How OneDrive files are processed in Filecraft

Files from OneDrive are downloaded directly to your browser, processed locally, and saved back — without passing through Filecraft's servers.

File bytes travel between your browser and Microsoft — never through Filecraft.

How it works

Follow your file from OneDrive to your browser and back. Filecraft never holds the bytes.

1
You select a file from OneDrive
The cloud picker shows your folders. Filecraft's server requests a temporary download URL from Microsoft Graph — it never downloads the file itself.
Microsoft → Your browser
2
Your browser downloads directly from Microsoft
The file is fetched from Microsoft's CDN using the temporary URL. Filecraft's server is not in the path.
Your browser
3
Processing happens locally
Web Workers for PDFs, Canvas API for images. No file content is sent anywhere.
Still your browser
4
You save the result back to OneDrive
Your browser uploads directly to Microsoft using a pre-authenticated session. Filecraft never touches the file bytes.
Your browser → Microsoft

The key point: File bytes always travel between your browser and Microsoft. Filecraft's servers handle authentication metadata only.

Common questions

Does Filecraft store my OneDrive credentials?

Filecraft uses Microsoft OAuth to authenticate you. Your password is never shared with Filecraft. The authentication token is used server-side to generate temporary download and upload URLs, then discarded.

Can Filecraft access all my OneDrive files?

Filecraft requests the minimum permissions needed to list and download files you explicitly select. It cannot access files you do not choose through the picker.

What happens if I close the tab mid-processing?

The file in browser memory is discarded. Nothing has been uploaded to Filecraft's servers, so there is nothing to clean up. You can re-open the tool and start again.

Is the save-back feature uploaded through Filecraft servers?

No. Save-back uses a pre-authenticated upload session. Your browser uploads the result directly to Microsoft's servers using the upload URL. Filecraft's server generates the upload session but never handles the file bytes.
