Every tool in this category processes images with your browser's Canvas feature. Your photos are never uploaded to a server, so there is no upload wait, and personal photos or scanned documents stay on your device.
Use compression for large photos, resizing when a site asks for specific dimensions, and conversion when a format does not fit. To print on paper, use Image Print Layout to place several pictures on one A4 page and save it as a PDF. To hide faces, licence plates or personal details in a photo, use Blur & Pixelate, and to put your name or logo on photos, use Watermark Images.
Crop and Blur & Pixelate edit one image at a time; the other tools handle multiple files at once, and when there are several results you can download them all together as a ZIP file.
