# Avalon > Avalon makes free online tools for PDF files, images, video, audio and everyday calculations, plus small digital products. Most tools run in the visitor's browser with no sign-up and no watermark; AI PDF needs an account and Pro+ credits. The site also publishes write-ups of its own projects and APIs for developers and AI agents. Pages are in English; the home page and the tool pages are also published in Spanish (/es/tools/), Brazilian Portuguese (/pt-br/tools/), French (/fr/tools/), German (/de/tools/), Japanese (/ja/tools/), Indonesian (/id/tools/), Hindi (/hi/tools/), Korean (/ko/tools/).
