Connect Buckets Through S3-Compatible Endpoints
Simple S3 Browser starts with a focused connection workflow for S3-compatible object storage. Users enter a Bucket Name, Endpoint, Region, Access Key, and Secret Key, then tap Connect to reach the storage service they need. This setup fits providers such as AWS S3, MinIO, Cloudflare R2, Wasabi, and Storj without making each one a separate app.
Multiple endpoints and buckets can be kept as separate profiles, so a personal archive, work bucket, or self-hosted service is easier to switch between. The optional biometric setting adds a local unlock step for a bucket, giving people another way to protect access when the phone is shared or used on the move.
Navigate, Preview, and Manage Remote Files
Once a connection is available, the app is designed to turn remote object storage into a more familiar file workspace. Folder navigation, pagination, multi-select, copy and move actions, and folder creation help users locate and arrange objects without relying on a desktop browser.
Simple S3 Browser also supports uploading files or folders, downloading items, and sharing them with other Android apps. Built-in viewers and players extend the workflow to images, audio, video with subtitles, PDF, Markdown, EPUB, common office documents, and popular archives, so users can inspect many stored files before deciding what to move or send onward. That flexibility keeps common storage tasks in one place.
Search Large Buckets and Track Transfers
Large buckets benefit from a global search that works across folders with an on-device index. After indexing is ready, users can look for objects by name instead of opening one directory at a time, which is helpful for media libraries, project exports, backups, and long-running archives. The app can handle buckets with more than one million objects.
A dedicated Transfers area keeps uploads and downloads visible while work continues. Pause and resume controls, throughput and ETA information, and progress that can persist across app restarts make longer file operations easier to monitor. These tools are especially useful when a mobile connection is less convenient than a desktop session but the storage task still needs to finish.
Biometrics, Sharing, and Daily File Handoffs
Mobile storage work is often about quick handoffs rather than full administration. With file sharing, previews, and several saved bucket profiles, users can open a document, listen to an audio file, inspect an image, or pass an object to another Android app from the same storage workspace.
The connection form keeps the essential S3 details visible, while the biometric option supports people who want a local check before returning to a bucket. Simple S3 Browser is a practical fit for developers, self-hosters, content teams, and anyone maintaining S3-compatible storage while away from a larger workstation. It favors a direct, task-focused workflow over a crowded dashboard.
