Best Image Format for Pixel Art
PNG is the only acceptable format for pixel art. Every pixel in pixel art is intentionally placed, and any lossy compression fundamentally destroys the art by blurring, shifting, or blending individual pixels. There is no situation where JPG, WebP lossy, or any other lossy format is appropriate for pixel art. The format question for pixel art is not JPG vs PNG; it is PNG, period.
Pixel art is created at extremely small canvas sizes, often 16x16, 32x32, 64x64, or 128x128 pixels. Each pixel is a deliberate design decision. When displayed, pixel art is scaled up (often 2x to 8x) using nearest-neighbor interpolation that preserves the crisp pixel grid. Lossy compression not only blurs the original pixels but also destroys the clean edges that nearest-neighbor scaling depends on.
Here is everything you need to know about saving, scaling, and sharing pixel art correctly.
Why PNG Is Non-Negotiable
PNG is a lossless format that preserves every pixel exactly as designed. For pixel art, this is not a preference; it is a requirement. Even mild JPG compression at quality 95 introduces artifacts around every color boundary in the art.
At pixel art's small canvas sizes, PNG files are tiny anyway. A 64x64 pixel art sprite with 16 colors is typically under 2KB as PNG. There is zero reason to use a lossy format when the lossless version is already smaller than most favicons.
- Lossless: every pixel preserved exactly as created.
- Transparency: essential for sprites, characters, and assets that appear on varied backgrounds.
- Indexed color: PNG supports indexed color mode, which further reduces file size for limited-palette pixel art.
- Tiny file sizes: pixel art PNG files are measured in kilobytes, making compression irrelevant.
- Universal: every platform, game engine, and social media site accepts PNG.
Scaling Pixel Art Correctly
The most common mistake when sharing pixel art is scaling it with the wrong interpolation method. When you resize pixel art from 32x32 to 256x256 for display, you must use nearest-neighbor interpolation. Any other method (bilinear, bicubic, Lanczos) smooths the pixel edges, destroying the art.
Scale by exact integer multiples: 2x, 3x, 4x, 6x, 8x. Non-integer scales (like 2.5x or 3.7x) distort the pixel grid because pixels cannot be split. After scaling, export as PNG. Never scale and save as JPG.
- Always use nearest-neighbor interpolation when scaling up.
- Scale by integer multiples only: 2x, 3x, 4x, 8x.
- Export the scaled result as PNG.
- Keep the original small-canvas file as your master. Scale only for display/sharing.
Sharing on Social Media
Social media platforms are the biggest threat to pixel art quality. Twitter/X, Instagram, and Facebook all recompress uploaded images as JPG, destroying pixel art in the process. Knowing each platform's behavior helps you minimize damage.
Twitter/X preserves PNG quality for images under 900 pixels on the longest side. Scale your pixel art to at least 512x512 (or equivalent) using nearest-neighbor before uploading. Images under 900px on the longest side generally avoid recompression to JPG.
- Twitter/X: upload PNG at 512x512 or larger (but under 900px longest side). Larger images get JPG-compressed.
- Instagram: always converts to JPG. No way to avoid it. Scale to 1080px wide for least compression.
- Discord: preserves PNG quality. Upload at any size.
- DeviantArt, ArtStation, itch.io: preserve PNG quality. These are the best platforms for pixel art.
Pixel Art for Games
Game engines universally prefer PNG for sprite sheets and tile maps. PNG's transparency support and lossless quality make it the standard format for all 2D game assets.
Export sprite sheets as PNG with transparent backgrounds. The game engine handles the rendering, scaling, and palette mapping at runtime. For particularly large sprite sheets, some engines support texture atlases with specialized formats, but the source art should always be PNG.
- Sprite sheets: PNG with transparent background. No padding artifacts.
- Tile maps: PNG at 1x scale. The engine handles scaling.
- Character animations: PNG sprite strips or individual frame PNGs.
- Unity, Godot, GameMaker, RPG Maker: all import PNG natively.
- Set texture filtering to Point/Nearest in the game engine to prevent blurring.
GIF vs PNG for Animated Pixel Art
For animated pixel art, the choice is between GIF and APNG (animated PNG). GIF has universal support but limits you to 256 colors per frame and only 1-bit transparency (fully transparent or fully opaque). APNG supports full 24-bit color and partial transparency but is not supported everywhere.
For simple animated pixel art with limited colors, GIF works fine and has the broadest compatibility. For complex animations with many colors or semi-transparency, APNG is the technically superior choice. Export individual frames as PNG regardless, and assemble the animation in your preferred format.
Frequently Asked Questions
Can I save pixel art as JPG?
No. JPG compression destroys pixel art by blurring individual pixels and creating artifacts at color boundaries. Even high-quality JPG settings visibly degrade pixel art. Always save as PNG.
How do I scale pixel art without blurring it?
Use nearest-neighbor interpolation and scale by exact integer multiples (2x, 3x, 4x, etc.). In Photoshop, choose Image > Image Size > Nearest Neighbor. In GIMP, use Scale Image > None. In Aseprite, export with the scaling option set to an integer multiple.
Why does my pixel art look blurry on social media?
Most social media platforms recompress uploaded images as JPG and may apply smoothing during resizing. Scale your pixel art to a reasonable display size (512x512+) using nearest-neighbor interpolation before uploading. Some platforms like Twitter preserve PNG under certain size thresholds.
What is the best software for creating pixel art?
Aseprite is the most popular dedicated pixel art editor, offering animation support and proper pixel-level tools. Alternatives include Piskel (free, web-based), GraphicsGale (free), GIMP (with pixel art configuration), and Photoshop (with pencil tool at 1px and nearest-neighbor scaling).
