SOFTWARE NOTICES
Software licenses.
PicPropper application
The original application code, design, and branding are reserved under the PicPropper application license. Third-party components retain their own licenses. The application license permits replacing the LGPL libraries and reverse engineering to debug those modifications.
HEIC decoding
This site includes libheif 1.23.4 and libde265 1.1.3 under LGPL-3.0-or-later. The decoder is a separate replaceable module. Its source bundle contains exact upstream sources, our browser-limit adapter, build scripts, and tests. Compiled application files and instructions are provided for recombining the application with a modified decoder.
- Decoder source and build materials
- Compiled application replacement kit
- Application and decoder replacement instructions
- libheif license (including LGPL and GPL texts)
- libde265 license
- Decoder build instructions
WebP export
Browsers without native WebP export use libwebp 1.6.0 locally. Its BSD-style license, WebM patent grant, authors, build instructions, and source bundle are available here.
PDF processing
PDF merging uses pdf-lib (MIT), including standard fonts, UPNG, and pako. Previews use PDF.js (Apache-2.0); bundled fonts and decoders retain the notices in their distribution.
Runtime components
Emscripten and its runtime components have their own notices: Emscripten, musl, libc++, libc++abi, compiler-rt, and libunwind.
Astro and fflate use the MIT license. These third-party licenses do not apply to the entire original PicPropper application. Software licenses do not constitute a grant of every potential codec patent right.
