No blur
Nearest-neighbor enlargement keeps hard pixel edges when the chosen size stays within the output limit.
Language: English (UK)
Resize pixel art without blur
Enlarge pixel art with 2×, 4×, or 8× nearest-neighbor presets. Each output dimension is capped at 8192 pixels.

Why use this instead of a normal image resize?
Smooth interpolation can blur pixel edges. Choose 2×, 4×, or 8× nearest-neighbor enlargement here. Keep both scaled dimensions at or below 8192 pixels: each axis is capped independently, which can change the aspect ratio and exact scaling.

A practical example
Resize the demo without blurred edges
Use a concrete input, inspect the output, and check the current limits before choosing your next step.
Example input
Use the transparent 128 × 64 demo PNG below as the source.
What to check
- Download the demo sheet and choose it in the resizer.
- Select 4×. The expected output is 512 × 256 pixels; one source pixel occupies a 4 × 4 block.
- Inspect diagonal edges and transparent areas, then download the PNG.
Expected output
The 4× preset produces a crisp 512 × 256 copy of this 128 × 64 source.
Current limits
The available presets are 2×, 4×, and 8×. Output width and height are each capped at 8192 pixels, so oversized inputs can lose the requested scale or proportions.

01 / WHY IT WORKS
Made for production, not just previews.
Integer presets
Choose 2×, 4×, or 8×. Outputs above 8192 pixels on either axis are capped, which can change the aspect ratio.
Local processing
Files stay in your browser and transparency remains intact.
From source to clearly labeled output.
Upload art
Choose a PNG, WebP, or JPG sprite, icon, tile, or scene.
Choose a scale
Pick an integer multiplier and inspect the actual output dimensions.
Download PNG
Export a crisp scaled copy without smoothing.
03 / FAQ
Clear terms before you build.
Why use integer scaling?
Whole-number multiples give every source pixel the same output footprint, preventing uneven edges.
Does it preserve transparency?
Yes. Transparent PNG and WebP inputs keep their alpha channel in the PNG output.
What happens if the scaled image exceeds 8192 pixels?
Each output dimension is independently capped at 8192 pixels. That can change the aspect ratio and break exact integer scaling. Choose a smaller preset or a smaller source so both scaled dimensions stay within the limit.
Is my image uploaded?
No. Resizing runs entirely in your browser.
