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.

JPG Image Compressor

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.

Image Converter

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.

EXIF Editor

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.

EXIF Transfer

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.

Image Annotator

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

JSON Inspector

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.

JSON Diff

Compare two JSON documents by structure and see every added, removed and changed key and value with its exact path. Browse the result as a tree, a filterable change list or a line diff, ignore array order, catch type changes and export the changes as a JSON report.

Text Case Converter

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.

About the Clipboard Inspector Tool

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

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

Aspect Ratio Calculator

Enter a resolution to get its simplified aspect ratio, or start from a ratio and one side to get the missing dimension. Knows the common ratios like 16:9, 4:3 and 21:9 and shows how close your size is to each.

Checksum Validator

Verify a checksum online: drop a file, paste the expected checksum and see instantly whether they match. The hash type is detected from the checksum itself, covering MD5, SHA-1, SHA-256, SHA-512, BLAKE3, CRC-32 and more, and sha256sum lines or whole checksum files can be pasted as-is.
