Image Resizer for Game Textures: 64, 256, 512, 1K and 2K Presets
Drop in an image, choose a game-friendly size and download a PNG. It tells you when your original is not a power of two and keeps pixel art sharp with nearest-neighbour scaling.
Game engines prefer power-of-two sizes (64, 256, 512, 1024, 2048) for texture compression and mipmaps. Processing happens in your browser.
Upload an image to resize it.
Why power-of-two sizes
Many engines and GPUs compress and mipmap textures best at sizes like 256, 512, 1024 and 2048. Non-power-of-two images may be padded or resized on import, wasting memory or quality.
Use nearest-neighbour scaling for pixel art so edges stay hard, and smooth scaling for photos and painted textures. Check texture density with the texel density calculator.
When to use it
Shrinking photo textures
Bring a 4000-pixel photo down to 512 or 1024 before importing it, so the project stays light.
Pixel art upscales for store pages
Scale sprites by whole numbers with nearest-neighbour for itch.io and Steam screenshots without blur.
Fixing odd sizes
Pad or resize textures to powers of two so they compress and mipmap properly on every platform.

Questions
It depends on the object on screen. Small props use 64 to 256, characters 512 to 1024 and hero assets 2048. Keep a consistent density across a scene.
No. It is resized in your browser.
It was scaled with smoothing. Use nearest neighbour, and set point filtering in the engine.
Modern engines accept other sizes, but power-of-two textures compress better, support mipmaps on every platform and tile without problems. They remain the safe choice.
Stores and social sites resize small images with smoothing, which blurs pixel art. Upscaling by 4x or more first keeps the pixels crisp.
