EXACT PIXELS. SHARP EDGES.
Upscale pixel art locally with integer nearest-neighbor scaling. Preserve hard edges and transparency, then download a PNG without uploading.
A CLOSER LOOK
Pixel art needs an exact grid. This local upscaler repeats source pixels by an integer factor, keeping the original colors and avoiding AI-generated detail.
At 2×, each source pixel becomes a 2 × 2 block; at 4× it becomes a 4 × 4 block. There is no smoothing between neighbors. That keeps a deliberate staircase edge or one-pixel highlight intact. Fractional scaling would distribute source pixels unevenly, so this tool offers integer factors only.
Use PNG when the source has transparent areas. The tool downloads PNG and processes the image in your browser without sending it to a server. Keep the original sprite as your editable master; an enlarged copy is useful for previews, presentations or a larger pixel-grid export.
A still sprite sheet can be enlarged as a single image, but the tool does not rearrange frames or create a game-engine atlas. GIF animation and sprite metadata export are not supported. For a game, you may prefer keeping the original assets and choosing nearest filtering in the engine so resolution stays independent from display size.
GOOD QUESTIONS
No. It performs deterministic nearest-neighbor scaling in your browser. It adds no generated texture and uses no processing credits.
No. This release supports still PNG, JPG and WebP input and a PNG download. Animated inputs are not offered.
JPEG already introduces compression artifacts. Use a lossless PNG master where possible; enlargement cannot undo an earlier lossy export.
