Stop wasting time on repetitive tasks. Here are the essential free online tools that every developer and designer must bookmark in 2025.

Hello! This is Cheetset.

As developers, we face numerous challenges every day. Whether it's parsing complex JSON data, converting images on the fly, or calculating net salary. Searching for a tool every time and navigating ad-cluttered sites is a huge waste of time.

That's why we created this guide. Here is the Essential Online Tools Guide to drastically shorten your workflow.

1. Data Handling & Debugging

API integration and data processing are a developer's destiny. These tools ease the pain.

JSON Diff

Is the API response different from yesterday? Don't squint to find it. Use JSON Diff to instantly see additions (green) and deletions (red) side-by-side. It supports JSON5, so unquoted keys are fine.

JSON Formatter

Paste that messy JSON from your logs into JSON Formatter. It perfectly indents and organizes the data for readability.

SQL Formatter

Even complex SQL queries become readable with SQL Formatter. Write maintainable code.

2. Design & Media

Frontend developers and designers need to be precise with images and colors.

Color Palette Generator

Want to apply the mood of an image to your site? Upload it to Color Palette Generator. It extracts the 6 dominant colors and provides Hex codes.

Image Converter

Need to convert HEIC to JPG or PNG to WEBP? Image Converter performs conversions instantly in your browser without server uploads, ensuring privacy.

3. Career & Utilities

Efficiency matters outside of coding too.

Salary Calculator

Thinking of switching jobs? Check your actual monthly take-home pay after taxes with the Salary Calculator. It helps with negotiations.

PDF Merge & Split

When dealing with contracts or docs, PDF Merge and PDF Split tools are essential. No installation required.
