HOW TO USE RUN DROP
OFFLINE & AIR-GAPPED

Animated Optical QR Streaming

Transfer files completely offline through high-speed animated QR code streams displayed on your screen and captured by any camera without internet or Bluetooth.

1 Select files or write text/code on the Home page, then choose "Animated QR" in share options.
2 A high-density visual stream loops across your screen at optimized frames per second.
3 The receiver opens the built-in scanner on any phone, tablet, or laptop camera.
4 The file is assembled and saved directly in the receiver's browser with zero network footprint.
SAME WI-FI NETWORK

Instant Same-Wi-Fi Device Sharing

Instantly discover and share transfers with nearby phones, tablets, and computers connected to your same local Wi-Fi without uploading to outside servers or pairing cables.

1 Open RunDrop on both devices while connected to the same Wi-Fi network.
2 Upload your file and toggle "Publish to Local Wi-Fi" (add an optional 4-digit PIN for extra privacy).
3 The receiving device navigates to the "Receive" tab and taps "Local Wi-Fi".
4 Nearby transfers appear on the radar board instantly for 1-tap download.
LIVE RUNNER & PREVIEW

Live Real-Time Code Preview & Sandboxes

Write or paste code in 13+ languages with real-time live preview rendering as you type—no need to repeatedly hit the run button to see your UI updates, styling, or output.

1 Switch to the "Code Snippet" tab on the Home page and select your language.
2 Live interactive preview renders your HTML, CSS, JavaScript, SVG, or Markdown instantly as you type.
3 Safe in-browser sandbox isolates execution to protect your device and privacy.
4 Share with an 8-character code so collaborators can inspect, fork, or run your code in real-time.
CAMERA SCANNER

Universal Camera QR Scanner

Scan standard RunDrop QR codes or animated optical streams directly inside your web browser using any front or back camera—zero third-party apps or browser extensions needed.

1 Go to the "Receive" page on any device and select "Scan QR Code".
2 Allow camera access when prompted by your browser (rear or front camera supported).
3 Align the camera with the QR code or stream displayed on the sender's screen.
4 Instant detection automatically redirects to your transfer or reconstructs stream data.
VANITY & SHORT CODES

Private Link Shortener & Auto-Purge

Turn lengthy URLs, file downloads, or code snippets into clean, memorable 8-character codes or custom vanity names with automated expiration and click tracking.

1 Choose "Share URL / Link" or set a Custom Code when sharing any file or note.
2 Pick a custom vanity slug (e.g., "design-brief" or "demo-v1") or generate an 8-character code.
3 Set automatic expiration time or enable self-destruct after the first click.
4 Receivers open your clean short link directly or type the code in the Receive portal.
BATCH TRANSFERS

1-Click Batch ZIP & Auto-Resume

1 Drag and drop multiple files or entire folders into the upload dropzone.
2 Upload chunks stream smoothly with automatic pause-and-resume if your connection hiccups.

PRIVACY & SECURITY GUARANTEES

Frequently Asked Questions

Click on any question below to view the answer.
HELP & KNOWLEDGE BASE
Do I need to create an account to send or receive files?
No account is required! You can send and receive files, code, notes, and links immediately as a guest. Simply upload or write what you want to share, get an 8-character code or QR, and the receiver can open it right away on any computer, phone, or tablet.
What kinds of files can I share?
You can share any file type, including photos, videos, PDF documents, spreadsheets, presentations, music, apps, code files, and compressed folders. There are no restrictions on file extensions.
Can I upload multiple files at the same time?
Yes! You can select or drag and drop multiple files at once. When you share multiple files, RunDrop automatically packs them into a single neat folder so the receiver can download everything together in one click.
What happens if my internet connection drops during an upload?
Your upload will not be lost! RunDrop automatically saves your progress. As soon as your internet reconnects, the upload picks up right where it left off, so you do not have to restart from the beginning.
How does the in-browser code runner and preview drawer work?
RunDrop includes a built-in code editor for 13+ popular languages like JavaScript, Python, and HTML. You can format your code with one click, run JavaScript and Python directly inside your browser to see output instantly, or open an interactive live preview drawer to test websites and HTML designs without installing any software or apps.
Can the person receiving my code run it or test it on their device?
Yes! Anyone who opens your 8-character code or scans your QR code can view clean, easy-to-read code with line numbers. If it is a website design or script, they can open the live preview drawer and test it interactively right in their web browser.
How does Nearby Device Sharing work on the same Wi-Fi?
If you and another person or device are connected to the same Wi-Fi network, you can open the Nearby Board to find each other automatically. You can send files, notes, or links directly between devices without emailing them, and you can add a simple PIN number so only the right person can connect.
Can I send files from my computer to my phone with a QR code?
Yes! Whenever you share something, a QR code appears on your screen. Just point your phone camera at the screen to open the transfer on your phone instantly, without typing long web addresses.
How do Self-Destruct (Burn-on-Read) and Passwords protect my shares?
When you turn on Self-Destruct, your shared files or notes are permanently deleted the very first time the recipient opens or downloads them. You can also add a private password, meaning only people who know your password can unlock and view what you sent.
Where are my files kept and when are they deleted?
Files and notes are stored securely in temporary cloud storage. They are kept only for the time you choose (3 hours on the Free plan, or up to 7 full days on paid plans). Once the timer ends, our system permanently erases the files with zero trace left behind.
Can I set a maximum download limit for my files?
Yes! You can choose how many times your file can be downloaded (for example, 1, 5, or 10 times). As soon as that number of downloads is reached, access closes immediately, even if the expiration timer has not finished.
Can I delete a file I shared before the timer expires?
Yes! If you create a free account and share while signed in, all your active transfers appear in your personal Dashboard. You can view their status and permanently delete any transfer at any time with a single click.
Can I choose my own custom 8-character share code?
Yes! Members on our Premium Pro and Ultra Max plans can pick their own custom 8-character codes using letters and numbers (like MYFILES1 or TEAM2026). Our system checks right away to make sure the code is available. Free guest shares receive secure random 8-character codes automatically.
What are the storage limits for Free Starter, Premium Pro, and Ultra Max?
Free Starter ($0) allows up to 250MB and 5 files per batch with 3-hour expiration and full in-browser code previews. Premium Pro ($2.99/mo) gives you 1GB per transfer, up to 50 files per batch, custom shortcodes, 7-day storage, and your personal Dashboard. Ultra Max ($5.49/mo) gives you our highest limit of 5GB per transfer, up to 100 files, fastest upload speeds, and priority help.
How do I receive files using an 8-character code?
Go to the Receive page, type the 8-character code (or scan the sender's QR code with your phone camera), and tap Access Content. Your files, notes, or code will appear immediately on your screen for instant download or viewing.
Why does a transfer say it is invalid or expired?
A transfer becomes unavailable when its expiration timer has ended, or when it was set to Self-Destruct and has already been opened, or if the sender manually deleted it from their Dashboard. If this happens, please ask the sender to share a new code.
