FAQ
What image format should I use for SEO?
WebP is recommended for website images as it offers the best compression-to-quality ratio and is supported by all modern browsers. Use PNG for favicons and icons that need transparency. JPG works well for photographs and complex images.
Will my images be stretched or distorted?
The tool resizes your image to fit the exact dimensions selected. If the aspect ratio of the target size differs from your original image, the image will be stretched to fill the dimensions. For best results, start with a high-resolution source image and consider using an image with an aspect ratio close to your target sizes.
Is my image uploaded to a server?
No. All processing happens entirely in your browser using the HTML5 Canvas API. Your images never leave your device, making this tool completely private and secure.
Why do I need so many different image sizes?
Different platforms and devices require specific image dimensions. Facebook uses 1200x630 for link previews, Twitter uses 1200x675 for large cards, Google requires specific sizes for Discover and structured data, and browsers need multiple favicon sizes. Using correctly sized images improves your SEO, social sharing appearance, and overall user experience.
What quality setting should I use?
For most use cases, 85% quality offers an excellent balance between file size and visual quality. For favicons and small icons, use PNG format for the crispest results. For large hero images and social media, 80-90% JPG or WebP quality is ideal.
What is the recommended source image size?
Start with the largest image you have, ideally at least 1920x1080 pixels. Upscaling small images to larger sizes will result in blurry or pixelated output. A high-resolution source ensures all generated sizes look sharp and professional.
