From a paste to your next device
Paste or drop
Paste a snippet or screenshot, or choose a file. Its preview appears while Zas prepares the send.
Open or share
Use the session QR to open it on another device. To send an item to someone else, create its share link.
Keep what matters
With an account, pin items to keep them. Let the rest expire automatically, without sorting through old uploads.
Zas vs Pastebin: choose for the task
Pastebin is a useful text-paste service. Zas suits temporary exchanges that also involve images, files, or another device.
| What you need | Zas | Pastebin |
|---|---|---|
| Text and code | Paste into a session; code snippets keep code formatting. | Text pastes with syntax-highlighting options. |
| Screenshots and files | Paste images or drop original files alongside text in the session. | Its documented paste API creates text pastes. |
| Another device | Open the session with its QR or session link. | Open a paste using its URL. |
| AI agents and automation | Connect Claude Code, Codex, or another MCP client. Agents send files and notes and read the channels you allow. Requires an account. | A developer API lets integrations create and retrieve text pastes. Requires API credentials. |
| Automatic cleanup | Items expire after 2 days without an account, or 5 days by default with one. Less to organize and delete later. | Choose an expiration for each paste, or no expiration. |
| Keep what matters | Pin items with an account to stop them expiring. They stay until you unpin or delete them. Pin limits depend on your plan. | Choose no expiration to keep a text paste. |

Moving between devices
Start on your computer and open the session on your phone without installing an app.
Sending something once
Pass along working material that does not need to become a permanent document.
Pin the items you want to keep; let the rest go. For version history or publishing an article, use a tool designed for that job.
Clear limits. Clear privacy.
Zas encrypts content on your device before upload. The service keeps account, channel, delivery, and expiry metadata needed to sync and remove items.
Your session link grants access to the session. Use an item’s share link when you only want to share that item.
This page measures actions and the steps to your first save using a temporary visit ID. Pasted content, filenames, and session links are excluded.
Read the privacy policyBefore your first paste
Do I need an account?
No. Pasting or choosing a file starts an anonymous session. You can return to it in the same browser or open its session link on another device.
Can I keep an item from expiring?
Yes. With an account, pin an item to keep it until you unpin or delete it, within your plan’s pin limit. Otherwise, items expire after two days anonymously or five days by default with an account. Automatic expiry means you do not have another storage space to organize and prune.
Can I paste images and upload files?
Yes. Paste a screenshot, drop a file, or use the file picker. The anonymous session has 30 MB of storage in total. Zas preserves original file bytes.
When is my content saved?
The preview acknowledges your content immediately. The item is saved after the send finishes; a preview alone does not mean it has been delivered.
Should I replace all my Pastebin links?
Start with your next exchange of code, screenshots, or files. With an account, pin anything you want to keep. Leave existing links in place if others still rely on them.
