Get higher-quality, sharper, and more detailed images
Turn low-resolution images into high resolution in just 3 seconds. LightX AI Photo Upscaler not only increases image resolution but also preserves and improves details. It improves textures, edges, and patterns, making images sharper and clearer. It works well with low-light or compressed images.
Zoom in without pixelation
If you notice, images appear pixelated when zoomed in too much. This happens because they have a limited number of pixels. LightX AI HD upscaler is an image resolution enhancer that generates new pixels within your image. This ensures sharp details even when zoomed in.
Blurry text in photos? Make them clear & readable
This is especially great for images with text! When you upscale images that contain text (even in small sizes), it makes them clearer and more readable. Whether it's a scanned document, logo, subtitle, or caption, faded or blurry text will become sharp and smooth again.
Make images ready for big-size printing!
Printing without upscaling comes with several issues, from pixelation and loss of fine details to faded and washed-out colors. LightX intelligently enlarges images, adds missing details, and smoothens edges. It also fixes washed-out colors and enhances vibrancy, ensuring excellent print quality at higher DPI.

Frequently Asked Questions
2x upscaling doubles the image pixels, while 4x upscaling increases them four times. If your image is very low resolution, we recommend upscaling 2x first, then 2x again, instead of going straight to 4x. That's because at 2x upscaling, the tool has enough data to enhance details smoothly. But at 4x, the AI has to guess more details, which might create artificial textures.
