Frequently Asked Questions about image resizing
What image formats can I resize?
JPG, PNG, WebP, and GIF are all supported. The output will be in the same format as the input (JPG stays JPG, PNG stays PNG).
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 isn't stretched or distorted.
Can I enter just one dimension?
Yes. Enter only width or only height — with aspect ratio enabled, the other dimension will be calculated automatically.
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.
