Resize image FAQ

Is my image uploaded when I resize online?

No. ResizeImg resizes with Canvas in your browser. Your file never leaves your device.

How is ResizeImg different from ImageToSize?

ResizeImg sets exact width × height in pixels. ImageToSize compresses to a target file size in KB—complementary tools.

Can I export a multi-size favicon.ico?

Yes. Choose ICO. For square outputs 48×48 or larger, ResizeImg packs 16, 32, and 48 into one .ico. Favicon presets select ICO automatically.

Does enlarging an image make it sharper?

No. Upscaling cannot invent true detail. Start from a larger source when quality matters.

Which formats can I upload and download?

Upload JPG, PNG, WebP, or GIF. Export JPG, PNG, WebP, or ICO.

How do I resize without stretching?

Keep aspect ratio locked (default on the home tool), or open the keep-aspect-ratio guide. Unlock only when you need exact pixels that may stretch.
