Quick answers about supported image formats, HEIC uploads, online resizing, and export options.

Which image formats can I upload?+

You can upload JPG, JPEG, PNG, WebP, AVIF, HEIC, and HEIF images from your device, plus supported public image links.

What formats can I export?+

You can export resized images as WebP, JPG, PNG, or AVIF so they work well for websites, social posts, stores, and downloads.

Can I use it without creating an account?+

Yes. Guest uploads can work right away when they are enabled, while signing in adds saved history, dashboard access, and plan-based limits.

Can I keep aspect ratio locked while resizing?+

Processed assets are stored by the app and exposed through safe result and download routes rather than raw server file paths.
