Credits and Licenses

This page lists the open-source software that reaches your browser when you use Byterama. For each component you will find its license, its copyright notice and its version, where it states one.

On every page

Next.js, the framework the site is built with, ships its own copy of React. Your browser downloads these packages on every page:

Older browsers without JavaScript module support also download these polyfills, which come with Next.js:

On the published site, every page also loads Vercel's visit and speed statistics:

In the image tools

The image tools use this compression library to create ZIP and PNG files:

In the HEIC to JPG tool

The HEIC to JPG tool loads a WebAssembly module built with libheif. It downloads only on that page, as separate files.

The Emscripten compiler puts its own code and parts of these libraries into that module:

libheif's license lets you modify it and use your version with the site's code that calls it. The build notes explain how, and our Terms of Use allow it.

In the JPG to WebP tool

In Safari and in the browsers on iPhone and iPad, which can't create WebP images, the JPG to WebP tool loads a WebAssembly module built with libwebp. It downloads only on that page and only in those browsers, as separate files.

The Emscripten compiler puts its own code and parts of these libraries into that module:

Typeface

The text is set in Bricolage Grotesque, which we serve from our own domain:

In the printable calendar

The calendar's PDF carries the Bricolage Grotesque letters it uses. They come from its static 12pt and 12pt Condensed fonts, with their license and copyright notice:

In the QR code generator tool

The QR code generator tool makes QR codes in your browser with this library, which downloads only on that page. It is dual-licensed, MIT or Apache 2.0, and we use it under the MIT license:

QR Code is a registered trademark of DENSO WAVE INCORPORATED in Japan and other countries.
