Cleaner than a basic resize

Stepped resampling plus sharpening avoids the blurry, mushy look of stretching an image in one jump.

How it works

Enlarging an image by just stretching it makes it blurry. This tool enlarges in steps and sharpens the result so edges stay as crisp as possible at the new size. Upload your picture, pick 2× or 4×, and preview the before/after. It's ideal when you need a bigger version of a photo or graphic for print or a large screen and don't want the soft, pixelated look you get from a basic resize. Everything happens in your browser and downloads at full resolution.

Frequently asked questions

Will the bigger image be blurry?

Far less than a normal resize — stepped resampling and sharpening keep it as crisp as possible, though it can't add detail that wasn't captured.

What's the biggest size I can get?

Up to 4× the original, capped at roughly 4096px on the longest side to stay within browser memory.

Is there a file-size or count limit?

No per-image fee or count limit — it's free and runs locally.
