Tools should solve problems, not add steps
SodaTool focuses on small, well-defined tasks: open, process, done. No bulky software to install for a one-off conversion, and no complex workflow to learn first.
For tasks suited to local computing, files are processed in your browser first.
Frequently Asked Questions
Quick notes on free usage, file handling and browser compatibility.
Does SodaTool require download or installation?
No. Most tools run directly in your browser, on both desktop and mobile. Frequently used tools can also be added to your desktop as a PWA.
Is it safe to process files online?
Tools that can run entirely in the browser process files locally first. Before using a specific tool, you can check its data handling and privacy notes on the tool page.
Are these online tools free to use?
SodaTool's everyday online tools are free to use — no software installation needed for the basic features. A few features that rely on third-party services may have reasonable usage limits.
Can I use it on my phone?
Yes. The homepage and tool pages are fully responsive; for complex file editing, a desktop screen gives you more room to work.
