About ToolSuite

738 tools that convert, clean, measure and inspect the files and text people deal with every day. No account, no upload quota, no watermark on the result, and no “upgrade to remove the limit” on the second use.

641 of the tools never send anything to a server. That is partly a privacy decision - a file that is never uploaded cannot leak - and partly an engineering one. Browsers already contain image codecs, compression, cryptographic hashing and a full text engine. Using them means the result appears instantly, the site costs almost nothing to run at scale, and a traffic spike cannot take it down.

The remaining tools need software a browser does not have: FFmpeg for video and audio, LibreOffice for Office formats, Ghostscript and Poppler for certain PDF work. Those run on isolated workers with no network access, strict time and memory limits, and automatic deletion of both the input and the result.

A tool appears on the site only when it genuinely processes its inputs, handles bad input with a readable message, works on a phone, and has its own tests. Anything that does not meet all four stays out of the navigation and out of the sitemap. There are no cards that lead to empty pages and no buttons that do nothing - the implementation matrix in the repository lists the status of every planned tool, including the reasons some are not shipped.

Next.js and TypeScript on the front, Node.js workers behind a job queue for the heavy formats, MySQL for the small amount of state that genuinely changes at runtime. Tool behaviour comes from shared engines rather than a thousand separate implementations: a converter configures an engine, it does not reimplement one. Every dependency is permissively licensed and listed on the licences page.

There is no advertising and nothing is sold. Running costs are covered by optional donations - if a tool saved you a job, you can support the project, and if it did not, it is still free.
