How to Enlarge Image without Losing Quality? 8 Tools Tested
Updated on
Have you ever tried to enlarge an image only to end up with a blurry, pixelated mess? It’s a common problem. When you increase the size of a raster image, new pixels must be added, and without the right technique, those pixels often turn into visible artifacts and loss of clarity. The good news is that modern AI image upscalers can enlarge images without losing quality by intelligently generating new details and restoring texture.
In this guide you’ll get:
- A short, actionable how-to that works right now (three quick methods: free online, Photoshop, and AI upscaling).
- Real test results from 8 image enlargers so you know which tools actually preserve texture and clarity.
- Practical tips for printing, exporting, and avoiding the common pitfalls that make enlargements look fake.
How to Enlarge an Image Without Losing Quality — 3 Quick Methods
Whether you’re preparing visuals for high-resolution printing, restoring compressed JPEGs, or enhancing product shots, enlarging an image without losing quality requires precision. The following three methods, ranging from manual resizing to advanced AI image upscaling, show how to increase image resolution while maintaining edge definition, color accuracy, and fine detail.
1. AI Image Upscaler (Best for Maximum Detail Restoration)
- Pick an AI image upscaler tested for detail (we tested Aiarty Image Enhancer, Topaz Photo, HitPaw, etc.).
- Upload image and choose an appropriate model (portrait vs. detail/real photo) and scale (2×, 4×, or custom).
- Preview at 100% and tweak model/settings (reduce smoothing if skin looks plastic). Export as high-quality format like TIFF or PNG.
When to use: low-res photos, compressed JPEGs, or when you need to restore texture and fine detail for large prints. If your images have the similar issue, free download Aiarty Image Enhancer to enlarge them without losing quality now!
2. Manual Method with Photoshop (Best for Control & Print Work)
- Open image in Photoshop. Choose Image → Image Size.
- Enable Preserve Details 2.0 (Interpolation) and set the target dimensions or resolution (e.g., 300 DPI for printing).
- Apply selective Smart Sharpen or High Pass (blend mode: Overlay) on problem areas.
When to use: images where you need precise control (print, product photos). Photoshop preserves edges well but won’t “invent” missing texture.
3. Free Online Resizer (Best for Simple Needs)
- Use a reputable free site (ResizePixel, IMG2GO, or similar).
- Upload your image and choose a proportional scale (e.g., 200% or 400%).
- Select any “enhance” or “sharpen” option if offered, then download as PNG or high-quality JPG.
When to use: blog images, quick sharing, non-critical prints. Expect modest improvements but limited detail recovery.

FAQs about Enlarging Images without Losing Quality
This can be done with various AI image upscalers, like Aiarty Image Enhancer, Topaz Photo AI, Let’s Enhance and more. Take Aiarty Image Enhancer as an example:
- Load your image into the program.
- Drop down list of Upscale, and select 4K.
- Expand Output settings to select the output image format and specify the output folder path.
- Tap RUN button to start enlarging the image to 4K.
It’s quite a challenge. Enlarging pictures introduces new pixels, potentially blurring details. But advanced techniques can significantly reduce this quality loss, especially for smaller images.
You can increase image resolution intelligently using tools like Aiarty, Luminar Neo, or online platforms, potentially revealing more detail. Remember, it's always best to start with the highest quality image available, but these tools can more or less breathe new life into your existing JPEGs.
Sharper pictures, smaller squares! Images with high resolution have more tiny squares (pixels) packed in, making the picture look crisp and detailed. Lower resolution images have fewer, bigger squares, which can become obvious and blocky when the image is stretched.
If the image becomes blurred or pixelated, it's most likely a raster file. Unlike vector images, which can be scaled infinitely without losing quality, raster images get blurry or pixelated when enlarged. Think of vector images like building blocks that can be rearranged endlessly, while raster images are like tiny mosaics - stretching them messes up the picture.
