Frequently asked questions

How do I resize an image to exact pixels?

Choose “Width / height”, type the pixel size you need, and download. Leave “Keep aspect ratio” on and fill in just one dimension to scale the other automatically.

Will resizing stretch or distort my image?

Not if “Keep aspect ratio” is enabled (the default). Turn it off only if you deliberately want to squash an image to exact dimensions.

Are my images uploaded to a server?

No. Unlike most online converters, nothing is uploaded to a server. The conversion happens entirely inside your web browser using your device's own processing, so your images never leave your computer or phone. You can even disconnect from the internet after the page loads.
