Why use Image Enlarger?

Crystal Clear Smoothing

This tool utilizes your browser's highest quality internal scaling algorithms (often bicubic or Lanczos based on the browser engine) to blow up low-res images while attempting to reduce hard pixel artifacting.

Pixel Art Support

Uncheck the "High-Quality Smoothing" option to enforce Nearest-Neighbor scaling. This is the absolute mathematically perfect way to cleanly upscale retro 8-bit or 16-bit sprites without making them blurry.

How to enlarge an image?

Upload

Drag your small or low-res photo into the upload area.

Pick a Multiplier

Select 2x, 4x, or 8x to determine how many times larger you want the final resolution to be. Warning: 8x on an already large photo can easily exhaust your computer's RAM!

Process & Save

Click Enlarge to compute the new high-resolution image locally via HTML5 standards, then immediately save the result.
