184 free tools across 17 categories — images, PDFs, colours, text, calculators and converters
CodBolt started as a handful of data conversion tools and grew into something wider: 184 free tools across 17 categories. Alongside the JSON, CSV and XML converters it began with, there are now image tools, PDF tools, colour tools, text tools and calculators. The idea has not changed — the small jobs that usually cost you a download, a sign-up or a watermark should just be a tab you open.
Our platform is built on the principles of privacy, performance, and simplicity. Every tool is designed to work seamlessly in your browser, ensuring your data never leaves your device unless you explicitly use our API services.
JSON, CSV, XML and YAML — convert, format, validate and compare, with encoding and number-base tools alongside.
Compress, resize, crop, upscale and merge images, and split, rotate or watermark PDFs.
An interactive colour wheel, palette generators, HEX and RGB conversion, and WCAG contrast checking.
GPA and CGPA, EMI, GST, BMI, pregnancy and due dates, percentages and everyday date maths.
All processing happens in your browser. Your data never leaves your device unless you use our API.
Optimized algorithms and client-side processing ensure instant results.
No registration, no credit card, no hidden fees. All tools are free forever.
Fully responsive design works seamlessly on desktop, tablet, and mobile devices.
CodBolt is built using cutting-edge web technologies to ensure reliability, performance, and security:
Hi, I'm Bhavesh Sorathiya — an independent developer with a passion for building tools that make everyday tasks faster and simpler. CodBolt is my vision of what online tools should be — fast, free, and hassle-free.
With 12+ years of experience in .NET, C#, .NET Core, Web, WinForms, Amazon Bedrock, and AI/ML — including building AI-powered voice cloning applications — I bring that same engineering depth to every tool on CodBolt.
CodBolt is just getting started — AI-powered tools, bulk processing, and much more coming soon.
"Every tool I build has one rule: it must just work."
