iSave is a browser based tool for saving publicly accessible TikTok videos to a device. Users paste a TikTok video URL into the site, select the download option, and save the available video as an MP4 file. The service may provide a high definition version without a watermark, depending on the video available through the public link. To use iSave, a user copies a video link from TikTok, pastes it into the iSave page, and downloads the prepared file for offline viewing. The service does not require an account, subscription, or app installation. It is intended for personal offline copies, and users are advised to respect creators’ rights and TikTok’s terms. iSave runs in a web browser and is described as compatible with iPhone, Android, Windows, and macOS devices. It can be used with browsers including Google Chrome, Mozilla Firefox, and Microsoft Edge. On iPhone, downloaded files can be accessed through Safari Downloads or the Files app; on other devices, they are typically saved to the browser’s Downloads location or a selected folder.
