How it works
Three steps, and the second one is just uploading as you always have.
Connect the accounts you have
Sign in with Google, then add Box, pCloud, Koofr or any S3 bucket from Storage. Each one adds its free space to your drive.
Upload as usual
Storsum sends each file to the account with the most room, encrypted on the way, and keeps your folders as you made them.
Use one drive everywhere
The same folders and files on the website, your phone and your computer. Search, share and move them as if they were in one place.
Your space, added up. Your files, kept private.
Connect the accounts you already have. Storsum shows how full each one is, puts every upload where it fits, and keeps the lot in one place.
Uploads go where there is room
Each file lands on the account with the most free space, or on the one you pick. You never juggle quotas again.
Encrypted before it leaves
Files are encrypted on the way to your provider unless you say otherwise, so Google or Box only ever hold scrambled data.
Your Google Drive comes along
Import from Drive shows everything you already keep there, in its own folders, and Sync keeps it up to date.
One set of folders, one search
Folders, search, filters and previews work across every account, as if it were one disk.
Share by link or by invite
Send a link anyone can open, or invite another Storsum user to a file or a whole folder.
Move files between accounts
Running low on one account? Move its files to another without downloading anything.
An API for your scripts
Create, read, rename and delete files and folders with an API key you can limit to what a script needs.
Drag and drop
Drop files onto the Files page on the website, or anywhere on the Windows and Linux app, to upload them.
Works with the storage you have
Six providers with free plans, and any bucket that speaks S3. Connect as many accounts of each as you like.
Box
10 GBBox’s free plan takes files up to 250 MB each.
pCloud
Up to 10 GBUS and EU accounts both work.
Koofr
10 GBA European provider with a generous free plan.
Cloudflare R2
10 GBNo charge for downloads.
Backblaze B2
10 GBSimple object storage.
Any S3-compatible bucket
You decideAmazon S3, MinIO, Wasabi and others.
Encrypted before it reaches any provider
Your storage accounts hold your files, but they don’t get to read them.
- Every upload is encrypted with AES-256-GCM as it streams to your provider, unless you choose otherwise for that upload.
- Providers see scrambled data under a meaningless name; the real names stay with Storsum.
- Nothing is kept on the server. Files stream straight through and are never written to its disk.
Questions people ask
Is Storsum free?
Storsum costs nothing to use today. The space comes from the free plans of your own accounts, so you can start with just a Google account and add more as you go.
Where are my files stored?
In your own storage accounts: your Google Drive, Box, pCloud, Koofr or buckets. Storsum’s server streams each file to one of them and keeps only what it needs to find it again, such as its name, folder and which account holds it. File contents are never written to the server’s disk.
Can Google, Box or the others read my files?
Not the ones you encrypt, which is every upload unless you choose otherwise. The provider gets a file named something like 3f2a….enc holding scrambled data; the real name stays with Storsum. Files you upload without encryption are stored as they are, so you can also open them in the provider’s own app.
What happens when an account fills up?
New uploads go to an account that still has room. On the Storage page you can see how full each account is, move files from one account to another, or choose how uploads are spread: most room first, taking turns, or in an order you set.
Do I need a Google account?
No. You can sign up with an email and password and connect Box, pCloud, Koofr or any S3 bucket. Signing in with Google simply connects that Drive straight away.
