Increasing image resolution means enhancing its size and clarity, typically by adding more pixels to improve sharpness and visual detail. Whether you’re upscaling an old photo, prepping graphics for print, or delivering crisp images for high-DPI displays, several tools, from AI-based upscalers to built-in OS features, can help.
Let’s explore the most effective ways to increase resolution without compromising quality.
Image resolution refers to pixel dimensions (e.g., 1920×1080) or pixel density (PPI–pixels per inch). Increasing resolution can involve:
- Upscaling to larger dimensions
- Resampling the image using smart algorithms
- Enhancing clarity to avoid blur and pixelation
Enlarging an image without the right processing can lead to pixelation and loss of quality. Always use tools that intelligently resample the image.
With modern AI tools, images can be upscaled by factors of 2x, 4x, or more, while maintaining fine detail and sharpness. These solutions analyze patterns, textures, and structures to “predict” realistic pixel additions.
- Let’s Enhance
- Cloudinary
- Adobe Photoshop Super Resolution
- Upscale.media
- Pixelcut
- Upload your image to the platform
- Select upscale level (e.g., 2×, 4×, 8×)
- Download the enhanced version
These tools are great for quick enhancements, especially when you don’t need heavy manual control.
Photoshop is a professional tool that gives you precise control over image scaling.
- Open your image
- Go to Image > Image Size
- Check “Resample”
- Choose “Preserve Details 2.0” for interpolation
- Enter new dimensions or resolution (e.g., 300 PPI)
- Click OK
Photoshop uses smart algorithms to add pixels, ideal for graphic designers or photographers needing precision.
Windows Photos includes a built-in Super Resolution feature that enhances image size and clarity directly from the native app.
- Open the image in Windows Photos
- Click Edit → Super Resolution
- Select the enhancement level (e.g., 2×, 4×)
- Save the enhanced version
This is a convenient option for casual users and quick edits.

Learn more about Cloudinary image upscaling
The process of changing an image’s pixel count, either upsampling (adding pixels) or downsampling (removing them).
Used during resampling to estimate new pixel values. The method chosen affects the image’s clarity. Examples include:
- Bicubic Interpolation
- Preserve Details 2.0 (Photoshop)
Machine learning models predict and generate new pixels for more realistic and sharper images, especially useful when original detail is lacking.
- Some platforms (like Windows Media Player or certain photo apps) may require you to rescan your library to see enhanced images.
- Always use tools that support a wide range of image formats (JPG, PNG, TIFF) and offer flexible customization.
- Lossless formats (like PNG, TIFF) are recommended when saving enhanced images to avoid compression artifacts.
- Remember: AI can’t recover details that never existed, but it can generate realistic approximations.
