PicRover is a tool designed for collecting webpage images, batch downloading, and local image organization. You can browse webpages in multiple independent workspaces, recognize image resources on a page, choose the images you need by group, and save them reliably into local folders. Highlights Reliable Image Recognition and Downloading ⊙ Recognize image resources on webpages as much as possible, and intelligently group them by webpage structure so you can find the images you want more easily. ⊙ Automatically detect and navigate to the next page, then continue recognizing and downloading target images. Manual next-page calibration is also supported. ⊙ Recognize similar links and queue them for downloading in a workspace, which is especially useful for gallery lists and image collection pages. ⊙ Customize recognition mode, file naming rules, navigation/download timeout, retry count, URL rewrite rules, image size filters, download concurrency, and more for each website. Multiple Workspaces for Higher Efficiency ⊙ Use multiple independent workspaces, each keeping its own webpage state, browsing history, and task progress. ⊙ Long-press a link or image to open it in the current workspace, a new workspace, or another workspace. You can also open and download directly. Immersive Image Playback ⊙ Full-screen gallery browsing, vertical comic reading mode, and slideshow playback are supported. ⊙ Multi-grid playback lets you view up to 25 images on one screen at the same time, with face-aware motion animation for a smoother continuous viewing experience. ⊙ Manage images by group and favorite images, making it easier to organize your collections. Fast and Convenient Image Processing ⊙ Merge multiple image sets and batch save images to Photos. ⊙ Share image sets as ZIP or PDF packages. ⊙ Batch image processing supports quality presets, resizing, JPEG output, and OCR-based watermark cropping. Processed results are saved as new image sets while the original images are preserved. Membership and Download Quota PicRover is free to download and includes basic features. Free users can save a limited number of images. Premium members can unlock more download quota, export features, batch processing, multi-image playback, similar-link copying, and more. Subscription and purchase details are subject to the App Store page and in-app display. Subscriptions can be managed or canceled through your App Store account. Please comply with website rules, copyright requirements, and applicable laws when downloading and using webpage images.
