About HEEDHIPPO

HEEDHIPPO is a collection of free online tools for everyday jobs: converting and compressing images, working with PDFs, formatting text and code, calculating, and converting units. Every tool runs inside your browser, so the files you work on are never uploaded to a server.

We built it because many online converters require you to send private files to a stranger's server. Here, the processing happens on your own device. That also makes the tools fast, because there is no upload or download queue.

The tools are available in 12 languages. Many of the translations were produced with machine assistance and are being reviewed; if you spot a mistake, please tell us.
