Frequently Asked Questions about image resizing
What image formats can I upload?
JPG, PNG, WebP, GIF, BMP, ICO, and SVG are all supported as input. You can also import an image directly from a URL using the Import from URL option below the upload zone.
What output formats are available?
You can export as JPG, PNG, WebP, ICO (for favicons and app icons), or BMP. Select your desired format using the format buttons before converting. The Auto option keeps the same format as your source image.
How do I create a favicon (.ico) from my logo?
Upload your logo (PNG or SVG recommended), set the dimensions (common sizes: 16×16, 32×32, 48×48, or 256×256), select ICO as the output format, and click Resize. The downloaded .ico file can be placed directly in your website root or Next.js app/ directory.
What does maintain aspect ratio mean?
When enabled, the image is scaled proportionally — if you enter only a width, the height is calculated automatically so the image is not stretched or distorted. A live preview of the exact output dimensions is shown before you convert.
Will resizing reduce the file size?
Usually yes — smaller images have fewer pixels and therefore smaller file sizes. The exact reduction depends on the image content and target dimensions.
Are my images kept private?
Yes. The entire resize operation runs in your browser using the Canvas API — your images are never uploaded anywhere.
