About ConverterTools
ConverterTools is a free collection of online file conversion tools that run entirely in your browser. Convert images, documents, spreadsheets, and data formats — instantly and privately.
Our Mission
We believe file conversion should be simple, fast, and private. Too many conversion websites require you to upload your files to unknown servers, wait in queues, or pay for basic functionality. We built ConverterTools to be different.
How It Works
Every conversion on ConverterTools happens directly on your device using modern browser technologies. When you select a file, it is processed by JavaScript running in your browser tab — nothing is uploaded anywhere. The converted file is generated locally and downloaded straight to your device.
What Makes Us Different
100% Private
Your files never leave your device. We cannot see, access, or store anything you convert.
Completely Free
No sign-ups, no limits, no premium tiers. Every tool is free to use as many times as you want.
Instant Results
No waiting for server processing or sitting in queues. Conversions happen instantly on your machine.
No Installation
Works in any modern browser — Chrome, Firefox, Safari, or Edge. Nothing to download or install.
Our Tools
We offer a growing collection of conversion tools across multiple categories — including image converters, file converters, data format tools, and developer utilities. Whether you need to turn a HEIC photo into a JPG, convert a spreadsheet to CSV, or transform JSON into YAML, we have a tool for that.
Open & Transparent
We have nothing to hide. Our conversion logic runs as client-side JavaScript that you can inspect in your browser's developer tools at any time. We use minimal analytics to understand which tools are most useful so we can keep improving.
