Similarly, most other image file formats, such as JPEG, TIFF, PNG, and GIF, also store

bitmap

images (as opposed to vector graphics), but they are not usually referred to as bitmaps, since they use compressed formats internally.

What is difference between vector and bitmap image?

The difference between bitmap and vector is that

the bitmap graphics use pixels to represent images while the vector graphics use basic geometric shapes to represent images

. In brief, in vector format, the picture quality remains as it is, regardless of the size.

Is PNG a bitmap file?

(PNG) are different from JPEGs because they use “lossless compression”. This means a PNG can be compressed to a smaller file size without losing any of the detail in the image.

Is bitmap lossy or lossless?

Bitmap formats such as BMP generally are

uncompressed

, although there also are compressed BMP files as well. Lossy compression formats are generally suited for photographs. It is not suited for illustrations, drawings and text, as compression artifacts from compressing the image will standout.
