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.

Need a smaller file size (KB) instead?
