Ever stumbled upon one of your all-time favorite images and wanted to post it so hard but realized it was a low-resolution image? You try to enlarge it, but it becomes blurry, pixelated, and just plain unusable. It frustrates, right, and we've all been there.
Resizing a low-resolution image increases its dimensions but doesn't add new pixels; this results in a loss of quality.
The good news is you don’t have to give up on those images anymore. In this guide, we’ll cover traditional tools like Photoshop, as well as popular AI-powered upscalers such as Pixelbin, Picsart, and Clipdrop. Let’s dive in and make your images sharp, clean, and ready for anything.
What is image resolution?
Image resolution refers to the amount of detail an image holds, which is measured in pixels, dots per inch (DPI), or pixels per inch (PPI). The higher the resolution, the sharper and clearer the image appears. Know the features of image resolution in detail.
- Pixels: The smallest units of an image. More pixels = more details.
- DPI/PPI: Dots per inch is used in printing; Pixels per inch refers to screen resolution.
- High-resolution: It is suitable for advertisement, printing, and professional images for websites or social media posts.
- Low-resolution: This is best for quick sharing of images through transferring apps or messaging apps, but it is poor for enlargement.
Why do you need to upscale image resolution?
Resolution isn't just about how big an image looks—it determines how clear it looks, especially when enlarged. Here's what you need to know:
- Image size vs. resolution:
- Image size is the physical dimensions, like how big the image is in terms of width and height (like: 1600 × 1780 pixels) / (width × height).
- Resolution is the pixel density in easy language; it's about how tightly packed the pixels are.
- Why image resolution matters:
- For printing an image- A high number of dots per inch makes your prints come out clearer and sharper.
- For viewing on screens- Higher resolution images look better on retina displays.
- For editing an image- high pixel count makes you crop, zoom, or tweak the image without losing quality.
How to upscale image resolution using traditional methods
Traditional tools can offer manual control, especially for people who know photo editing. Let’s look at three popular options.
1. Adobe Photoshop
What I liked: Photoshop gives you manual control in a professional way that’s hard to beat. You can manually sharpen images, reduce noise, and even upscale them. I tried it on a low-quality photo first, cleaned up the noise, and then used the Preserve Details 2.0 feature (thanks to the AI plugin I have) to upscale it. The image looked much clearer, and all those blurry areas were gone.
Steps to upscale image resolution in Photoshop:
Step 1: Open your image in Adobe Photoshop, then select File> Open.

Step 2: After adding the image, go to Image and then Image Size.

Step 3: Add the width and height proportions, and then tick the Resample checkbox.

Step 4: Preview the upscaling of the image.

Step 5: Export the image in PNG format.

2. Microsoft Paint
What I liked: It’s free and extremely easy for quick edits. It was not so ideal for enhancing image quality, but it can be used to resize without much effort.
Steps to upscale image resolution in Paint:
Step 1: Open the image in Paint.

Step 2: Click on Resize.

Step 3: Choose Pixels and uncheck “Maintain aspect ratio” if needed.

Step 4: Enter desired dimensions.
Step 5: Save as PNG for better output.

3. GIMP (GNU Image Manipulation Program)
What I liked: GIMP is totally free yet packed with powerful features. Its interface is a bit like Photoshop and a bit complex for beginners. Once you get used to the interface, it's super handy for editing, retouching, and even upscaling images.
Steps to upscale image resolution in GIMP:
Step 1: Launch GIMP and open the image you want to upscale by going t File and then Open.

Step 2: Go to Image and then select the Scale Image dialog.

Step 3: In the scale image, you can modify the width and height to any desired size by choosing the ratios.

Step 4: Choose the cubic interpolation method.

Step 5: Click on the scale button to apply the changes.

Step 6: After the final results, go to file and export as, choose a file name, and click on export, and your upscaled image will get saved.

Yes, especially using AI tools like Pixelbin or Upscale.media, which intelligently add missing details and smooth out edges to maintain sharpness by upscaling images without losing quality.
Upscaling can improve visible sharpness and size, but doesn’t “add” real detail. AI tools simulate added quality through pattern recognition and enhancement.
Many AI upscaling tools offer limited free versions like Pixelbin, Upscale.media and few more. For higher resolution output or batch processing, a premium plan may be required.
PNG and TIFF are ideal for saving high-quality images. They preserve details without lossy compression, unlike JPEG, which can degrade over time.
