Upscale images with AI-powered super-resolution
Turn a small or low-resolution photo into a sharp, print-ready image. The AI model reconstructs missing detail — textures, edges, and fine patterns — rather than stretching existing pixels. Choose 2x for web use or 4x for large prints and posters.

2x and 4x upscaling
Double or quadruple the pixel dimensions of any photo. A 500 x 500 px image becomes 1000 x 1000 at 2x or 2000 x 2000 at 4x, with genuine detail synthesized by the AI model.
Detail reconstruction
Unlike bicubic interpolation, the AI model predicts and generates fine textures — hair strands, fabric weave, brick patterns — producing output that looks naturally sharp at the target resolution.
Face enhancement
A dedicated face-detection pass refines facial features during upscaling: sharper eyes, smoother skin, and clearer jawlines, without the plastic look of aggressive sharpening.
Noise reduction
The model suppresses JPEG compression artifacts and sensor noise during the upscale pass, delivering cleaner output than the original even at 1x magnification.
How to use
Upload your image
Drag a JPEG, PNG, or WebP file into the upscaler. The tool supports files up to 25 MB with a maximum input resolution of 4000 x 4000 px.
Choose upscale factor
Select 2x for web-sized output or 4x for print-quality enlargement. The estimated output dimensions display below the selector.
Preview and compare
Use the side-by-side slider to compare the original and upscaled versions. Zoom in to check fine detail before downloading.
Download
Save the upscaled image as a high-quality JPEG or lossless PNG. The file is processed locally and never leaves your device.

Common questions
How is AI upscaling different from regular resizing?
+
Standard resizing uses interpolation, which averages neighboring pixels and produces blurry results. AI upscaling uses a trained neural network to predict and generate the missing detail, producing output that looks naturally sharp at the larger size.
Can I upscale a screenshot or graphic with text?
+
The model is optimized for photographs. It can upscale screenshots, but text edges may show slight softening. For pixel-perfect text, export the original at a higher resolution when possible.
Will the upscaled image be large enough for a poster print?
+
A 1000 x 1500 px photo upscaled 4x becomes 4000 x 6000 px — enough for a sharp 13 x 20 inch print at 300 DPI. For wall-sized prints, start with the highest-resolution source you have.
Already upscaled? Make it even better.
AI Enhance goes beyond upscaling — it corrects exposure, boosts color accuracy, and removes remaining artifacts. Chain the two tools for maximum quality from a low-resolution source.
