01 / Overview

What is a clipboard inspector?

A clipboard inspector is a tool that shows every data format currently on your clipboard - not just the plain text you see when you paste, but the HTML, rich text, images, URLs and custom formats copied alongside it. Each format is listed with its MIME type, byte size and a live preview.

How to use

  1. 01
    Copy something

    Copy text, a link, an image, or a chunk of a web page from any app.

  2. 02
    Paste into the box

    Click the paste area and press Ctrl+V (Cmd+V on Mac), or use the Read clipboard button.

  3. 03
    Inspect the formats

    Read each format's MIME type, size, character and line counts, and preview - render HTML or view the source.

Who it's for

  • Developers debugging copy and paste, drag and drop, or a rich-text editor - confirm which MIME types and custom web formats an app actually writes.
  • Writers and editors who want to know why pasted text arrives with unwanted styling, and whether a plain-text version is available.
  • Curious users who simply want to see what is really on their clipboard right now, including hidden HTML and image data.

When you copy something, most apps put several versions of it on the clipboard at once - a web page copy usually carries both styled text/html and a fallback text/plain, and the app you paste into picks whichever it prefers. This inspector reveals all of them so you can see exactly what will paste and why formatting sometimes carries over when you did not expect it.

Everything runs entirely in your browser. Your clipboard is read locally with the paste event or the browser's Clipboard API and is never uploaded, logged, or sent anywhere.

FAQ

Why does my clipboard have both HTML and plain text?

Apps write several formats for one copy so the destination can choose. A browser copy stores text/html to preserve styling and text/plain as a fallback for apps that only accept plain text. The inspector lists every version present.

Can it read images and files on the clipboard?

Yes. Pasted or copied images (PNG, JPEG, GIF, WebP and more) show a thumbnail preview with their pixel dimensions and byte size. Binary data with no text representation is listed with its type and size.

Is my clipboard data private?

Completely. The tool reads your clipboard locally in the browser and processes everything on your device. Nothing is uploaded, stored, or transmitted to any server.

Why is the Read clipboard button blocked?

The Clipboard API needs permission and a secure context, and some browsers restrict it. If reading is blocked, click the paste box and press Ctrl+V (Cmd+V on Mac) instead - the paste path always works.

Does it work on mobile?

Yes. Tap the paste box to focus it, then use your keyboard's paste option. Mobile browsers may expose fewer formats than desktop, since some rich and custom types are desktop-only.
