Clipboard Inspector

See what your clipboard really holds. One press lists every format on it, from plain text and HTML to Excel tables and images, each with its type, size and a preview. Pasting works too, and can reveal even more formats.

Everything runs locally in your browser. Your data never leaves your device.

or press Ctrl+V / Cmd+V anywhere on this page. Pasting can reveal formats the button cannot see.

Copy something in any app, then press the button above or paste right here to see every format your clipboard carries.

Next steps

Send this tool's output straight into another tool.

Convert config and data between JSON, YAML, TOML, JSON5, INI, XML, CSV and .env. Type or paste on the left, pick the output format on the right, and copy the result. Includes a format button and a minify toggle.

Shrink any image with as little quality loss as possible. Pick a WhatsApp, Instagram or Discord preset, or switch to Custom to hit a hard file size or a fixed quality, downscale with aspect-locked resolution sliders, and keep or strip EXIF metadata. Live preview, multiple images at once.

Convert images between JPEG, PNG, WebP and AVIF. Drop in as many as you like, pick a format, and dial in the quality for the lossy ones. When you convert to JPEG, choose the colour that fills any transparency. Live previews, download one or all at once.

See and edit the EXIF metadata inside a photo, then download it with your changes or save a copy with all metadata removed, GPS included. It reads JPEG, PNG, HEIC and more, and edits JPEG files.

Copy the EXIF metadata from one photo onto another without changing the destination's pixels. That covers camera model, lens, focal length, exposure, GPS and more. Choose to replace all metadata or only fill in what the source provides.

Draw arrows, boxes, text, highlights and numbered steps on a screenshot, blur or pixelate anything private, crop the result and add a watermark. Undo works as you expect, and the finished image downloads as PNG or JPG or goes straight to your clipboard.

Paste JSON to explore it as a collapsible, searchable tree, hide the fields you don't need, and see the structure it implies as a badge-annotated schema and a copyable TypeScript interface.

Convert text into every case at once: title case in the APA, AP, Chicago, MLA, Bluebook, AMA and NYT styles, sentence case, upper, lower, camelCase, snake_case, kebab-case and more, each with its own copy button.

Count words, characters, sentences, paragraphs, lines and more as you type, with estimated reading and speaking time.

Remove duplicate lines from a list or text, keeping the first occurrence. Optionally ignore case and whitespace, or drop blank lines too.

Replace text in two modes: plain find and replace all, or regular expressions with flag controls and capture group references like $1.

Paste a UUID to see what it carries: version, variant, and for time-based versions the exact timestamp, clock sequence and node. Also shows the raw bytes, the 128-bit integer and the URN form.

Decode Base64 to text or encode text to Base64. Paste into the top box, read the result below, and flip the direction with one click. Handles Unicode correctly and reads URL-safe Base64 too.

Sort the lines of a text alphabetically, naturally, by length, by numeric value or shuffled. Reverse the order with a switch, and optionally trim lines, drop blank lines and remove duplicates in the same pass.

Convert a color between HEX, RGB, HSL, HSV, HWB, CMYK, OKLCH and OKLAB. Type into any field and the others update as you go, or pick the color visually. Reads CSS color syntax and keeps alpha where the format supports it.

Check two colors against the WCAG contrast rules. Type or pick a text and a background color, read the contrast ratio, see which AA and AAA checks pass, preview real text at the sizes WCAG distinguishes, and get suggested fixes when a check fails.

Create a QR code for text, a link, an email, a phone number, an SMS, Wi-Fi access or a contact card. Set the error correction level, size, margin and colors, then download it as PNG or SVG or copy it straight to the clipboard.

Paste a cron expression and get a plain English explanation, a field by field breakdown and the next times it would run, in your local timezone or UTC. Reads five field crontab syntax, six fields with seconds, names like MON and macros like @daily.

Work out an IPv4 or IPv6 network from an address with a prefix or netmask: network and broadcast addresses, usable host range, subnet mask, wildcard mask and address type. Adjust the prefix with a slider, read the binary breakdown, and split the network into smaller subnets.

About the Clipboard Inspector

This tool shows you what your clipboard actually holds. A copy rarely puts just one thing there. Copying cells in Excel, for example, stores the selection as plain text, an HTML table and often an image at the same time, and every app you paste into picks the flavor it likes best.

Press the button to read the clipboard through the browser's clipboard API, or paste with Ctrl+V or Cmd+V. For every format found you get the exact MIME type, the size and a closer look at the content, like table dimensions for HTML, pixel dimensions for images and word counts for text.

What you can do

  • See every format your clipboard carries at once, with the exact MIME types.
  • Check what Excel, Google Sheets or Word really put on the clipboard when you copy cells.
  • View the hidden HTML behind a rich copy, including the app that produced it.
  • Inspect a copied image's format, pixel dimensions and file size, and download it.
  • Recognize what a copied text is, like a URL, JSON, a UUID, a color or Base64.
  • See name, type and size of files copied from your file manager.
  • Download any clipboard format as a file for a closer look.

How to use the Clipboard Inspector

  1. 1Copy something in any app, like spreadsheet cells, a screenshot, some text or a file.
  2. 2Press Inspect clipboard, and allow clipboard access if the browser asks.
  3. 3Or paste right onto the page, which can reveal formats the clipboard API holds back.
  4. 4Read through the formats, check the previews, and download or copy what you need.

Why the button and pasting can show different things

Browsers expose the clipboard in two ways, and they are not equal. The clipboard API behind the button is limited to a few well known formats, usually plain text, HTML and PNG images, and some browsers clean the HTML before handing it over. A real paste carries the full list of formats an app wrote, which can include RTF, custom app formats and copied files. If the button shows less than you expect, paste instead.

If the browser will not share the clipboard

Reading the clipboard needs your permission. Chrome and Edge show a permission prompt on the first read and store your choice per site. Firefox and Safari decide per read instead, usually with a small paste confirmation. If reading stays blocked, look for the clipboard entry in the site settings behind the icon next to the address bar. Pasting with Ctrl+V or Cmd+V always works, because pressing the shortcut is the consent.
