What MigaBuilder is
MigaBuilder is a collection of free tools that work right in your browser: edit and sign PDFs, make a CV or an invoice, fix photos, convert files, build a website, make games, cartoons, music and videos, and learn with interactive maps, quizzes and tests. There are no accounts, no watermarks and no surprise paywall.
Private by design
Most tools do their work on your own device, so your files are never uploaded. Tools that need an online service, such as an AI step or a video room, say so with a label on the homepage and on the tool page. Read exactly what is sent in the privacy policy.
Who makes it
MigaBuilder is an independent project run by one owner, built together with AI assistants (Claude, ChatGPT and Gemini) and checked automatically: every change is tested in a real browser before it goes live, and every tool has a short narrated video guide. You can read how that works on How MigaBuilder is built, and see all of the code on GitHub.
How it stays free
The tools are free. The site is supported by optional templates in the shop and by donations.
