Everything CopyShareNow does — in one free tab
CopyShareNow bundles the three things every developer, student and office worker reaches for a dozen times a day: a universal clipboard to move text between devices, a free QR code generator with every format that actually gets used, and a toolbox of online developer utilities. No signup, no app store, no paywall.
📋 Clipboard sync between devices
Paste text on your phone, open the site on your laptop, type the 6-character code — your text is on the clipboard. Works across iOS, Android, Windows, macOS, Linux and ChromeOS.
📷 QR code generator
Create QR codes for URLs, WiFi logins, vCards, SMS, email, calendar events, geo-locations, PayPal, Venmo, YouTube, Spotify and more. Download as PNG.
🧰 Online developer tools
JSON & CSV formatter, Base64, MD5/SHA hash generator, diff checker, XML ↔ JSON, URL encoder, JWT decoder, regex tester and Markdown — all client-side.
🔒 Privacy-first by design
Clips auto-expire after 30 minutes. Firebase App Check and reCAPTCHA v3 block abuse. No account, no email, no tracking cookies beyond anonymous analytics.
How to send clipboard text between two devices
- On device A, open copysharenow.com and paste your text into the big box.
- Click Generate Code. You get a short code like
A3K9PQand a QR code you can scan. - On device B, open the same URL, type the code (or scan the QR), and your text is copied to the clipboard automatically.
The whole flow typically takes under 10 seconds and works in any modern browser — Chrome, Firefox, Safari, Edge and Brave — without installing an extension or a mobile app.
Common use cases
- Send a long URL from desktop to phone without typing it.
- Move a snippet of code between a work laptop and a personal machine.
- Share a WiFi password with a guest via WiFi QR code.
- Transfer a 2FA backup code between devices during account setup.
- Beautify a minified JSON blob pulled from a production log.
- Decode a JWT to debug an auth header.
- Test a regex pattern before shipping it in code.
- Generate a vCard QR for a printed business card.
Frequently asked questions
Is CopyShareNow really free?
Yes — 100% free with no ads and no premium tier. It runs on Firebase's free (Spark) tier. If it saves you time, there's an optional Buy Me a Coffee tip jar, but nothing is gated behind it.
Do I need to install anything?
No. CopyShareNow is a website. It works on any modern browser (Chrome, Firefox, Safari, Edge, Brave) on Windows, macOS, Linux, Android, iOS and ChromeOS. You can also add it to your home screen as a PWA.
How private is it?
Share codes are random, clips auto-expire after 30 minutes, Firebase App Check + reCAPTCHA v3 block bots and abuse, and there is no account or email collected. Only anonymous Google Analytics is used to count pageviews.
What is the clipboard size limit?
Up to 50,000 characters per clip — enough for long log dumps, multi-file code snippets and formatted text.
Can I share files?
CopyShareNow is built for text (links, code, notes, credentials, configuration). For binary files, use a dedicated file-sharing service.
What QR formats are supported?
URL, plain text, WiFi, vCard contact, SMS, phone call, email, geo-location, calendar event, PayPal, Venmo, YouTube, Spotify, crypto addresses and more — 18+ formats in total.
Which developer tools are included?
JSON / CSV formatter & validator, Base64 encoder/decoder, hash generator (MD5, SHA-1, SHA-256, SHA-512), side-by-side diff checker, XML ↔ JSON converter, URL encoder, JWT decoder, regex tester with live match highlighting, and a Markdown editor with live preview.
Is there a CopyShareNow mobile app?
Not as a native app — the site is a PWA, so you can "Add to Home Screen" on iOS or Android and it behaves like an app (fullscreen, offline-ready favicon, instant launch).
Alternatives to CopyShareNow
Looking at other clipboard-sync tools? CopyShareNow is designed to be the zero-friction option: no login, no installer, no subscription. Tools like Pushbullet, SnapDrop, ClipboardFusion and the built-in Apple Universal Clipboard are great if you're locked into one ecosystem or willing to install software, but they all require either an app, an account, or same-vendor devices. CopyShareNow works from any browser to any browser.
