Frequently asked questions
Are my images uploaded to a server?
No. The resizing happens entirely in your browser using the canvas API - your image never leaves your device, so it stays completely private.
Which formats are supported?
You can upload PNG, JPG, and WebP images, and export to any of those three. WebP usually gives the smallest file size for the web.
Does resizing reduce image quality?
Making an image smaller keeps it crisp; enlarging it past its original dimensions can look soft, since there's no extra detail to add. For the web, resizing down to the size you actually display is ideal.
Why does image size matter for SEO?
Large images slow your page down, and page speed is a ranking and user-experience factor. Resizing images to their display dimensions - and using WebP - cuts file size and speeds up load times.
What's the best image format for the web?
WebP usually gives the smallest file at good quality and is widely supported; JPG suits photos and PNG suits graphics with transparency. This tool exports all three.
