Unlimited File Sharing — Any Size
At file.kiwi, file size is just a number. You can upload any file immediately without restrictions.
- No Sign-up Required: Use it immediately without registration.
- No ads: Nothing to watch or click through.
Fail-safe File Sharing
file.kiwi provides recovery features for when things go wrong. Even if the browser window closes mid-transfer, you can pick up right where you left off.
- Resume download: Allows you to download from the point where it was interrupted.
- Resume upload: You can continue uploading from where it stopped.
- No Installation Required: Nothing extra to install or set up.
Flexible File Sharing with Web Folders
A Web Folder is a dedicated internet storage space for sharing.
- Each Web Folder has its own unique link (URL) that makes it easy to share.
- Works with Outlook and corporate email systems that limit attachment sizes, as well as Gmail, social media, and blogs.
- For light use, jump right in — no signup needed.
- Sign up for precise control over read/write permissions.
Encrypted File Sharing
Your original file never leaves your device unencrypted.
- No one can see what's inside — files are encrypted before upload, and neither the original nor the decryption key is ever stored.
- No one can search, view, or censor your files.
Powerful File Sharing Features
Unlimited file uploads that start instantly, with zero interruptions.
Nothing stands in the way of uploading your files — just select them, and the upload begins instantly. We don't limit file size: 10 GB or 500 GB, it makes no difference. You can upload all types of files, including videos, documents, and images. No ads to watch, no signup walls, no waiting queues, no throttled uploads based on file size. Try sharing even your largest files in one go, without splitting them.
Delivered securely without storing the original — then destroyed completely.
We use end-to-end 128-bit AES-GCM encryption without storing the original file or decryption key on the server. File names are also encrypted, so files cannot be read without the shared link. Files are permanently deleted when their configured lifetime ends. Web Folder+ owners can use folder capacity to extend file lifetime in 7-day increments.
Convenient Shared Folders and Batch Transfers
Because you share an entire folder (a Web Folder), you can deliver multiple files at once. Just drag and drop — like moving files into any folder — and the upload starts immediately. Even large batches of files can be uploaded in one go.
Real-time Sharing
You can share as soon as the upload starts, meaning you don't have to wait for the upload to reach 100% to share the file. This can significantly reduce the sharing time, especially for large files. Whether the file size is 50GB or 100GB, sharing starts in about 10 seconds. Furthermore, if the file is an MP4, it can be played immediately, resulting in zero waiting time for both the sender and the receiver.
Simple Link Sharing
Web Folders created on file.kiwi have a unique link address (URL). Just send the link and sharing begins instantly. It can also be generated as a QR code, making it readable from other devices and easily shared with a single click. Alternatively, you can copy the link and paste it into an email or a chat message.
Convenient two-way sharing for collaboration
Beyond simple transfers, a Web Folder can also act as a shared file box where multiple people can upload and download files. Alternatively, you can allow only uploads, making downloads available exclusively to the Web Folder creator. This way, it can be used for collecting files, like a mailbox or a drop-off point. It's especially convenient for receiving files from people who aren't familiar with file transfers — all they need is the link.
Resume download / Resume upload support
When uploading or downloading files, network errors can occur. Starting over each time is a waste of time, and for large files, it may not be feasible at all. file.kiwi internally splits file transfers and allows you to resume from where they left off, rather than starting from the beginning.
Apps and tools for every workflow
Beyond the browser, file.kiwi ships as a Windows app (right-click from File Explorer), a Chrome extension (right-click inside any text input), a CLI (`npx @file-kiwi/node`), and an MCP server that lets AI tools like Claude or Cursor upload and hand back a download link on command. Pick the integration that fits your workflow.
Try It OutFile Sharing for Various Uses
When sending large files as email attachments
file.kiwi comes in handy when sending large files via email. Just put the file in the Web Folder and insert the link into the body of the email. Since the original file is not stored on an external service, it's safe to use even at security-conscious companies.
Share original photos/videos with friends
Photos and videos from trips and parties with friends are meant to be shared. While there are many social media platforms, sharing original files is not always easy, and free options for sharing large files can be scarce. file.kiwi can serve as a shared folder where participants can upload files collaboratively without any sign-up requirements or storage limits. You can preview files on the web and select the ones you want to download all at once.
When you need to receive large files from someone who isn't tech-savvy
Sending large files isn't easy for everyone. It can be difficult for those not familiar with things like splitting and compressing files or using cloud services, and for the recipient, walking someone through it over the phone is just as painful. file.kiwi solves this by simply sharing a Web Folder link. File uploads proceed quickly and intuitively without file size restrictions or other conditions. Try It Out
When you need to collect files from many people
Receiving files by email from many senders burns hours. A Submission Web Folder acts as a drop-off point — contributors simply click a link and pick files, no account, no instructions. The collector downloads everything accumulated in one batch. From the submission request to the download, everything is handled via a single shared link without exposing a single email address.
Play videos from your phone on another device
When you want to watch MP4 videos from your device on a smart TV or any other big screen, you can play them directly — no login, no pairing, no setup. All you need is a browser on the device you want to play them on. Play phone videos fullscreen in a Tesla
Receive files without exposing your personal email
Receiving files through forums or social media usually means exposing your personal email address. With a Submission Web Folder address created on file.kiwi, you can receive files safely instead. It's convenient for everyone — senders share their files with a single click.
Frequently Asked Questions
What is file sharing?
File sharing is the act of distributing digital files — documents, videos, photos, archives — between people or devices over the internet. Modern cloud-based file sharing replaces USB drives, email attachments, and FTP with a one-link flow: you upload once, and anyone with the link can download directly without installing software.
How does file sharing work on file.kiwi?
When you pick a file, your browser encrypts it with 128-bit AES-GCM before anything is sent. The encrypted blob is stored on our server; the decryption key lives only inside the share link. When the recipient opens the link, their browser fetches the blob and decrypts it locally. Your original file never sits unencrypted on our disk.
What is the main benefit of cloud-based file sharing?
The main benefit is decoupling sender and receiver in both time and place. A recipient in a different time zone, on a different OS, behind a different network can still download on their own schedule — without installing software, pairing devices, or hitting the size limits of email or chat apps.
Does the recipient also need to install it?
file.kiwi is essentially a webpage. With just a web browser, you can use all the features. Neither the sender nor the recipient needs to install anything.
How can this service be free — without even ads?
file.kiwi is free by default, but there are premium benefits.
Is there really no file size limit for file sharing?
file.kiwi doesn't impose any file size limits of its own. In practice, the maximum size depends on your device and browser. Desktops handle very large files more reliably than phones — see Help & Support for device-specific limits.
Is file sharing on file.kiwi secure?
Yes. Files are end-to-end encrypted in your browser with 128-bit AES-GCM before upload. The decryption key never leaves the share link, so nobody — including us — can read the content without it. Encrypted files are auto-deleted from the server after 90 hours by default.
Is free file sharing really safe?
Not always. Many free services are free because they monetize metadata, sell access, or skip encryption. file.kiwi is the opposite: files are encrypted client-side before upload, the decryption key never reaches our server, and the encrypted blob is deleted after 90 hours by default.
Can I download files directly to an external hard drive?
Yes — on a PC, you can save downloads straight to an external drive, so nothing takes up space on your C: drive. Please check out the Large File Download Guide.
Can it be used on mobile devices (iOS or Android)?
Yes, though very large files may be constrained by your device's performance. See related help
