ICNS – Apple Icon Image
ICNS is the macOS application icon format. One file holds several sizes of the same icon.
More ICNS conversionsICNS to AVIF is coming soon
We list every conversion we plan to support so you can find it later, but we only switch one on once it really works. Layered files (PSD, XCF) are flattened. EPS/PS/XPS are rendered with Ghostscript.
AVIF – AV1 Image File Format
AVIF is a modern image format built on the AV1 video codec. It supports transparency and high dynamic range, and it often produces the smallest files of any web image format at a given quality. Encoding is slower than for JPG or WebP, and older browsers and some apps cannot open it.
More AVIF conversionsHow this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
