R2 Web

R2 Web is a browser-based file manager for Cloudflare R2 buckets. It is described as a pure client-side tool and a web-native Cloudflare R2 file manager, with all use happening in the browser. The interface is available in Simplified Chinese, Traditional Chinese, English, and Japanese, and it offers light, dark, and system-following themes as well as compact, standard, and spacious density settings.

The application includes settings for Account ID, Access Key ID, Secret Access Key, bucket name, custom domain, and bucket visibility, which can be set to public or private. It supports file name templates, including patterns based on names, hashes, and dates, and the template scope can be limited to images or applied to all files. Upload settings include selectable concurrent upload counts from 1 to 6. Compression can be turned off, set to local compression, or sent through Tinify, with balanced and maximum compression modes and a Tinify API key field.

R2 Web provides directory and file management, preview for common file types, drag-and-drop, paste, or click-to-upload input, and automatic compression during upload. It also offers one-click copying of external links and sharing configuration. The file view includes actions such as preview, download, QR code generation, copying links in URL, Markdown, and HTML formats, copying images, copying file paths, generating pre-signed URLs, changing type, renaming, copying, moving, and deleting. A configuration-sharing flow lets settings be migrated between devices by copying a link or scanning a QR code, with a warning that the link contains account credentials.
