Clipboard Inspector: See What You Pasted (MIME Types, HTML, Images)
Focus the paste area below and press Ctrl+V (⌘+V on Mac) to list every format the browser receives in the paste event. You get each MIME type such as text/plain and text/html, its contents and size, image previews with dimensions, and the names and types of any files. HTML is only shown as source text; it is never rendered or executed. Handy for building and debugging paste handling in web apps. Everything runs in your browser and nothing is sent to a server. To convert special characters in HTML, use the HTML Escape tool.

How to use
- Copy what you want to inspect in another app or page (images, tables and files work too).
- Click the "Paste area" to focus it, then press Ctrl+V (⌘+V).
- Each MIME type is listed with its contents, size and an image preview.
- Use "Copy this format" or "Copy everything" to take the data out.
Notes
- Only the formats exposed by the paste event are shown. Depending on the browser and OS, some formats the source holds may not be visible.
- HTML is always shown as text. It is never rendered, executed, or used to load external resources.
- Pasted images are previewed only inside this page. Nothing is uploaded.
- Very large text or images can be slow to display and copy.
- The clipboard may contain secrets such as passwords, so be careful when pasting during a screen share.

FAQ
Why do I see both text/plain and text/html after copying from a web page?
The source app offers the same content in several formats and the destination picks the best one it understands. A plain-text editor typically takes text/plain, a rich editor takes text/html. This tool lists every format that arrives.
Is it safe to paste HTML that contains scripts?
Yes. This tool never renders HTML; it only shows the source as text, so scripts do not run. If a script tag is present, a warning is shown.
I copied an image but only text/html shows up. Why?
Copying an image from a web page often puts only an <img> tag in the HTML format, not the image bytes. Screenshots and copies from image editors arrive as image/png or similar.
Can I see the contents of files I pasted?
You see each file name, type and size, plus a preview for image files. The contents of other file types are not read by this tool.
