Frequently asked questions

Is BannerCrop AI free?+

Yes. You can crop, upscale and optimize images and download them for free — no watermark, no account, and no install.

Are my images uploaded to a server?+

No. Every tool runs entirely in your browser, so your images never leave your device. That makes it fast and private by default.

Is it a good free Canva or Photoshop alternative for banners?+

For the specific job of resizing and cropping images to exact banner sizes, yes — it's faster and simpler. There's no sign-up, no learning curve, and AI centers your subject automatically. For full graphic design you'd still use Canva or Photoshop.

Which banner and image sizes are supported?+

We include 25+ ready presets — CMS banners and galleries, website heroes, Facebook, Instagram, LinkedIn, YouTube, X/Twitter, Pinterest, TikTok, Google Ads and more — plus any custom pixel size you type.

What file formats can I export?+

PNG, JPEG, WebP and AVIF, each with quality control and a live file-size readout so you can balance quality and weight.

Do I need to install anything?+

No. BannerCrop AI works in any modern browser on desktop, tablet or phone — nothing to download.
