FAQ
Frequently asked questions
Everything you need to know about using WorTrans for secure file transfers.
What is the maximum file size I can send with WorTrans?
WorTrans supports file transfers up to 20GB per upload with no compression required. Files are split into 32MB chunks and uploaded through 8 parallel streams for maximum speed. There is no daily transfer limit.
Is WorTrans completely free to use?
Yes, WorTrans is 100% free with no hidden costs, no registration required, and no email verification. Simply drag and drop your files to start transferring. All features including 20GB uploads, parallel acceleration, and SHA-256 verification are included at no cost.
How long do uploaded files stay available?
Files are automatically and permanently deleted after 24 hours or after reaching the configured download limit (1-50 downloads), whichever comes first. No data is retained after deletion.
How does WorTrans ensure file security?
Every file is verified using SHA-256 cryptographic hashing, the same algorithm used by financial institutions. Combined with configurable download limits, automatic 24-hour expiration, and content-addressable storage, your files remain under your control at all times.
Can I share the download link before the upload finishes?
Yes! WorTrans computes the file hash before uploading begins, so the download link is generated instantly. Share it immediately with the recipient. They will see a real-time progress page showing upload status, and their download will start automatically when the upload completes.
Can I send multiple files at once?
Yes. When you select or drop multiple files, WorTrans automatically bundles them into a single ZIP archive for convenient transfer. Individual files are uploaded directly without any bundling.
What makes WorTrans faster than WeTransfer?
WorTrans uses 8x parallel upload streams and 32MB optimized chunks, compared to single-stream uploads on most services. Client-side SHA-256 hashing also enables instant duplicate detection - if a file already exists on the server, the transfer completes in under 2 seconds with zero bytes transferred.
Does WorTrans work on mobile devices?
Yes. WorTrans works on any modern browser across Windows, macOS, Linux, iOS, and Android. No app installation or plugins required. The interface is fully responsive and optimized for all screen sizes.
What happens if the same file is uploaded twice?
WorTrans uses SHA-256 content-addressable deduplication. If the same file content already exists on the server, the upload completes instantly with zero bytes transferred, saving both time and bandwidth. The new download link is generated immediately with your chosen download limit.
Does WorTrans require creating an account?
No. WorTrans requires zero registration. Simply visit the site, drop your files, and share the generated download link. No email, no account, no personal information collected. Complete anonymity for both sender and recipient.

Enterprise-Grade Security Without the Enterprise Price
Every file uploaded to WorTrans is verified using SHA-256 cryptographic hashing, the same algorithm used by financial institutions and government agencies to ensure data integrity. Combined with configurable download limits and automatic 24-hour expiration, your files remain under your control at all times. Files are stored using content-addressable naming, making download URLs cryptographically secure and impossible to guess.
Built for Speed: How Parallel Upload Technology Works
WorTrans employs several advanced techniques to maximize transfer speed. Files are split into 32MB chunks and uploaded through 8 parallel streams, fully utilizing your available bandwidth. Client-side hash computation enables instant duplicate detection - if a file was previously uploaded by anyone, the transfer completes in under 2 seconds regardless of file size, with zero bytes transferred over the network. Each chunk includes automatic retry logic (up to 3 attempts) to ensure reliable delivery even on unstable connections.
Share Links Before Upload Completes
WorTrans computes the SHA-256 hash of your file before the upload begins, generating the download link instantly. You can share this link with recipients right away, even while the file is still uploading. Recipients who open the link will see a real-time progress page showing upload status, file name, and estimated completion time. Once the upload finishes, their download starts automatically - no page refresh needed.
Perfect for Every Use Case
Whether you're a videographer sending raw footage to clients, a developer sharing application builds with testers, a designer delivering high-resolution assets, or simply need to send a large presentation to a colleague, WorTrans handles it all. The platform supports any file type, works across all devices and browsers, and requires no software installation.
Cross-Platform Compatibility
WorTrans works on any modern browser across Windows, macOS, Linux, iOS, and Android. No software installation, no plugins, no configuration. Drag and drop your files from any device and share the download link with anyone, anywhere in the world. The responsive interface adapts seamlessly to desktop, tablet, and mobile screens.
How WorTrans Compares to WeTransfer, Google Drive, and Dropbox
WorTrans stands apart from traditional file transfer and cloud storage services. WeTransfer's free tier limits files to 2GB and requires email. Google Drive requires a Google account and counts against your storage quota. Dropbox Transfer limits free users to 100MB. WorTrans offers 20GB transfers with no registration, parallel upload acceleration, cryptographic verification, and configurable download limits - all completely free. For users who need fast, secure, anonymous file transfers, WorTrans is the clear choice.
