images. Using AI and machine learning, it selects the best pixels to deliver sharp, detailed results ideal for high-quality prints. With one click, you can effortlessly enhance images and increase resolution to 4K or 8K in Photoshop.

How to increase image resolution with Photoshop’s Super Resolution?

Step 1. Open a raw file first. The raw files would open up automatically in the Adobe Camera Raw tool.

Step 2. Right-click the shot & choose Enhance. An Enhanced Preview dialogue box will appear, with a few options for managing the procedure.

Step 3. Check the Super Resolution checkbox, and pan around the preview image to see the expected results. Then, click the magnifying glass icon to zoom out, and then click back on the patch you want to investigate.

Step 4. Click the Enhance option.

Step 5. After that, zoom in close enough to fine-tune aspects like sharpness, texture, and noise removal by using scales on the right. Check detailed steps to convert images to high resolutions in Photoshop >>

Notice: If you want to use Super Resolution with JPEG, HEIC, or TIFF files, first you need to set Photoshop to open those file formats in Adobe Camera Raw by default. You can do as follows:

1. Browse the File Handling section and select Camera Raw Preferences from the menu.
2. When a dialog box appears, select the File Handling area.
3. Change the JPEG/HEIC option to "Automatically open all supported" images, then repeat the process for TIFF files if required.

My experience with Photoshop's Super Resolution and final image showcase:

Adobe Photoshop, while a professional tool, may not be ideal for beginners needing simple resolution upscaling. Its Super Resolution feature only upscales images by 4x, up to 8K or so, which may not be enough for very high-resolution needs. Zooming in on upscaled images may show less detail. After testing, Adobe Photoshop demonstrates improved performance with higher-resolution images; images with dimensions lower than 800x600 pixels may not produce satisfactory outcomes.

Way 3. Increase Image Resolution with Topaz Photo AI

• Max upscaling: 6X
• Supported platforms: Windows, Mac
• G2 rating: 4.0/5

Topaz Photo AI is a cutting-edge image enhancer that uses advanced AI algorithms (Autopilot) to upscale, restore, and optimize images, delivering stunning results.

How to convert images to high resolution with Topaz Photo AI?

Step 5. Optionally, manually adjust the parameters to perfect your image(s).

Step 6. When everything is OK, hit the "Export image" to upscale and export the image(s).

My experience with Topaz Photo AI and final image showcase:

Topaz Photo AI demonstrated exceptional proficiency in processing images of animals, such as tigers, cats, and birds. The resulting images exhibited remarkable clarity and sharpness in the fur and other features. Also, it allowed me to export PNG, JPG, DNG, or TIFF format as well. However, it appeared that Topaz Photo AI struggles with face processing. A comparative analysis between Aiarty Image Enhancer and Topaz Photo AI also indicated that the facial images produced by Topaz were significantly blurrier than those generated by Aiarty.

Way 4. Free 16K Photo Converter Online – Upscale.media

• Max upscaling: 8X
• Supported platforms: Online
• G2 rating: 4.8/5

Upscale.media is a free and user-friendly photo 8K converter online that uses advanced AI to upscale images by up to 8x, reaching a maximum output resolution of approximately 10K (e.g., 1,200px source image upscaled to 10,000px). While it doesn't offer true 16K/32K output, it's still a handy option if you're looking to convert image to high resolution alternatives or need ultra-high-resolution images for digital displays, large-format prints, or presentations. This online AI tool supports JPEG, PNG, WebP, and HEIC formats, making it ideal for users who want quick, installation-free image enhancement directly in their browser.

How to use Upscale.media as a 16K photo converter?

Step 1. Visit the official site: https://www.upscale.media/ and click "Upload Image" to upload your photo in JPEG, PNG, JPG, or WebP format.

Step 2. Choose between "Normal Upscaling" (2x) and "AI Upscaling" (up to 8x). To reach near-16K resolution, upload a high-quality source image and apply 8x scaling.

Step 3. Toggle "Enhance Quality" to boost sharpness and clarity.

Step 4. Click "Download Image" to save your enhanced, high-resolution photo. For large images, consider compressing afterward to meet file size limits (max output: 25MB).

My experience with Upscale.media as a 16K converter:

While not a full 16K output tool, Upscale.media offers a free, online method to convert image to high resolution. I tested it with a 1024x1024px image, and the 8x upscaling brought it close to 8K–12K levels. However, the upload was slow, and the tool struggled with images exceeding 1500px input resolution. Final images were somewhat brighter but still lacked detail at extreme zoom. Overall, it’s a decent 16k photo converter online free solution for moderate use.

My experience using VanceAI as a photo 16K converter online free:

In free mode, VanceAI limited my output to around 2.8MP, which is enough for quick previews but not sufficient for ultra-high-resolution use. After upgrading, I was able to generate images up to 34MP, approaching 10K quality. Although it can’t fully convert images to 16K resolution, it remains one of the most accessible AI-powered tools for high-quality upscaling, especially for those looking for an online solution without installing software.
