Sending a file sounds simple until it is too large for email, contains sensitive client information, or needs to reach several people without creating version-control problems. The best file sharing apps solve different parts of that challenge. Some are built for quick one-off delivery, while others combine cloud storage, permissions, collaboration, and long-term access.
The right choice usually comes down to file size, recipient access, security controls, device support, and how long the file must remain available.
Best file-sharing apps for different needs
Google Drive: best for everyday collaboration
Google Drive is a strong default for documents, spreadsheets, presentations, photos, and shared project folders. Individual files can be as large as 5 TB, provided your account has enough storage. You can share with specific people or create a link and assign viewing, commenting, or editing permissions.
Its main advantage is collaboration. Teams can work from the same folder across browsers and mobile devices instead of emailing revised copies. Google encrypts Drive data in transit and at rest, but standard Drive storage is not end-to-end encrypted. For sensitive material, restrict access to named recipients instead of using a broadly accessible link.
Dropbox: best for polished client delivery
Dropbox combines cloud storage with straightforward sharing links and Dropbox Transfer for finished files that do not need ongoing collaboration. Dropbox supports individual uploads up to 2 TB, although extremely large uploads are more reliable through the desktop app than through a browser.
It works well for video exports, design packages, photography, and client handoffs because recipients can often download from a link without joining your workspace. Depending on the plan, Transfer can add passwords and custom expiration dates. Dropbox also supports web, Windows, macOS, iOS, and Android.
Microsoft OneDrive: best for Microsoft 365 users
OneDrive is a natural choice for people already working in Windows, Word, Excel, PowerPoint, and Microsoft 365. The maximum size for an individual file is 250 GB. Sharing can be configured for viewing or editing, while Microsoft 365 subscriptions can add options such as password-protected links and expiration dates.
For businesses already using Microsoft accounts, OneDrive can be simpler than separate file transfer software. Some work and school sharing scenarios also allow download blocking.
WeTransfer: best for quick one-off transfers
WeTransfer is designed for a simple workflow: upload files, create a transfer, and send the recipient a link. Free accounts currently allow up to 10 transfers or 3 GB of transferred data within a 30-day period, and free transfers stay active only for a limited time.
That makes it useful when you need to send files online without maintaining a permanent shared folder. It is well suited to finished videos, photo batches, and compressed project folders, but less suitable for long-term collaboration or files that must remain continuously available.
Proton Drive: best for privacy-focused sharing
Proton Drive stands out among secure file transfer apps because file contents, filenames, and folder names are protected with end-to-end encryption. Proton says individual file size is limited by the storage available in your account rather than by a separate per-file cap. Its free plan includes 5 GB of storage.
Public links can be protected with a password and expiration date, and sharing permissions can allow viewing or editing. Proton Drive supports web, Windows, macOS, Android, and iOS, making it a strong option for contracts, financial records, research files, and other sensitive material.
Sync.com: best for controlled secure links
Sync.com also focuses heavily on privacy and access controls. Its free plan includes 5 GB of storage, password-protected links, and end-to-end encrypted storage. Paid plans add features such as link expiry dates, download limits, view-only sharing, and more advanced collaboration controls.
The free tier has tighter sharing limits, including limits on active links and daily downloads per link, so regular external sharing may justify a paid plan. It is a useful choice when security matters and you want more control over what recipients can do after opening a link.
How to choose the right service
Start with the job. For live collaboration, Google Drive or OneDrive usually makes the most sense. For delivering a completed project, Dropbox Transfer or WeTransfer is more direct. If privacy is the priority, Proton Drive or Sync.com offers stronger end-to-end encrypted sharing options.
File size matters too. OneDrive supports files up to 250 GB, Dropbox supports uploads up to 2 TB, and Google Drive supports individual files up to 5 TB when storage allows. Proton Drive does not impose a separate individual file-size ceiling beyond your available storage. For large file sharing, use a desktop sync app where possible because it can handle interrupted uploads more reliably than a browser.
Consider a 70 GB video project going to a freelance editor. WeTransfer may be convenient if your plan covers the transfer size and short-term access is enough. Dropbox is better for repeated professional deliveries. OneDrive is convenient if both sides already use Microsoft 365. Proton Drive is a stronger fit if the footage is confidential and end-to-end encrypted sharing is the priority.

Security checks before sending files
A secure platform can still be undermined by a badly configured link. For sensitive transfers, share with named recipients where possible, use a password when available, set an expiration date for temporary access, and revoke the link after the project is finished. If the file is especially sensitive, send the password through a different communication channel.
Also check whether recipients can edit, download, or re-share the file. A view-only link may be best for a draft, while an editable folder makes more sense for collaboration. These permission choices are often more important than simply choosing the service with the largest storage limit.
FAQ
What is the best file-sharing app for large files?
Google Drive, Dropbox, OneDrive, and Proton Drive all support substantial uploads. The best option depends on your storage plan, required permissions, and whether the transfer is a one-time delivery or part of an ongoing collaboration.
Which file-sharing app is best for sensitive files?
Proton Drive and Sync.com are strong choices when end-to-end encryption is a priority. Whichever service you choose, use restricted sharing, passwords, expiration dates, and link revocation when those controls are available.
Can I share files without making the recipient create an account?
Yes. WeTransfer, Dropbox Transfer, Proton Drive public links, and many standard cloud-sharing links can let recipients download files without creating an account, depending on the sharing settings you select.
Are free file-sharing apps secure?
Many are secure for ordinary use, but free plans may limit storage, transfer volume, active links, or advanced access controls. Check the service’s encryption model and link permissions rather than assuming all free plans provide the same protection.
Conclusion
There is no single best option for every transfer. Google Drive and OneDrive are strongest for collaboration inside their ecosystems, Dropbox is excellent for professional delivery, WeTransfer keeps one-off transfers simple, and Proton Drive or Sync.com makes sense when privacy and tighter link controls matter most. Match the service to the file size, recipient, security level, and length of access you actually need.
