Make low-resolution photos clear online
Upscale images without distortion. Add pixels intelligently to boost clarity, fix blurry photos, and export higher-resolution pictures in seconds.
Use the OneImage upscaler to increase image resolution online without sacrificing detail. Instead of stretching pixels, the tool resamples your photo to add new pixels smoothly so edges stay crisp.
It's ideal for turning a low-resolution or pixelated picture into a sharper, high-definition result. Choose an exact target size or scale by 2x/4x to make your image clearer for printing, slides, or client deliverables.

Increase image resolution FAQ
What's the difference between resizing and upscaling?
Resizing can shrink or grow an image. Upscaling specifically increases resolution while resampling pixels to avoid blur. Use percentage values above 100% or larger dimensions to upscale cleanly.
How do I make an image less pixelated?
Set a higher target resolution with aspect ratio lock enabled. The tool smooths edges as it adds pixels, which reduces the blocky look of a pixelated image.
What size should I use for printing?
Aim for a higher pixel count that meets your printer's DPI. For example, doubling width and height often gives enough resolution for small posters or flyers.
Can this fix a blurry photo?
Upscaling cannot recover missing detail, but it can add resolution and reduce jagged edges so the image looks clearer when enlarged.
