Best Free Cloud Storage
Mega gives the most free storage at 20 GB, followed by Google Drive at 15 GB. The right pick depends on whether you want the largest free tier, the tightest privacy (Proton Drive, Mega), or the deepest integration with an office suite you already use (Google Drive, OneDrive).

FAQ
Which free cloud storage has no file size limit?
Most free tiers cap individual file uploads well below the total storage quota (commonly 5–10 GB per file). For a single very large file, a dedicated transfer tool from the alternatives list is usually faster than uploading to cloud storage.
