Frequently Asked Questions

256×256 pixels is Small (256×256). It's commonly used for desktop icons, small app icons and favicons. At 72 DPI (standard screen), this is roughly 4×4 inches.
Cover fills the exact 256×256 frame by cropping from the edges — best for social media profiles. Contain fits the whole image inside 256×256 with padding if needed — best for product images. Stretch forces exact dimensions but may distort the image.
Downscaling (making the image smaller) has minimal quality impact. Upscaling to 256×256 if the original is smaller may reduce sharpness — use the AI Upscaler tool for best upscaling results.
You can output as JPEG (best for photos), PNG (best for graphics with transparency), or WebP (best compression for web use).
Downscaling reduces file size with minimal quality impact. Upscaling beyond the original dimensions can cause blurriness — use the AI Upscaler for enlarging images with best results.
Enable "Lock aspect ratio" before resizing to prevent stretching. This ensures width and height scale proportionally. For social media presets, Pixaroid automatically crops to fill the exact frame using Cover mode — you can switch to Contain mode to show the full image with letterboxing instead.
For standard web use, aim for images under 150KB and no wider than 1600px. Hero images can be up to 1920px wide. Use WebP format for the best quality-to-size ratio. Images above 1MB significantly slow page load speed and hurt SEO rankings.
