How to Use Claude Desktop in 2026: Download, Install, Sign In & Get Started
Using Claude in the browser always feels like something's missing: open the browser → find the bookmark → click through → and now you're mixed in with dozens of other tabs.
The Claude Desktop app exists to fix exactly that — an official client, a dedicated window, built for one thing: using Claude.
Drag images and PDFs straight into the window. Conversations and Projects sync automatically with the web version. This guide walks you from download to first conversation, covering both Windows and macOS.
TL;DR: Allow about 10 minutes in three steps — ① download the installer from the official website → ② double-click to open once it's installed → ③ sign in with your Claude account and start chatting. On macOS drag it into Applications; on Windows just click Next a few times. That's really all there is.

Why Install Claude Desktop?
Think it through before you install.
The web version's real problem isn't capability — it's mindset: it sits in the same browser as all your work tabs. You write halfway through a message, switch over to reply, and come back with your train of thought gone.
The desktop app changes how you use Claude:
- A dedicated window: Claude stays front and center. Focused chat, no tab noise.
- Local drag-and-drop: Drop images, PDFs, and documents straight into the window — no upload step to sit through.
- Sync with the web: Start a conversation in the browser, continue it on the desktop app. History and Projects are all there.
- Calmer, more stable: No re-login every time — open it and it's ready.
In a word: if the web version is something you use "now and then," the desktop app becomes something you use "every day."
Preparation: Account and System Requirements
Two quick checks before you start.
① You need a Claude account
The desktop app signs in with your existing Claude (Anthropic) account — the one on claude.ai. Don't have one? Register for free on the official site.
- No account yet? Read How to Register a Claude Account
- Want to unlock the more powerful models (Pro / Max subscription)? See Subscribing to Claude Pro
② Confirm your system meets the requirements
| System | Requirement |
|---|---|
| macOS | A recent version of macOS — Intel or Apple silicon |
| Windows | Windows 10 / 11 (64-bit) |
The exact minimum system version is as marked on the official download page. If your system is too old to install, upgrade it or keep using the web version.
Installing on macOS
Step 1: Download the installer
Open claude.ai/download, pick the macOS version, and download the .dmg file. When the download finishes you'll find it in your Downloads folder.
Can't reach the official download page? See the FAQ below: "How do I get the Claude Desktop installer from outside supported regions?"
Step 2: Install
Double-click the .dmg to mount the disk image, then drag the Claude app icon into the Applications folder.
Step 3: Open it for the first time
Launch Claude from Launchpad or the Applications folder. If macOS says the app "cannot be opened" on first launch because it's unsigned, allow it to run under System Settings → Privacy & Security.
Installing on Windows
Step 1: Download the installer
Open claude.ai/download, choose the Windows version, and download the .exe installer file.
Step 2: Run the installer
Double-click the downloaded .exe and click through the prompts ("Next") to finish the installation. It installs into your local user directory by default — no extra configuration needed.
Step 3: Open it for the first time
After installation, find Claude in the Start menu and open it. If Windows shows a security prompt like "unknown publisher," confirm the download really came from the official website and choose "Run anyway."
Signing In and Getting Started
Once installed, open the desktop app and you'll see the sign-in screen.
How to sign in: Just like the web version — enter your account email and password. Email-registered accounts are supported, and some accounts offer quicker sign-in options; go with whatever the current sign-in screen shows.
After a successful sign-in you get a clean chat window. From here you can:
- Chat right away: Type a question in the input box and press Enter.
- Drag in files: Drag documents, images, or PDFs into the window to talk about them.
- Check the left sidebar: Your conversation history and Projects, synced with the web version.
If it keeps spinning after sign-in or shows a region-restricted message, follow the official guidance to confirm your network can reach Claude services normally.
Core Features of the Desktop App
Once you're in, these are the capabilities worth trying first:
- Projects: Organize conversations and background materials by project. Projects you create on the web show up here directly.
- Multimodal input: Drag in images, PDFs, spreadsheets, and code files for Claude to read directly.
- Long conversations that don't drop: The desktop app stays open for hours without losing context — great for writing long documents, editing code, and building plans.
- Conversation history: Every chat is saved automatically. Jump back into any conversation at any time.
Tools like CC Switch / Claude Code are different entry points with different purposes. For "programming from the terminal," see the Claude Code Guide.
Frequently Asked Questions (FAQ)
Q: Does Claude Desktop cost money?
No. The client is free — sign in with any Claude account and use it. A Pro / Max subscription unlocks more powerful models and higher limits, but the client itself isn't billed separately.
Q: Do chat records sync between the desktop app and the web version?
Yes. Both use the same account, and conversations and Projects sync in real time — a conversation started on the web can be continued on the desktop app.
Q: Does Claude Desktop support Windows?
Yes — there are both Windows and macOS versions, both on the official website.
Q: How do I get the Claude Desktop installer from outside supported regions?
If the official website is slow or unreachable, try: switch to a stable network environment and download from the official site, or use a tool that can reach the official site reliably to fetch the installer. The installer itself is just a program of a few hundred MB — once downloaded, both installation and sign-in happen locally on your machine, with no extra dependencies.
Q: After installing, opening the app says "cannot verify the developer." What now?
macOS: go to System Settings → Privacy & Security, allow apps from "App Store and identified developers," then reopen the app. Windows: after confirming the installer was downloaded from the official site, choose to allow it in the security prompt.
Closing Thoughts
Claude Desktop isn't a reskin — it's a different way of working with Claude. Once it's installed, the first thing we'd suggest isn't asking it a question. It's:
Throw in an old project you've been meaning to tidy up for ages and see what happens.
You'll find that the genuinely comfortable starting point for "using Claude" is the desktop app.
