No. All image processing happens entirely in your browser. Your images never leave your device, making LaiUse one of the most private ways to work with images online.
JPG, PNG, WebP, GIF, BMP, and TIFF are all supported. For best results, use WebP for web images and PNG for images that need transparency.
No hard limit. Since processing happens in your browser, the only limit is your device memory. For very large images, we recommend using a modern browser with at least 4GB of RAM.
