Three New Browser Tools for JSON, Images, and Markdown

Small checks often happen between larger tasks: comparing a configuration change, choosing colors from a reference image, or finding every link in a document before publishing. Three new OnlineTools360 tools keep those checks in one browser tab and process the input locally.

Compare JSON without reading every line

The JSON Diff Checker parses two JSON documents and reports the paths that were added, removed, or changed. This is useful for API responses, configuration files, fixture updates, and release reviews where ordinary text diff can hide structural changes behind formatting differences.

• Use the path shown in each result to jump directly to the changed property.
• Arrays are compared as values, so reordering or replacing an array is visible as one focused change.
• Invalid JSON is reported before a comparison is attempted.

Build a palette from an image

The Image Color Palette Extractor samples an uploaded image in a temporary browser canvas and returns its five most common color buckets. It is useful when starting a landing page, matching an illustration, or turning a product photo into a quick color reference.

The extracted hex values can be copied individually or as a complete palette. Because the image is processed locally, the source file is not sent to a server by the tool.

Audit Markdown links before publishing

The Markdown Link Extractor lists normal Markdown links, image references, and angle-bracket autolinks. It helps with documentation updates, README reviews, migration work, and editorial checks where a missing or incorrectly formatted destination can be easy to overlook.

The tool does not request the URLs or claim that they are reachable. It extracts what is written in the Markdown so you can review the destinations and copy the URL list for a separate check.

Keep the workflow local and focused

These tools are designed for short, repeatable checks. Paste the data or select the file, review the result, and copy only what you need for the next step. No account or upload queue is required.
