Krita is specialized in. Lossy file formats, like JPG or webP are an example of small on disk, but lowering the quality, and are best used for very particular types of images. Lossy thus means that the file file format plays fast and loose with describing your image to reduce filesize. Non-lossy or lossless formats, like PNG, GIF or BMP are in contrast, much heavier on disk, but much more likely to retain jxl *.kpl *.kra *.ora *.pbm, *.pgm and *.ppm *.pdf *.png *.psd *.svg *.tiff • *.webp • Lossy and Lossless Image Compression ### *.bmp .bmp, orBitmap, is the simplest raster file format out there
