About this tool
Normal image resizers blur pixel art into mush because they blend neighboring pixels. This upscaler multiplies every pixel into a clean block instead, so a 16 × 16 Minecraft texture or a 32 × 32 sprite becomes a sharp 256 or 512 pixel image for thumbnails, wikis, documentation, and social posts.
Whole-number factors keep the grid exact. Use 4× to 8× for previews and 16× for print or wallpapers. Transparency is preserved, and you can switch to smooth scaling if the image is a photo rather than pixel art.

Questions
Why does my pixel art look blurry when I resize it elsewhere?
Most tools use bilinear or bicubic interpolation, which averages neighboring pixels. Nearest-neighbor scaling copies each pixel into a solid block, keeping the art crisp.
Can I upscale a photo with this?
You can, but photos look blocky with crisp scaling. Switch the scaling option to smooth, or use the Resize Image tool.
Does it work with transparent PNGs?
Yes. Transparency is kept exactly.
