The following pixel-based image formats are supported:
- JPEG* – the image format par excellence: saves storage space thanks to an intelligent combination of lossless and lossy compression. Supports 16.78 million colors (24 bit). Particularly suitable for storing photos (less suitable for flat graphics). Supports ICC color profiles and metadata standards Exif, IPTC and XMP.
- TIFF – is used when no bit may be missing. Raw data formats can be converted to TIFF without loss. Therefore larger file size than JPEG. Supports 48-bit color depth as well as the above-mentioned color profile and metadata formats. Interesting for scientific documentation or photography enthusiasts.
- PNG – compresses raster graphics without loss, supports transparency. Perfect for low-detail graphics, less suitable for photos (large file size). Does not fully support common metadata standards.
- WebP – open source and low memory requirements, supports transparency, color profiles, EXIF and XMP. Combines the advantages of PNG and JPEG. The web format of the future.
- HEIF / HEIC – modern container format, which is mainly used on Apple devices; offers several advantages over JPEG, whereby the higher image quality (at the same or smaller size) is the most important plus point.
- GIF – a format that has actually had its day, as only 256 colors are supported (8 bit). However, many individual images can be saved in one file, thus enabling animations – and so moving image memes are often seen as animated GIFs.
- BMP – The bitmap format was released with Windows 3.0 (1990). It is known from Microsoft Paint. BMP files are uncompressed, so they were unsuitable for Internet applications due to their size. The format is hardly used today.
- PSD – proprietary format from the image editing programme Adobe Photoshop.
* .jpeg and .tiff are unabridged file extensions. As DOS and older Windows versions only allowed three characters as an extension, they are still often shortened to .jpg or .tif.
