CloudShare: S3 File Sharing

Your bucket. Your links.

CloudShare turns your S3-compatible bucket into a file-sharing tool for iPhone and iPad. Upload photos, videos, and documents, then copy or share a link. Use Cloudflare R2, Amazon S3, or another compatible provider with your own storage account.

SHARE FROM YOUR FAVORITE APPS
Choose CloudShare in the iOS share sheet to queue files from Photos, Files, and other apps. You can also select photos, videos, and files directly inside CloudShare.

UPLOAD IN THE BACKGROUND
Queue transfers and return to what you were doing. Check upload activity in the app and retry failed transfers. Large files use multipart uploads automatically, and retries can reuse parts already uploaded while the provider's upload session remains available.

CHOOSE HOW YOU SHARE
Create expiring private links, or use public links with a domain already connected to your public bucket. Set private-link expiry to one hour, 24 hours, or seven days. Anyone with a private link can access the file while the link remains valid; temporary storage credentials may shorten its lifetime.

BROWSE YOUR BUCKET
View files in your connected bucket, including files uploaded elsewhere. Load more results as needed, search loaded files, and generate links for existing objects.

KEEP CONTROL OF YOUR STORAGE
Files upload directly to the provider you configure. Your connection settings and credentials are stored in this device's Keychain. Choose an upload folder and connect an optional public domain.

BEFORE YOU START
CloudShare requires your own S3-compatible bucket, HTTPS endpoint, and API credentials with the necessary listing, upload, and read permissions. Cloud storage is not included. Your provider's storage, request, and bandwidth charges may apply.

Background transfers are scheduled by iOS and may be delayed by network, power, or system conditions. Force-quitting the app can interrupt transfers. Large uploads require enough free device storage to prepare files, and your provider's object-size limits apply. Folder uploads are not supported; compress folders into ZIP files first.

Public links require an existing public bucket/domain setup. CloudShare does not configure DNS, make private files public, or administer your storage account.
