How do I fix blurry AI pixel art online?

Upload a PNG, JPEG, or WebP image, leave Pixel size on Auto-detect, and start with 16 palette colors. Select Fix Pixel Art, then drag the comparison slider to inspect outlines and small details. If the grid looks wrong, choose Set manually and adjust the source pixels per grid cell. Download the PNG once the result suits your sprite. Severe blur can still require manual editing.

Which image formats and sizes can I use for grid repair?

The fixer accepts PNG, JPEG, and WebP files up to 15 MB, with each side between 2 and 2048 pixels. GIF and animated files are not supported by this page. The tool processes one image at a time and exports a PNG. Output dimensions follow the repaired grid unless you set a square output size, so a large source image may become a much smaller sprite.

Can a pixel art fixer remove every mixel in a sprite?

Grid repair can reduce mixels when a sprite has a recognizable underlying grid, but it cannot guarantee a complete repair. Mixels are blocks that appear at different pixel sizes in the same image. Auto-detect may struggle when those sizes conflict. Try a manual cell size, then check eyes, fingers, and thin outlines in a pixel editor before using the result.

Can I clean an entire sprite sheet or animated GIF at once?

This tool is optimized for static, single-sprite images to ensure accurate pixel grid detection across the entire canvas. If you have an AI-generated sprite sheet, slice it into individual frames or character poses first, run each through the fixer, and reassemble them in your game engine or pixel editor. Animated GIFs are not supported directly.

What changes when you fix AI-generated pixel art?

Compare three AI-generated source images with PNGs produced by this fixer. Drag the divider or switch to a side-by-side view. Each example lists its actual repair settings and dimensions. Previews are enlarged; downloads keep the original file sizes.

Character sprite: inspect the outline

The archer shows how grid repair changes a character silhouette. Compare the bow, hood, and small face details. At 16 colors, some neighboring shades merge, so review the result before adding it to a sprite sheet.

Item icon: compare highlights and colors

This newly generated mana crystal has bright facets and a detailed bronze base. The 16-color repair simplifies the palette and rebuilds the grid. Compare the small cyan highlights and the pedestal before choosing your own color count.

Environment prop: check the small details

The woodland cottage uses a 32-color repair to retain more of its roof, ivy, and stone shading. Inspect the window, bottles, and roof tiles in both views. Automatic grid detection changes the output dimensions, so check the result at the size your game will display.

What does the AI pixel art fixer repair?

AI-generated pixel-art scene with a green-hooded traveler, woodland cottage, workbench, potion, crystal, and treasure chest — AI-generated source artwork illustrating character, item, and environment assets. This scene is an illustration, not a repaired result.

Sprite Flow's AI pixel art fixer rebuilds existing pixel-style images on a consistent grid. The repair process estimates the source pixel size, reduces the color palette, and resamples each grid cell into an output pixel. This can clean uneven outlines, blended anti-aliasing artifacts, and mixed-size pixels in AI-generated sprites. Use the pixel art cleaner for character sprites, item icons, or individual tiles generated with tools like Midjourney, Stable Diffusion, DALL-E, or RetroDiffusion that have a recognizable pixel structure. A photo-to-pixel-art converter creates a pixelated style from an ordinary image. This fixer instead works with an existing pixel pattern. It does not generate a new character or reconstruct missing details. Image repair is free and runs entirely in your browser without an account or credits. Your selected image is never uploaded to a server. The result is a clean PNG at the repaired resolution, ready for your game engine or sprite editor. Review small details and palette changes before using the asset in your project.

How can you clean uneven pixels and blurry edges?

Align off-grid pixels with automatic or manual sizing

Start with auto-detect to estimate the grid behind an enlarged sprite. If the result looks too coarse or too detailed, set the source pixels per grid cell manually. An 8-pixel setting describes the source cell size, not an 8 × 8 output image.

Rebuild mixed-size pixels on one grid

Mixels are pixel-like blocks with inconsistent sizes inside one image. Grid resampling turns each detected cell into 1 output pixel to make those blocks more consistent. A sprite with several competing grids may still need manual edits around faces, outlines, or narrow objects.

Reduce blended edge colors with a smaller palette

Choose 8, 16, 32, or 64 palette colors to reduce shading and blended edge colors. Start at 16, then try 32 or 64 if small highlights disappear. Palette reduction can change the original colors; this page does not offer a custom palette or a grid-only repair mode.

Compare the repair and download its native PNG

Drag the before-and-after slider to inspect the same sprite, then check the reported output width and height. The preview is enlarged for comparison. Download PNG saves the actual repaired dimensions; use nearest-neighbor scaling when you need a larger display size.

Questions about fixing AI pixel art

Sprite Flow's AI pixel art fixer is free to use without signing in or spending credits. Image repair runs locally in your browser, and the selected image is not uploaded for processing. The fixer uses the open-source Pixel Snapper algorithm to repair existing artwork. It does not send a prompt to an AI image generator.

Pixel grid repair estimates the pixel pattern and rebuilds the image on that grid while reducing its palette. Ordinary resizing changes image dimensions without identifying that pattern. Nearest-neighbor scaling is useful for enlarging an already clean sprite, but it also enlarges existing artifacts. This fixer can reduce blended anti-aliasing colors, but it cannot restore every lost edge or preserve every shade.

Import the downloaded PNG into your game engine or pixel editor and check its actual dimensions before setting the sprite scale. Use nearest-neighbor filtering to avoid adding blur. Inspect the background, palette, and small details at your intended display size. Grid repair does not remove a background or change the original artwork’s license. A sprite sheet may need slicing adjustments if its dimensions change.
