Licences and credits
This site serves open-source code and fonts to your browser. That carries obligations, and this page is how they are met.
Why this page exists
When you load a page here, your browser receives typefaces and, when you convert a file, JavaScript and WebAssembly compiled from open-source projects. That counts as distribution, and the licences involved require the notices below. Full licence texts are linked next to each entry.

LGPL notice. This site distributes libheif and libde265 in compiled form as part of the conversion bundle. Both are licensed under the GNU Lesser General Public License, version 3. You may obtain the complete corresponding source from the project repositories linked above, and you are free to modify the library and relink it: the bundle is served as a separate, unbundled file at /lib/heic2any.min.js, so a modified build can be substituted for it. Neither library is modified for use here.

The font files served here are subsets, reduced to the Latin character set and converted to WOFF2 for size. Subsetting is permitted by the Open Font License. The files retain their original names and are not sold, and the licence text accompanies them as the OFL requires.

A note on HEVC patents
HEVC, the codec inside a HEIC file, is covered by patents administered by several licensing pools. That is the whole reason browsers ship no HEVC encoder and Windows charges for its codec. Decoding here is performed by open-source software running on your own device. Nothing on this page is legal advice, and anyone building a commercial product around HEVC should take their own.
Common questions
- What open-source software does this site use?
- heic2any for decoding, which bundles libheif and libde265 compiled to WebAssembly, plus JSZip for archives and jsPDF for PDF output. Typefaces are Archivo and IBM Plex under the Open Font License.
- Why does the LGPL matter for a website?
- Serving compiled LGPL code to a browser is distribution, which requires the licence text, attribution, access to the corresponding source, and the ability to substitute a modified build of the library.
- Are the product names on this site used with permission?
- They are used descriptively to identify the products the guides explain, which does not require permission. The site is independent and claims no affiliation or endorsement.
