Bienvenue sur PracticalKit

Boîte à outils web orientée navigateur pour PDF, images, données et conversions du quotidien.

Designed for Pages/CDN hosting. Prefer client-side processing to keep your files off servers.

Who runs this site

PracticalKit is maintained by a solo publisher who builds small, focused browser utilities for everyday work — PDFs, images, data formats, developer helpers, and light media tasks. The goal is simple: fast pages, clear UX, and privacy-friendly defaults (client-side processing whenever the tool allows it). The site is updated as new utilities ship or existing ones improve; see the Blog for a short changelog and practical notes.

Mise à jour de mai : texte d'accueil et style UI rafraîchis, nouvelle animation de chargement, et 2 nouveaux outils.
