You cannot block someone directly through Snapchat Web
Snapchat Web does not have a block feature. The web version is designed for viewing stories and messages only — it does not include the privacy controls you need to block another user. To block someone, you must use the Snapchat mobile app on iPhone or Android.
If you are on a computer and need to block someone right now, you have two options: read the Snapchat app to your phone, or use your browser's mobile view to access the full app features. The mobile app is the fastest route because blocking takes less than a minute once you open it.
Key Takeaways
- Snapchat Web does not include blocking tools — you must use the mobile app on a phone or tablet to block another user.
- Open Snapchat on your phone, find the person in your contacts or recent messages, swipe left on their name, and tap "Block".
- When you block someone, they cannot send you messages, see your stories, or add you as a friend, but they can still see old messages you sent before the block.
- If you want to block someone from your computer, use your phone's browser to access Snapchat in mobile view, which gives you access to the block feature.
How to block someone using the Snapchat mobile app
Open Snapchat on your phone and go to the Chat tab at the bottom of the screen. Find the person you want to block — you can scroll through your recent conversations or search for their username at the top. Once you find them, press and hold their name until a menu appears.
Tap "Block" from the menu that pops up. Snapchat will ask you to confirm — tap "Block" again. The person is now blocked. They will not see that you blocked them, but they will notice they can no longer message you or see your stories.
If you want to block someone who is not in your chats, go to your Friends list, find their name, swipe left on it, and tap "Block". The process is the same either way.
What happens when you block someone on Snapchat
When you block someone, they when ready lose the ability to send you new messages, call you, or see your stories. They cannot add you as a friend or view your profile. However, messages you sent them before you blocked them will still be visible on their end — blocking only stops future contact.
The blocked person will not receive a notification that you blocked them. They will straightforward see that they cannot message you anymore. If they try to add you, your profile will not appear in their search results.
You can unblock someone at any time by going to Settings, tapping "Blocked", finding their name, and swiping left to unblock them. Unblocking does not automatically re-add them as a friend — they will need to send a new friend request.
Blocking someone from Snapchat Web using mobile view
If you are on a computer and do not have access to your phone, you can use your browser's mobile view to access Snapchat's full features. Open Snapchat Web in your browser, then press F12 (or right-click and select "Inspect") to open the developer tools. Click the mobile device icon in the top left of the developer tools to switch to mobile view.
Refresh the page. Snapchat will now load in mobile format, and you will see the Chat tab and blocking options. Follow the same steps as the mobile app: find the person, press and hold their name, and tap "Block". This method works on any computer with a modern web browser.
Mobile view can be finicky depending on your browser, so if it does not work smoothly, downloading the Snapchat app to your phone is the more reliable option.
Blocking versus other privacy options on Snapchat
Snapchat offers other ways to control who can contact you without blocking. You can set your privacy settings so that only friends can message you, or you can mute someone's stories without blocking them. Muting hides their stories from your feed but does not prevent them from messaging you.
If someone is harassing you, blocking is the right choice. If you straightforward do not want to see their stories but are okay with them messaging you, muting is less severe. You can also report someone to Snapchat if they are sending threatening or inappropriate messages — go to the message, swipe left, and tap "Report".
